I think the best examples of what I would like to do can be found at the KIDS website. http://kids.fao.org and then under "Application Examples". Another good example is at http://www.fao.org/landandwater/agll/agromaps/interactive/index.jsp I am not starting with individual points (well, maybe but the data has already been aggregated). The question for me is whether it would be easier to modify KIDS (also open source) or Mapserver to accomplish what I would like to be done. I agree, that it seems that it in principle should be able to be accomplished with Mapscript. It seems less obvious to me how to implement this functionality in KIDS, as it doesn't have the same sort of scripting support as Mapserver. I agree that there may be a way to do it, but I thought if someone has proven that it can be done, it would be good to start there instead of coding from scratch. I will checkout the developers mailing list as well to see what is there. Thanks for the tips.

So you have shapefiles or tables in PostGIS that have polygons with your data in them? I'll assume that for this discussion we're talking about a table with polygons with an attribute called "IndicatorValue" that holds your data value. To draw the maps you're looking for, you'll need to have a layer in your mapfile that looks something like this: LAYER ... CLASS EXPRESSION 'IndicatorValue < 10' COLOR 255 0 0 #whatever END CLASS EXPRESSION 'IndicatorValue < 20 AND IndicatorValue >= 10' COLOR 255 0 0 #whatever END ... END The EXPRESSIONs will vary depending on your source (PostGIS or Shapefiles, etc). Your issue is that you want the user to be able to set the number of classes, and the boundary values (10, 20, etc.). This is entirely doable right now in Mapserver using Mapscript. There is no need to wait for the COLORRANGE support that's being discussed on -devel. That is really being designed for people who want continuous color changes based on attributes, not just ranges. It's true that some of the possible approaches there might make this easier, so you might want to keep an eye on that, but I would not really recommend that you rely on it. At its most basic, Mapscript lets you edit a .map file at runtime programatically before it renders the image. It loads up the .map file into an object, lets you do stuff like change parameters, add classes, etc., and then lets you generate the map. That means that you could have a HTML form that asks them for the # of groups, and the high/low values and then your script (Python, PHP, Perl, etc.) could use those to modify your map. I'm not the Mapscript guru here (there are many), but it doesn't seem that your request would be much of a challenge. Now, if you were trying to aggregate points into areas, there would be other issues. However, it's still doable. So, choose your poison (PHP, Python, Java, Perl, Ruby, TCL, C#, C++, C) and ask the list for an example in that language. Someone will respond, and in a week or so (after you have Mapserver itself running), this should work.

I've done it without mapscript http://imaptools.com/~woodbri/thematic/thematic.cgi?name=ThemeMap&cmd=Map&debug=&location=MA&method=kmeans&numclasses=10&demographic=DP40063 It would be better with the COLORRAMP support or if I played a little more with mapscript or the mapfile.

Tom, My understanding is that now (as of 4.4 or 4.6?) tileindexes can be any feature data source that works as a layer. So PostGIS should be fine. However you would need to declare the tileindex as a distinct layer and then reference it from the target raster layer. However, I am less clear on how the WMS interaction would work.

Chip, This can be accomplished with OGR using the .csv (or ODBC) reader along with the VRT driver and the shapefile writer. The idea being that the.csv or ODBC reader can access non-spatial input tables, the VRT driver (along with an XML description file) indicates which columns to use for X and Y, and then the result is written with the shapefile writer. http://www.gdal.org/ogr/drv_csv.html http://www.gdal.org/ogr/drv_odbc.html http://www.gdal.org/ogr/drv_vrt.html http://www.gdal.org/ogr/drv_shapefile.html The only tricky part of this process is preparing the VRT file.

I would suggest you read the section of the Raster HOWTO on scaling non-8bit data, but the quick thing to test is to add: PROCESSING "SCALE=AUTO" in your layer definition. > Second thing, it is possible to import a coloro schema > (.lyr) file? No, there is no support for .lyr files. Generally speaking you will need to define a bunch of CLASSes with colors for different ranges of your field. This is also covered (briefly?) in the raster howto.

I believe Apache can be configured to take the output from mapserver and send it through PHP. This kind of chaining is tricky, but it does work. I believe the trick is having the CGI (mapserv or a wrapper) return an appropriate MIME type althought I'm not sure how at the moment. Another alternative (that I've actually used) is to have the template go to a simple HTML pages that does a META refresh a full URL that includes the needed parameters for the PHP to work. That is, you make a template that just does a 302 forward. The client double-pumps and fetches your PHP file which Apache handles normally. This requires no reconfiguraiton of Apache and works without having to use Mapscript.

I think you need to use layer->getItem(int i) E.g. in a query context: $qshape = $layer->getFeature($qid, $tid); for($i = 0; $i < $qshape->{numvalues}; $i++) { $val = $qshape->getValue($i); $name = $layer->getItem($i); } See also: http://zcologia.com/mapserver/querying-howto#resulting-features From warmerdam at POBOX.COM Tue Oct 4 06:23:18 2005 From: warmerdam at POBOX.COM (Frank Warmerdam) Date: Tue, 4 Oct 2005 09:23:18 -0400 Subject: Can Mapserver 4..6.1 read GML3??

So the answer is basically no, though it might work in some simple GML2-like cases.

So, it isn't really GML3 ready though as I mentioned some simple GML3 products might work. I would suggest you try out the files in question with the GDAL 1.3.1 ogrinfo and see if they work ok.

Also, I get: locate gd.h /usr/include/gd.h /usr/include/php/ext/gd/php_gd.h /usr/include/php/ext/gd/libgd/gd.h On a FC2 box and on a FC box: whereis gd.h gd: /usr/include/gd.h (locate is turned off by default on FC4 and I've not needed to re- enable). Did you install/compile these by hand? It would have been easier to grab as much as possible from from the YUM repositories. Also, you'll need the php-gd if you want to use php with mapserver (from you configure line).

When I use a map that has eg. a projection like Lambert Equal Area Azimuthal and I load a context file where the specified is and the SRS for the layers is EPSG:4326 then the map will automatically be reprojected to the SRS set in the of the loaded Map Context file. Also the map size changes from the original settings to the ones specified in the context file under and the map extent is set to the values of . Why is this behaviour intended to be like that? If one omits the then the WMS layers are loaded to the map but the original projection is kept. But a context file without it is not correct according to the context schema. Ok, I can reset the map parameters after loading the context file to the original settings.

This is mostly a bug fix release, though there are a few new and improved drivers. Source: http://www.gdal.org/dl/gdal-1.3.1.tar.gz http://www.gdal.org/dl/gdal131.zip Docs / Web site: http://www.gdal.org/dl/gdal131doc.zip Test Suite: http://www.gdal.org/dl/gdalautotest-1.3.1.tar.gz The major news with this release is that the "Next Generation" Perl, Python and Ruby bindings are now considered ready to use, though I'm sure there will be some additional improvements to them in the coming months. I would like to give out a special thank you to Ari Jolma (perl), Charlie Savage (Ruby), Kevin Ruland (Python + overall NG work) and Howard Butler who have put in a huge amount of effort on these bindings. If we can get champions for Java, C# and PHP that are willing to brave the dark depths of SWIG, I'm sure we can make good progress on them too.

PCRaster Driver: - libcsf is now included as part of GDAL. - PCRaster enabled by default on win32. - --with-pcraster=internal option now supported on unix (but not yet default) VSI Virtualization: - The "large file API" (VSI*L) has been re-engineered to allow installing additional file handlers at runtime. - Added "in memory" VSI handler so that now any driver using VSI*L functions for data access can operate on in-memory files. - PNG, JPEG and GeoTIFF drivers upgraded to work with in-memory support. Raster Attribute Tables: - Implemented new Raster Attribute Tables support. See the GDALRasterAttributeTable class for more information. Erdas Imagine Overviews: - Erdas Imagine driver upgraded to support building internal overviews. - Generic overview handler updated to support overviews in Erdas Imagine format for any file format. Set USE_RRD config option to YES to enable. gdalwarp: - Added proper support for "unified source nodata", so the -srcnodata switch works well. RIK Driver: - New Swedish format driver implemented by Daniel Wallner. JPEG Driver: - Substantial improvements to EXIF support. MrSID Driver: - Updated with proper JPEG2000 support as JP2MRSID driver, including encoding with ESDK. - Updated to support MrSID Version 5.x SDKs. PNG Driver: - Fixed serious bugs with 16bit file support. - Added NODATA_VALUES to identify RGB sets that indicate a nodata pixel. OGR 1.3.1 - Overview of Changes ------------------------------- Reference Counting: - OGRSpatialReference and OGRFeatureDefn now honour reference counting semantics. - Note that, especially for the OGRFeatureDefn, it is now critical that all drivers be careful with reference counting. Any OGR drivers not in the core distribution will likely crash if not updated. ESRI Personal Geodatabase Driver: - New driver implemented for ESRI Personal Geodatabase (.mdb) files. - Uses ODBC, enabled by default on win32. ODBC Driver: - Updated to support binary fields. - Updated to support WKB geometry fields. - Updated to support DSN-less connections. S57 Driver: - Added support for Inland Waterways, and Additional Military Layers profiles From dianajimena at GMAIL.COM Tue Oct 4 14:09:11 2005 From: dianajimena at GMAIL.COM (Diana Jimena Pacheco Solano) Date: Tue, 4 Oct 2005 16:09:11 -0500 Subject: qstring Message-ID: Hi!!

PostGIS has a function called Simplify which could simplify geometries, use that function to create a new simplified table. Simplify(geometry, tolerance) Returns a "simplified" version of the given geometry using the Douglas-Peuker algorithm. Will actually do something only with (multi)lines and (multi)polygons but you can safely call it with any kind of geometry. Since simplification occurs on a object-by-object basis you can also feed a GeometryCollection to this function. Note that returned geometry might loose its simplicity (see IsSimple) Best regards, Bart Bart van den Eijnden Syncera IT Solutions Postbus 270 2600 AG DELFT tel.nr.: 015-7512436 email: BEN at Syncera-ITSolutions.nl >>> Jos?

You can check quickly whether the colortable is found by using gdalinfo on the binary grid.

However, when we request a portion of the data that crosses the date line, there is a large gap created in the output image. We've tried using different projections, but the gap appears regardless (in native projection -- mercator, and in geographic). A sample GetMap is below, but I've deleted the server name as it's not public yet. The data are properly georeferenced, they line up fine with other layers in commercial and open source GIS packages.

In theory though, you could probably take the installation from the installer, zip it back up, and do an unzip'n'run with it. There might be a few changes you need to make, but not many.

One on Mapserver 3.6.1 and the other on 4.6.0 The 3.6 site is on a Duron 750 with 256Mb RAM and an IDE drive. Webserver is Apache 1.3x The 4.6 site is on a Celeron 1.7GHz with 256Mb RAM and a similar IDE drive. Webserver is Apache 2 Both sites use an identical interface and have the same datasets. The 4.6 has a few extra raster tiles in full colour. My issue is the 3.6 site is at least twice as fast at creating a map image as the 4.6 site. This is when they both have the same datasets and extents selected and the same (gif) output format. Speed difference appears to be the same for either raster or vector. I've used tileindexes, shptrees and sortshp to optimize speed on both sites so I'm starting to look beyond data any differences in how the data is presented to the the sites. Has anyone else had a similar experience or has any ideas? Currently I suspect it might be down to build differences. Is that feasible? Thanks for any help.

With annotation layers the symbol is tied to the text and both are used in computing label collisions. Now, if you don't have text you want to display you can just draw a whitespace (" ") using the class text parameter and this will still work. You may want to sort your datasource so that restraunts or hotels get precedence. Problem is though that you have to give up one or the other. One other idea might be to offset hotels and restraunt symbols in opposite directions just a bit so the can apprear side-by-side. Styles support an OFFSET parameter. You still might consider processing the data though. For example, if you could use TrueType markers then you could create an "ammenties" string for each address that could reference multiple business types. The string would be output as a series of symbols centered on a point.

Jeroen, I had been treating the native format as free text but I am not sure that is proper. I suspect the intent was that it match one of the available formats, and allows clients to request things in the native format so as to preserve the truest form of the original data.

That is why things are crashing. I don't know why it is NULL though. I really think you may need to submit a bug report with all the information (map file, data, invocation, full traceback etc) to reproduce the problem so the developers can track it down and fix it properly.

I would strongly encourage you to execute the gdal_merge.py script from the "FWTools Shell", or to call the same environment initialization bat file it uses (the setfw.bat file). Also, in the BIN directory of FWTools there is a gdal_merge.bat. If you use that, it will take care of calling the right python executable.

Jerl, There is no such thing as an RGBA (or RGB) GIF file. Ideally MapServer would realize this (sooner) and blow a gasket when it encounters your OUTPUTFORMAT declaration. If you submit a bug report and see that it is assigned to me I'll try and fix that. If you want RGB or RGBA output format use a format that supports it like PNG.

I have moved on a bit http://home.lsces.co.uk/bitweaver/mapper/display_map.php has it integrated with the bitweaver framework ready for adding additional facilities. The refresh problem relates to the way the browser loads the last file accessed.

It makes sense that native format *should* be one of the supported formats (the annotation in the schema says as much). That does cause a problem because it would mean any format the GDAL could not write could not be referenced as a native format- that's not good. I suppose you'd just ommit it in that case. The formats code list itself is created from the wcs_formats metadata which needsto match the names of the various output formats you define in the metadata. So, in short, wcs_nativeformat should match one of the formats listed in wcs_formats. It will not break anything if that is not true. Perhaps we should enforce this. The WCS how-to is not intended to exist apart from the implementation specifications, so you may at times need to refer to that document. Should you find errors or need more information then please contact me. Help enhancing documentation would be most welcome. Steve >>> Jeroen Ticheler 10/06/05 9:41 AM >>> Hi! I would like to have some more background on some items of the map file used for a time series WCS. I ran into the element "wcs_nativeformat" that has the value "raw binary" in the WCS samples. Are the values for this item free text, or should they be a value from a restricted list. (Or should I dive straight into the OGC-WCS specs now?) Other elements listed also lack information on their use. Can I help to improve them or is anyone planning to update the page? Thanks in advance.

It makes sense that native format *should* be one of the supported formats (the annotation in the schema says as much). That does cause a problem because it would mean any format the GDAL could not write could not be referenced as a native format- that's not good. I suppose you'd just ommit it in that case. The formats code list itself is created from the wcs_formats metadata which needsto match the names of the various output formats you define in the metadata. So, in short, wcs_nativeformat should match one of the formats listed in wcs_formats. It will not break anything if that is not true. Perhaps we should enforce this. The WCS how-to is not intended to exist apart from the implementation specifications, so you may at times need to refer to that document. Should you find errors or need more information then please contact me. Help enhancing documentation would be most welcome. Steve >>> Jeroen Ticheler 10/06/05 9:41 AM >>> Hi! I would like to have some more background on some items of the map file used for a time series WCS. I ran into the element "wcs_nativeformat" that has the value "raw binary" in the WCS samples. Are the values for this item free text, or should they be a value from a restricted list. (Or should I dive straight into the OGC-WCS specs now?) Other elements listed also lack information on their use. Can I help to improve them or is anyone planning to update the page? Thanks in advance.

I wonder if it is possible to modify the class expressions via the WMS GetMap-request ?? Or can this only be done by WFS? You can see the application here at: http://161.111.161.171/Atlas/ It contains maps of 3 thematic groups (species distribution maps, maps on biodiversity indices and environmental factors) and a query that allows to generate a list of species, biodiversity indices and environmental factors for each graticule. The species distribution maps are what I would like to make available as web map service but I can't figure out how to pass the parameter on that indicates the species code. The problem is the layer 'Dlyr', my species distribution layer. As for the application, the user selects a species name from a list and this variable is then used to render the map by modifying the predefined classes in the map file. $clObj0=$Dlyr->getClass(0); $clObj0->setExpression('(['.$sp.']=0)'); $clObj1=$Dlyr->getClass(1); $clObj1->setExpression('(['.$sp.']>0 AND ['.$sp.']<=20)'); $clObj2=$Dlyr->getClass(2); $clObj2->setExpression('(['.$sp.']>20 AND ['.$sp.']<=40)'); $clObj3=$Dlyr->getClass(3); $clObj3->setExpression('(['.$sp.']>40 AND ['.$sp.']<=60)'); $clObj4=$Dlyr->getClass(4); $clObj4->setExpression('(['.$sp.']>60 AND ['.$sp.']<=80)'); $clObj5=$Dlyr->getClass(5); $clObj5->setExpression('(['.$sp.']>80)'); The class ranges never change, no matter what species is selected. The species code $sp identifies a column in a PostgreSQL table, i.e. [DEMI]. Each species has its table column. I have already prepared a first version that you may try typing this in your browser: http://161.111.161.171/cgi-bin/AtlasAves.exe?service=WMS&request=GetCapabili ties You may retrieve a map composition, for example... http://161.111.161.171/cgi-bin/AtlasAves.exe?service=WMS&version=1.1.1&reque st=GetMap&layers=fondo,Dlyr,cuad50,cuad_anno&format=png&transparent First, the client has to have as well a species list that allows to select and pass on the species code (I will later make this list available). How is the species identifier added to the request string ? I guess, this calls for providing the layer as WFS instead (?). The client then creates his own classes and I don't have to modify my code at all? Is it possible to avoid that the whole data set is retrieved by a GetFeature-request? I tried by specifying 'wfs_maxfeatures', but it had no effect on the GetFeature response. I am using MapServer 4.4 and this layer is a PostGIS table.

See section 2.2 in http://zcologia.com/mapserver/querying-howto. This is one of mapscript's worst quirks. The second argument of queryByAttributes becomes a temporary layer filteritem, and the third argument becomes a temporary layer filter. See http://ms.gis.umn.edu/docs/howto/msexpressions/howto_view If you don't actually have a 'number' item in the layer, then the query will fail and getResults() will return NULL.

Hi David, If I understand correctly what you need, all you want is to have multiple CLASS sections, asper the p. 161 example here: http://examples.oreilly.com/webmapping/ FYI - to all others, most of the map file code examples from my book (some still remaining) are on that website.

The mapfile you pointed me to above looks like it has an Expression associated with the 'Bulgaria' class as: CLASS EXPRESSION ( ' [NAME] ' ne 'Bulgaria' ) STYLE OUTLINECOLOR 100 100 100 COLOR 200 200 200 END END Whereby I assume the [NAME] gets pulled from the URL such that 'Bulgaria' may or may not receive that color depending on what's in the URL. What I want to do is fill [NAME] from a recordset obtained from SQL Server. At the moment, I have a series of Classes associated with my State/Province layer. So, does this mean all I have to do is add expressions as you showed like [NAME1], [NAME2], ....., [NAMEx] for all the State/Province classes and somehow figure out how to fill these from a SQL Server recordset?

OK, now I see that 'ne' above means not equal...my mistake. But, I think I can phrase my question more clearly now that I see what you have here.

I would say this is more of a job for MapScript. Can you script it up in PHP instead? Doing things via a URL start to get quite limiting when trying to do dynamic stuff like this, it's not always impossible though it sometimes can be.

I have not yet decided whether I want to provide the species distribution maps as WMS or WFS. On one hand WMS would make things easier for clients, on the other hand WFS has a lot more to offer. In THIS case the data are freely available but people are usually a bit more anxious about their data - so I am interested in both ways. I have my application running as usual, but this is NOT the one that receives requests from cascaded servers. For this purpose I have a second mapfile (I guess this is what Adam calls a pseudoserver). It makes use of a mapfile which is stripped down to the essential (no titles and no embedded legend) and has all the necessary metadata to be requested by clients. Anyway, for now the problem is how to tell which species (out of almost 200) is to be shown. I was hoping that the variable that identifies the species could be send somehow with the GetMap-request, like this: ..request=GetMap&layers=Dlyr&species=meap (this is the common Bee eater) or this way: ..request=GetMap&layers=Dlyr&meap But this is probably not understood, since the variable is not an expected element in this request. If I had a SQL statement with a filter I could perhaps use the Styled Layer Descriptor, as Bart suggested. But in my case I have no WHERE clause, instead I want to SELECT a determined column out of some 200 species columns. I wish I could get the column using an alias (AS spec), then the 6 class expressions would always refer to the same alias (column) and had not to be changed at all. A sub-query like this: SELECT %variable% AS spec FROM species; I tried this for to start with: DATA "the_geom from (select species.the_geom, species.chdp as spec from species)" But I get an error message (wrong subquery). I feel there must be more in it, perhaps I am missing something? So, I still needed to provide almost 200 SLD files, one for each species. Even though the value ranges never change - the species identifier in the class expression does. Perhaps Adam's solution is a better way - use a servlet that receives the GetMap request plus the variable that indicates the selected species and then create a new instance using the CGI interface and change the mapfile parameters via a URL (see MapServer CGI Reference). $sp is the variable we would receive from the client - for example 'demi'. This is how class 3 would be changed: &map_Dlyr_class_3_expression=(['.$sp.']>40 AND ['.$sp.']<=60) We would generate a URL like this: http://161.111.161.171/cgi-bin/AtlasAves.exe?layer=Dlyr&mode=map&map_Dlyr_cl assitem=demi&map_Dlyr_class_1_expression=([demi]>0%20AND%20[demi]<=20)&map_D lyr_class_2_expression=([demi]>20%20AND%20[demi]<=40)%20&map_Dlyr_class_3_ex pression=([demi]>40%20AND%20[demi]<=60)&map_Dlyr_class_4_expression=([demi]> 60%20AND%20[demi]<=80)&map_Dlyr_class_5_expression=([demi]>80%20AND%20[demi] <=100) Now I get curious how Adam makes his pseudoserver behave like a mediator, parse the incoming request, send the URL and return the result to the client. I have not yet configured my system for servlets, but If you don't mind, Adam, yes I would like to see such an example.

Message-ID: Hi, A question that came up while discussing integration of MapServer with a catalog application (GeoNetwork opensource) was if mapserver in CGI mode could use a map file coming from another server; a URL (used for OGC-WMS services) would look like this: http://localhost/cgi-bin/mapserv?map=http://remotehost/mapfile.map or, in the way we were thinking of using it for example as: http://localhost/cgi-bin/mapserv?map=http://localhost/geonetwork/map? id=20 It would allow us to store map files in our catalog, with the metadata and run the W*S services straight out of the repository. In fact, we coud/would use the metadata information to generate a map file with all the required metadata & data elements set based on the metadata. SLD documents for different styles could also be stored with the metadata at that point. We would use XSL transformations to generate the (final) map files.

On a UNIX/Linux system you can easily do it by yourself: - Create a shell script that grabs the 'map' parameter from the paramter line. - Have wget, curl or a similar tool downloading the map file from the remote site and storing it into a local directory. - Have 'sed' or a similar tool replacing the mapfile link in the argument list - execute the real mapserver with the modified parameters Have fun, Dirk.

Message-ID: Hello, I am exploring the possibility of using MapServer to serve up MODIS satellite imagery as a WMS. I have managed to create a working mapfile containing a single raster image for a single day. I need to to serve up a 2nd image which covers the same geographic extents but is from a different date. Ultimately, I want to serve up years of daily images, hence my desire to use the time dimension. Searching the MapServer documentation - in the "WMS Time Support HOWTO", I found the statement "wms_ timeitem: (Mandatory) this is the name of the field in the DB that contains the time values". I am surmising that "DB" refers to database and that PostGIS is the open source database one would use with MapServer. From the PostGIS Manual FAQ "You can store point, line, polygon, multipoint, multiline, multipolygon, and geometrycollections." Therefore, I have come to the conclusion that it is NOT currently possible to use the WMS time dimension for raster data. 1) If I am wrong, can someone please point in the right direction to use the time dimension in a WMS for rasters? 2) If I am right, can someone please tell me if support for time dimension for WMS rasters is coming anytime soon in MapServer?

In-Reply-To: Message-ID: Jeff, Support for the time dimension in rasters exists, you just have to take a slight detour to get there. You want to use a "tile index" in your raster layer. This is a vector file that contains one record for each raster file. The shape should be the outline of the raster. It should have at least one attribute, which contains the file path to the raster file. For time based data, it will contain a second attribute, the date associated with the raster file. The vector "file" can be any of the Mapserver vector formats, so it can be shape file, or a postgis table, or an oracle table, etc. You can use the "tile4ms" (either part of mapserver or gdal, I am not sure) command to create a tile index from a directory of data, though it won't fill out a time stamp attribute for you. So, when mapserver is told to draw an image, it will (a) first look in the tile index to see what images fit the spatial and time extents being requested then (b) open up those images and draw them into the output image then (c) return the result.

Message-ID: Hi all: Just thought I'd share a simple image mapping example that I've been tinkering with. I needed a simple tool to allow users to select multiple features with for use in a non-GIS application. Here's the simple tool for selecting counties: http://noah.dnr.state.mn.us/cgi-bin/mapserv48?map=/usr/local/www/docs_maps/eco/rsg/search/search.map&qlayer=county&mode=nquery&searchmap=true It uses the [shpxy ...] tag to output coordinates (in pixels) via normal query templates. The searchmap option may be new to folks. It's been around a long time and is documented but is typically overlooked. It tells map server to basically compute a normalized extent BEFORE querying. That is, use the extent for an image (after pan or zoom) as the query rectangle. It really only makes sense with mode=nquery. This example uses the default extent and map size in the mapfile. This example also hilites the ability to set class expressions dynamically. Works nice and fast, and provides a very simple UI. There is one mapfile and 3 templates driving this: http://noah.dnr.state.mn.us/eco/rsg/search/search.map http://noah.dnr.state.mn.us/eco/rsg/search/templates/county.html http://noah.dnr.state.mn.us/eco/rsg/search/templates/imagemap_header.html http://noah.dnr.state.mn.us/eco/rsg/search/templates/imagemap_footer.html Perhaps this will give other folks ideas (or not)...

Or better yet have an option for auto conversion of units.

Currently MapServer does not automatically create classes based on color rules established in grass, so you need to manually recreate the classes in the layer definition in the mapfile. I would suggest reviewing the Raster howto. http://ms.gis.umn.edu/docs/howto/raster_data Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, warmerdam at pobox.com light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent From steve.lime at DNR.STATE.MN.US Tue Oct 11 07:13:34 2005 From: steve.lime at DNR.STATE.MN.US (Steve Lime) Date: Tue, 11 Oct 2005 09:13:34 -0500 Subject: Expression in MAP file . . .

Have 3 bands in the group with 0-255 each for RGB. Never got around to trying it. Since MapServer doesn't doesn't use the GRASS color info, I guess it would only work for image-type data directly, you would have to manually transform something like elevation data into 3 bands.

We have just discovered that things are working fine with MapServer 4.4. Furthermore, with 4.6.1 we did get a positive result with cgi mode (i.e. mode=map) still using the ovf file. Now, does MapServer need to be compiled with GDAL 1.3.0 for Windows? We have gdal12.dll (dated: 2005_07_19) in the cgi-bin directory. Will replacing this with gdal13.dll fix the issue or do we need a new compilation of MapServer for Windows and is it available?

The current implementation retrieves the geometry_columns table from the database in order to determine the geometry column of the table which causes an extra round trip to the server. For a suitable solution the geometry column name could be specified in the connection string as the table name. It would be also helpful to establish the ability to specify the list of the columns to select, what could restrict the amount of the data as the user's will. Theese features could provide similar opportunities as mapserver postgis driver has.

Message-ID: Hi, sorry for continuing this story, but I really want to solve this and hope my additional info helps to sort out the problems I face. I am using a shapefile with the imgdate column added to it. I use exactly the same index to work with a WCS on the same data, that one works perfectly fine. I have browsed through the mapServer sourcecode to see if I could discover something/ understand the problem better. I'm not familiar with C coding, so forgive my ignorance :-) What I could understand is that my request fails when the time string submitted in the request is compared to the timeextent given in the capabilities document. The exact section of the code is in between line 545 and line 569, apparently the msValidateTimeValue() procedure fails to find the requested date in the extent. I do not get an error when I change my extent to a range like "2005-09-11,2005-09-21/2005-09-21" or "2005-09-11,2005-09-11/2005-09-21", but it will only render the very last image, even when an earlier one is requested. So I guess I face a bug!?

First there's MapServer. This the engine under all those applications. MapServer is a server application that takes your data and create a map image. To be able to do this, MapServer has a configuration file called mapfile. To understand the mapfile, you can take the MapServer tutorial: http://hypnos.cbs.umn.edu/tutorial/ To build more complex applications, MapServer has interface called MapScript. MapScript is simply the MapServer functionality integrated in the programming language of your choice. See the doc for more details: http://mapserver.gis.umn.edu/doc.html After that, MapLab, Chameleon and GMap are three application using MapServer and PHP/MapScript. GMap is an example application using PHP/MapScript. To understand how it works, you will have to look in the code (gmap75.php) and in the mapfile (gmap75.map). MapLab is a software to easily build a MapFile for MapServer. Optionally you can build an application like GMap using GMapFactory, but this is limited. See the website for more details: http://www.maptools.org/maplab/index.phtml Chameleon is a software to easily build advanced applications using MapServer and PHP/MapScript. It's a templating system so the use is simple. You provide it a mapfile and a template and it will give you a fully functional application. The template is a simple HTML page with special tags in it. This not really a tool to create a mapfile, but you can play with dynamic layers, creating and manipulating them. See the website for more details: http://chameleon.maptools.org/index.phtml Thanks Julien On 10/12/2005 07:57 AM, Carlos Ruiz wrote: > Hello, I am Carlos Ruiz Luna, studying at the School > of Engineers of the Canton of Vaud (EIVD) in > Switzerland. > I would like to create a website with isochronous > charts by using the data bases of Tel?Atlas (Shape > format).

The problem is that the same data and mapfile have a different behaviour when i have to display graticule grids. More specifically i just have set the projection of the environment in the top part of the mapfile. All the datasets are already in that same reference systems so they don't need any projection session. I inserted 3 layers representing 3 different geographic systems (italian, UTM and Geographical) as graticules. Of course in the graticules i expressed the Projection clause relative to each reference system. In the linux environment everything works fine but in the windows don't. Apart that i get a double label along the graticule lines, the utm system is shown with wrong values and the graticule is not perpendicular but rotated with an agle of maybe 40 degrees. The fact that on one system everything works fine makes me think that there is something wrong in the 4.4.6 installation for windows and maybe it involves the italian gauss-boaga reference system epsg:25691 that i use as a base for my project, any help?

Message-ID: There are several possibilities, but a common problem in this situation is that someone will add their data to a demo application, but not modify the EXTENT in the map file to reflect the area in which their data is located. In other words, if the EXTENT of original application is defined as a box around the continental US and you add a valid data layer of Italian wine regions, you will not see your new layer because it falls outside of the extent. You can get the extent of your data by downloading OGR from http://ogr.maptools.org/ and running ogrinfo on the data file. A second common issue is that if you are trying to add your data to an existing map file, your data may be in another projection. MapServer can handle on-the-fly reprojection, but that requires you to add a few projection blocks to your mapfile.

Unless I'm missing something, (1) no substitution occurs in TILEINDEX entries in the mapfile. Example: the following substitution works perfectly DATA "/home/delabeau/wms/data/goes/%year%/%month%/%day%/%file%" but this one TILEINDEX "/home/delabeau/wms/data/modis/tc/%year%/%month%/%day%/%file%" complains msSHPOpenFile(): Unable to access file. (/home/delabeau/wms/data/modis/tc/%year%/%month%/%day%/%file%) I think the problem is in mapserv.c after line 281 (v4.6.1), where data, connection, filter and class are explicitly considered but tileitem is ignored. (2) It seems that the entire filename must be substituted, not just part: i.e, %file% works for me but %file%.tif does not. My GOES server has a single GeoTIFF for each full-disk image, so it uses a DATA statement and problem #1 is not an issue. http://map05.gsfc.nasa.gov/cgi-bin/goes?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities However, my MODIS Atlantic hurricane server creates a daily composite of individual granules using a TILEINDEX, so problem #1 causes me grief. I work around it by having my CGI front-end parse the TIME parameter and determine the appropriate date-specific layer name (e.g., 'layers=modis&time=2005-10-10' becomes 'layers=modis20051010' before Mapserv is called). http://map05.gsfc.nasa.gov/cgi-bin/modis?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities > Your users would then need to add the &time=YYYYMMDDTHHMM parameter > to their GetMap requests.

For example instead of "north || ' ' || east" you should use "east || ' ' || north". You can export the table as a shapefile using the pgsql2shp command ( http://postgis.refractions.net/docs/ch04.html#id2511474) then check it out in your favorite GIS viewer to make sure it's what you need. Once the data is set, you'll need to add the postgis table as a layer in your mapfile (see http://postgis.refractions.net/docs/ch04.html#id2512368) This will allow display the layer in your interface. Using mapserver CGI. In order to query the layer and link the selected feature to content, you can use mapserver's template feature ( http://mapserver.gis.umn.edu/doc46/template-reference.html). I'm not sure if this works with Chameleon so you might have to check the Chameleon docs on how to get that working. Hope this gives you enough to start with.

Doing this would require some code changes but could be done. My concern though is that I hate making the connection string handling too complicated. Is the query of the geometry_columns table really a significant performance issue? > It would be also helpful to establish the ability to specify the list of > the columns to select, what could restrict the amount of the data as the > user's will. I am contemplating at some point extending the OGR API to allow indicating what record elements are desired (geometry? which fields?) as an optimization for performance. However, it isn't too likely to happen immediately. Note that you can accomplish similar effects by using a custom SQL SELECT statement in the DATA field in MapServer instead of using a predefined table name. There are downsides to this approach if you are using the query mechanism of mapserver though.

With Mapserver on the backend and Google Maps on the front, you can put together some really sweet solutions.. all the data crunching power of mapserver with the usability of Google Maps: here's the javascript libs http://www.geoskating.com/gmap/gmap-wms.js and a decent example http://www.geoskating.com/gmap/nasa.html The source should be fairly self-explanatory.

Richard, I would be interested in seeing the LAYER definition you use, as well as the gdalinfo report on the input file and your IMAGETYPE and OUTPUTFORMAT declarations. Can you also supply a rendered result we could review to see the effect you mean? Normally the poor color quality issues only come up with converting to 8bit pseudocolored. But if you are really rendering to jpeg or png24 then that should not be an issue.

It will scale the values (or clip) them to 8bit and then apply the first 256 color table entries. I would suggest you create your own CLASSes manually in the mapfile instead of trying to use the .clr table.

I currently have a Linux FC4 box with mapserv 4.6 connecting to a Postgres(8.0.1)/PostGIS(1.0) backend. I have had no trouble implementing all the componets, and I am even having success with implementing a HTTP front end and am enjoying the experience. The only issue I have had, and have neglected up until now, is the problem of extents concerning the dataset described in the mapfile. I have checked the projection (AMG zone 56) using ArcGIS to make sure that I have the correct epsg projection (epsg=20256), and it seems right. So where can I go from here. I have attached a screen shot of a MapInfo connection to my WMS, and the corresponding mapfile. Any suggestions, websites etc will be much appreciated. I have searched the archives of this list, and have found similar issues, though no solution has been posted. So in the spirit of this online community, i will post a complete solution when one is obtained, including links to resources that helped.

Daniel, I am not aware of any reason the behavior would be different with MapServer 4.4 and 4.6.

Well, it is hard to know from this what version the GDAL is, but it is certainly recently dated. You could try upgrading to GDAL 1.3.1 but it is somewhat of a long shot for fixing the problem.

As far as I have read through the list there is nothing to do with EPP but a problem reading the file, but it is the spearfish soil map (just 8 bits color) so I think the problem is related with the way mapserver and gdal interacts in my computer but I'm not to sure.

User brings up map of US and sees outlines of states. (have that working - no problem). 2. User selects a state by clicking somewhere within the state polygon OR enters state name in text box (user choice - either is valid option) 3. MapServer redraws map with desired state as extents 4. User selects county from state by clicking somewhere within the county boundary polygon or enters county name in text box (user choice - either is valid option) 5.

Paco, You didn't show your layer definition in your mapfile, but it would appear that shp2img isn't getting the GRASS plugin or isn't even using the same version of libgdal.so as gdalinfo. I would suggest: o Use "ldd" to determine which versions of the libgdal.so are being used by shp2img and gdalinfo. o Set CPL_DEBUG=ON in your environment to see if there are messages from shp2img about loading the grass plugin. > On the other hand I can not read GRASS vector files with OGR > > # ogrinfo /var/www/grass5_mapserver/spearfish60/PERMANENT/vector/streams/head > Warning 1: GRASS warning: GISBASE enviroment variable was not set, using: > /usr/local/grass-6.0.1 > ogrinfo: relocation error: /usr/local/lib/gdalplugins/ogr_GRASS.so: undefined > symbol: Vect_set_fatal_error > > I think here the problem is that I did some mistake with the gdal-grass > package Likely reasons for this are that your GRASS is a bit old or that your GDAL is a bit old. What versions of GRASS and GDAL are you using? The vector driver is very new and may have some poorly understood dependencies.

If so, part of your problems is that you need to build the topology from a non-topological structure. As Flavio mentioned, FME would be a good choice for that. GRASS also has support for converting non-topological dataset to topological. If you are already starting with a topological Arc/Info binary vector coverage, then you will see from the ogrinfo reports that the topology information is available as attributes. OGRFeature(PAL):2 ArcIds (IntegerList) = (1:-349) AREA (Real) = 0.92814 PERIMETER (Real) = 5.35872 COUNTRYD# (Integer) = 2 COUNTRYD-ID (Integer) = 3027 POLYGON ((-153.022781372070312 57.383213043212891,... OGRFeature(ARC):1 UserId (Integer) = 1394 FNODE# (Integer) = 1 TNODE# (Integer) = 2 LPOLY# (Integer) = 24 RPOLY# (Integer) = 26 LINESTRING (56.360397338867188 25.983451843261719,... The ArcIds on the polygons and the node/poly information on the arcs is enough to establish the topological relationships. With a script or C++ program written on OGR you could get that information out into a text format of some kind. If you use GRASS to export to E00 you could use avcimport to convert to a binary coverage for use with OGR. FME can write binary coverages directly. Of course, both FME and GRASS offer other mechanisms to interact with the topology that might be more direct.

From what I can see in your examples, you are running into a limitation of mapserver and it's support for the time extent values. Currently the time extent can only be defined as a range value and only one range value is valid (so something like is the only thing valid 2005-09-11/2005-09-21) You should update your "wms_timeextent" and try it with only one range. I will enter documentation bug so that this limitation is clearly defined. Give it a try and let me know.

Place the code below into a xxx.kml file. To modify it for your own datasets: --Change the link the in the tag to a known working WMS source, such as your own MapServer setup set to output in the projection that Google Earth uses. --Make sure your .map file has useful extents set, and a good map size, this will control what part of the world is shown in Google Earth and at what resolution. --Change the so that when you load the layer in Google Earth, it will automatically pan to the right view (or dont, and just pan to the right spot manually) --Set the coordinates below to match the extents of the image used in your .map file **** Very Important --> The URL used in the tag ... all & symbols must be changed to & as they have been in my example. In my example, google earth pulls data from my mapserver WMS. My mapserver WMS is retrieving data from the Terra weather satellite WMS (updates daily) and the Modis forest fire WMS (updates twice a day), combining them into one image, then sending it back to Google Earth. I made it to watch the recent hurricanes. It is not dynamic, it loads once and doesnt refresh unless you remove the layer and add it again or restart Google Earth ... but there are ways of making that happen.

Can anyone tell me if I should expect a decrease in speed of image rendering moving from version 3.6 to 4.6? Currently when displaying tileindexed layer of approximately 200 shapefiles I get a big performance hit. With 3.6 images are drawn in 2s or less, with 4.6 its 4s or more depending on the number of arcs being displayed. Both datasets have been shptree'd and sortshp'd using their associated executables. There are hardware differences, they both have 256Mb RAM otherwise the 4.6 machine has a faster CPU and HD. 3.6 machine is running on RH Linux 7 Apache 1.3. 4.6 machine is running Suse 9.1, Apache2 Should I expect any performance differences between Apache 1.3 and 2?

Looks to be something to do with gcc and g++, but I haven't been able to find a solution. I'm not convinced I'm on the right path, so any advice the list can give is appreciated.

The layer is a dynamically loaded OGR (MapInfo) point layer in which I set the 'toleranceunits' to MS_MILES and the 'tolerance' to my specific radius. Then I simply run a $lyr_myLayer->queryByPoint($point,MS_MULTIPLE,0) and get the count of the results $lyr_myLayer->getNumResults (all in PHP MapScript). I am having trouble getting correct queryByPoint results. For some reason the radius seems to be smaller than it should. I have even drawn the query and then manually checked the query radius on a paper map (it is small). After a search through the list archives I could not find any similar problems . . . [I have also tried $lyr_myLayer->queryByPoint($point,MS_MULTIPLE,$radius) and I have also tried using meters and simply converting the miles radius to meters - all the same results] Perhaps I am not using the queryByPoint method correctly? Is there something extra I should know about the 'tolerance' parameter in the layer??? My map projection is: PROJECTION "proj=merc" # Mercator "lat_0=0" # latitude of natural origin "lon_0=0" # longitude of natural origin (central longitude) "x_0=0" # false easting in meters "y_0=0" # false northing in meters END and all the MapInfo data is stored in a Lat/Long projection - would this configuration cause an error???? Do I need to draw the layer before performing the query???? (I tried this on one layer and there was no noticable difference). One solution I have thought of is to manually create a layer with the correct circles to use for the radius queries, but this seems clumsy and hard to change in the future (for dynamic queries) - or perhaps create a circle feature with the correct radius and use queryByShape or queryByFeatures . . . any help would be greatly appreciated thanks tim tibben at ocf.berkeley.edu p.s. as an aside, I can use my radius as (with toleranceunits as meters OR miles): $int_queryRadius += $int_queryRadius/4.3 and I get approximately the correct results - but this is really odd!! I must be doing something incorrectly . . .

I had the impression from the code that it was virtually there already, just that it first checked for a range and does not proceed to check for ranges? The problem is that a range doesn't work for this series. Data comes in at three 10 daily periods a month, which is not exactly true as a month does not always have 30 days. Still the images are always dated with a 01, 11 and 21 for the day (or 1,2 or 3 for a dekad).

I don't know if the standard behaviour is intended like this or if it's a bug. I wanted to use pixel values because they make more sense to me than absolute distance values. With absolute values you will often find nothing for very small scales because you rarely come close enough to the point. After some trials I found out that the pixel tolerances applied by queryByPoint() seem to be valid only for the initial extent (and hence scale) specified in the map file. If you eg. zoom in, the pixel values are not valid any more. So I set the map extent before queryByPoint() to the extent of the current zoom level like $map->setExtent($minx, $miny, $maxx, $maxy); $map->queryByPoint(...); with min/max values taken from the current map extent (I take the values from the session id). This way it really takes the tolerances in pixels and the query produces the expected results.

I'm attempting to setup a large dataset to be served up via WMS. I have a .tif dataset of approximately 2000 .tif files totalling around 160k pixels by 375k pixels. Each tif image is 5000 x 5000 pixels. My workflow is as follows: create overviews for each .tif image. for each image in dataset addtiffo "file.tif" 2 4 8 16 32 64 Now, I have used gdaltindex to create a shapefile containing all of the .tif files for quickly identfying which tiles need to be accessed for a given bbox. gdaltindex shapefile.shp "path_to_tiffs/*.tif" So far, so good. I'm having good luck using getMap requests to retrieve subsets of the entire bbox. A request for a bbox that is the extent for 1 tile works great, as do larger bbox's. Based on the amount of data read by the mapserver.exe process, I can tell that it's using the overviews properly and not reading the entire source .tif file(s). When I request the entire bbox for the dataset, the mapserver.exe process runs for about 8 minutes and then seems to crash or error out or something. I don't know nor can't find any logfiles to see what is happening. Has anyone had any success dealing with datasets of this size? If so, how have you implemented them? Any help/advise would be greatly appreciated.

However, you really don't want mapserver to have to open 2000 TIFF files to build a single map result. The normal approach is to have two layers, one with the tileindexed set of full data. The other with a low res overview in one file. Use MINSCALE and MAXSCALE to make the low res overview kick in at some point. There are various techniques to generate the low res overview.

Also, as Frank and I just realized, there can be a significant penalty for having the raster LAYER projection different from the MAP projection. Recent (last night) changes improve this, but are not in any released mapserver versions. So, if possible make your raster projection your output projection.

From the sounds of it you are using Windows, and in Windows 2000 a single process can't access more than 2GB of memory. For anything higher than 2GB, you either need Win2K AS or WinXP with the /3GB memory tunning. But with each, you need to run a small binary called (IIRC) imagecfg.exe against the executable file that is being run. That will enable what's called '3GB memory tuning'. Their is a knowledge base article about Windows and Memory... http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx shawn From m.tomko at PGRAD.UNIMELB.EDU.AU Thu Oct 13 17:44:24 2005 From: m.tomko at PGRAD.UNIMELB.EDU.AU (Martin Tomko) Date: Fri, 14 Oct 2005 10:44:24 +1000 Subject: data export tool In-Reply-To: <931f8ea90510130831s51a74bc6o100b46f643af74d1@mail.gmail.com> Message-ID: Thank you Frank (I was hoping for your reply, seems like you are always the person to ask things like this :)) I need to create my dataset (fast vectorization), and I am ready to chose whatever format is best to do this as fast as possible.

Referring to trying to get raster data on a differente projection than layer's one, we've being having problems trying to get together 3 raster layers, with a couple of MrSID Landsat Mosaics each one. Layers are on UTM on 3 different but contiguous zones, south hemisphere, and we tryed to get them on EPSG:4326 : It doesn't worked at all. Each one by itshelf reprojects well, but together we got nothing. We're tryed same but with north hemisphere mosaics and everything worked fine. Any clues or may be a king of strange bug?

We have been having a similar problem. We used PHP/Mapscript to deal with TIFF images. Both for the generation as well as for the reading we sometimes hit PHP's maximum-execution time. The maximum configured value is 2 minutes, but since most proper renderings are done after a few seconds rendering time this huge ammount does not appear resonable. We suspect a bug in either mapserver or one of the associated libraries, but we haven't hunted it down yet. Our temporary workaround has been to convert the TIFF images to georeferenced PNGs and then using these.

After realizing that # ldd ogr_GRASS.so didn't mention the grass vector library I remembered that I had linked just the grass libraries needed by gdal. On the other hand the makefile I obtained with: ./configure --with-gdal=/usr/local/bin/gdal-config --with-grass=/usr/local/grass-6.0.1 doesn't include any -lgrass_vect, so I put it myself just to try. After that ldd ogr_GRASS .so did complain about libgrass_vect. I linked it, and after some more links and incluiding -lgrass_dbmidriver in the LIBS line of the Makefile I have ogrinfo working properly: # ogrinfo /var/www/grass5_mapserver/spearfish60/PERMANENT/vector/streams/head Warning 1: GRASS warning: GISBASE enviroment variable was not set, using: /usr/local/grass-6.0.1 INFO: Open of `/var/www/grass5_mapserver/spearfish60/PERMANENT/vector/streams/head' using driver `GRASS' successful. 1: 0 2: 1 Thanks a lot for your suggestions. I am still working on my other problem (mapserver not showing GRASS raster files that gdal can read) I tried to gdal_translate the spearfish soils layer to pcraster and reading it with mapserver (ugly colours but it worked) so it seem that grass-gdal connection works and mapserver-gdal also works. And now I have changed the roads layer definition in the map file to read the roads grass layer instead of shape (I'm workig with spearfish demo): LAYER NAME roads TYPE LINE STATUS DEFAULT DATA /var/www/grass5_mapserver/spearfish60/PERMANENT/vector/roads/head TOLERANCE 5 LABELITEM CAT_ID TEMPLATE /var/www/grass5_mapserver/spearfish/roads.html # OFFSITE 0 CLASS NAME "Road" COLOR 80 80 80 LABEL POSITION CC SIZE SMALL COLOR 0 0 225 END END END but I have a prettty similar error message # /usr/local/mapserver-4.6.1/shp2img -m /var/www/grass5_mapserver/map-script/mapserver.map -o mapa.png msDrawMap(): Image handling error.

If you write a CGI script that does a bit of preprocessing and then calls Mapserver, you can support all forms of the type extent (and support additional dimensions if desired). Parse the TIME argument, then include parameters in the QUERY_STRING that correspond to replaceable values (%value%) in your mapfile. Your mapfile will need to specify an appropriate value for METADATA wms_timeextent so that the GetCapabilities response will include the proper extent, but as far as I can tell that value is just a string that is sent as-is by GetCapabilities and does not suffer from the same limitations as the TIME value in the GetMap request parameter. Regarding data every 01, 11 and 21 day of the month: because many WMS clients have poor support for time[*], you might have best success enumerating each value explicitly in a comma separated list. 2005-01-01,2005-01-11,2005-01-21,...,2005-10-11 It would also be legal to say 2005-01-01/2005-10-01/P1M,2005-01-11/2005-10-11/P1M,2005-01-21/2005-09-21/P1M but many clients might choke on that list of interleaved ranges. -Jeff DLB [*] We should have made it more clear in the specification that "optional for dataset" does not equal "optional for client." -Ed.

'wrap' is implemented as an integer value. 32 is the character code for ' ' in most of the ENCODINGs. For UTF-8 and US-ASCII the following table might help you: http://www.fileformat.info/info/unicode/block/basic_latin/utf8test.htm The code for '-' would be 0x2d. I guess | $layer->set('wrap',0x2d); should do.

Message-ID: MapServer Users, We're hosting the next Meeting on Tues the 18th of Oct. (next week) We've planned out a demo at the City of Saint Paul of our latest incarnation of MapServer Based Web Services/Data distribution application. * The application is XML/DHTML based with an emphasis on allowing the dataset owners free rain over their repective datasets with regard to updating. * Each layer in the interface has it's own administrator and each admin can edit the data as frequently or infrequently as they like. * Each data layer also uses it's own layer config and Map file which each admin has control over. The look and feel of the layer can be edited by each admin with this configuration. * No one layer being mis-configured can bring down the whole of the service as a result of this type of architecture. * Since the datalayers are seperated and called seperately, they can be used for other Clients besides a Web Browser. The plan now is to start around 5:00 PM. and go for an hour or so. Someone on the List suggested heading out afterwards to socialize. We can pick a place now, or wait till then. The location will be the 7th floor of the City Hall Annex. in Downtown Saint Paul, across 4th street from City Hall. 7th Floor (Computer Services) 25 West 4th Street, City Hall Annex. Saint Paul, Mn. 55102 The door to the building locks automatically around 5:00 pm. So showing up a little early might be best. If you do get stuck outside, just call me at 612.598.9210 Bob Basques.

MINSCALE is the largest scale that the layer will be rendered at, MAXSCALE is the smallest scale that it will be rendered at. This is a bit confusing if you are used to cartographic conventions (i.e., MINSCALE would be the smallest scale). There was a good post by Ed McNierney on how the scale is calculated based on the display at little while ago, it helped us calculate what scales to use (a belated thanks to Ed). Ed's posts are available at: http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0208/msg00056.html http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0211/msg00186.html Greg ---------------------------- From ed at TOPOZONE.COM Fri Oct 14 12:27:28 2005 From: ed at TOPOZONE.COM (Ed McNierney) Date: Fri, 14 Oct 2005 15:27:28 -0400 Subject: Problem trying to serve large .tif dataset Message-ID: Brent - It's OK to break the rules - just as long as you know you're doing it . Frank made another point which is also important, but less-often discussed. At a certain point pyramids/overviews begin to break down because a large image requested at a small scale ends up reading a large number of very small files. If you're opening more than a few files to serve an image request, things will slow down, and if you start reading from hundreds of files you're in trouble. The time to render the image will be dominated by the raw file-to-file seek time of your disk subsystem. Since finding a new file and opening it is one of the slowest things you can do in an application server, your performance gets very bad very quickly. At a certain point you need to take your tiled overview files and merge them, creating a smaller number of larger files. Very broadly speaking, it's probably a good idea to strive for image files whose extents are in the range of several times the size of the output images generated. If you're making 1,000x1,000 output images, and your files are 4,000x4,000 pixels, then (a) most image requests will be served by only opening one file, (b) a reasonable chunk of any file opened is used, and (c) you'll never need to open more than 4 files to render an image. If your files are shrunken overviews that are 100 pixels each, then your 1,000x1,000 image may require up to 121 files being opened, and will never require fewer than 100! - Ed Ed McNierney President and Chief Mapmaker TopoZone.com / Maps a la carte, Inc. 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 ed at topozone.com (978) 251-4242 -----Original Message----- From: UMN MapServer Users List [mailto:MAPSERVER-USERS at LISTS.UMN.EDU] On Behalf Of Brent Fraser Sent: Friday, October 14, 2005 10:50 AM To: MAPSERVER-USERS at LISTS.UMN.EDU Subject: Re: [UMN_MAPSERVER-USERS] Problem trying to serve large .tif dataset Glen, As Frank has pointed out in his reply (and Ed has said for several years), the answer is to pyramid your data.

Brent ----- Original Message ----- From: "Ed McNierney" To: Sent: Friday, October 14, 2005 1:27 PM Subject: Re: [UMN_MAPSERVER-USERS] Problem trying to serve large .tif dataset Brent - It's OK to break the rules - just as long as you know you're doing it . Frank made another point which is also important, but less-often discussed. At a certain point pyramids/overviews begin to break down because a large image requested at a small scale ends up reading a large number of very small files. If you're opening more than a few files to serve an image request, things will slow down, and if you start reading from hundreds of files you're in trouble. The time to render the image will be dominated by the raw file-to-file seek time of your disk subsystem. Since finding a new file and opening it is one of the slowest things you can do in an application server, your performance gets very bad very quickly. At a certain point you need to take your tiled overview files and merge them, creating a smaller number of larger files. Very broadly speaking, it's probably a good idea to strive for image files whose extents are in the range of several times the size of the output images generated. If you're making 1,000x1,000 output images, and your files are 4,000x4,000 pixels, then (a) most image requests will be served by only opening one file, (b) a reasonable chunk of any file opened is used, and (c) you'll never need to open more than 4 files to render an image. If your files are shrunken overviews that are 100 pixels each, then your 1,000x1,000 image may require up to 121 files being opened, and will never require fewer than 100! - Ed Ed McNierney President and Chief Mapmaker TopoZone.com / Maps a la carte, Inc. 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 ed at topozone.com (978) 251-4242 -----Original Message----- From: UMN MapServer Users List [mailto:MAPSERVER-USERS at LISTS.UMN.EDU] On Behalf Of Brent Fraser Sent: Friday, October 14, 2005 10:50 AM To: MAPSERVER-USERS at LISTS.UMN.EDU Subject: Re: [UMN_MAPSERVER-USERS] Problem trying to serve large .tif dataset Glen, As Frank has pointed out in his reply (and Ed has said for several years), the answer is to pyramid your data. This means constructing layers at different resolutions, then setting MINSCALE MAXSCALE for each of the layers in the map file. The goal is to improve the performance of Mapserver by limiting the number of files it has to open to render a requested image. For example, I've set up a site to render the NASA's Geocover global Landsat mosaic. To handle the range of requests from full resolution (14 meters per pixel) to full world-wide coverage (20km per pixel), I set up six levels (and I may add one more) of the pyramid (view in a fixed-pitched font such as Courier): Largest Number of Tile Lvl: Map Scale: Resolution: Tile Size: Pixels: Tiles Size Total Size: Format: ---- ---------- ----------- --------------------------- ---- ---- ---------- ----- ----------- ------ 6 1: 50k 14 meters 1:250k-ish (1/16 of 5x6 deg) 10k x 10k 14064 26mb = 338 gb ECW 5 250k 50 meters 1:250k 1 deg H x 2 deg W 2k x 2k 14921 3mb = 38.4 gb ECW 4 1m 200 meters ~1:1m 5 deg H x 6 deg W 3k x 2k 36x60 = 2160 20mb = 26.1 gb TIFF 3 5m 30 sec ( 1km) 15 deg H x 30 deg W 2k x 3k 12x12 = 144 20mb = 2.4 gb TIFF 2 20m 2 min ( 4km) 45 deg H x 90 deg W 1k x 2k 4x 4 = 16 10mb = 0.167 gb TIFF 1 100m 10 min (20km) 180 deg H x360 deg W 1k x 2k 1 = 1 7mb = 0.007 gb TIFF Disclaimer: The above is just an example of pyramiding a large raster dataset (tuning by adding levels or adjusting scale will likely be required). And I've broken Ed's Rule #3 ("For best performance, don't compress your data") since levels 5 and 6 are ECW, and Rule #4 ("Don't re-project your data on-the-fly") since levels 4,5,6 are in UTM.

Most commonly this is caused by (1) incorrect connection string (2) you didnt specify a 'user=...' in your connection string (3) the postmaster (postgresql server) isnt running (4) you are not allowing TCP/IP connection to the postmaster (5) your postmaster is not running on the correct port - if its not on 5432 you must specify a 'port=...' (6) the security on your system does not allow the webserver (usually user 'nobody') to make socket connections to the postmaster (7) you forgot to specify a 'host=...' if the postmaster is on a different machine (8) you made a typo I have proven to change localhost for 127.0.0.1, but the result is the same one. postgresql this being executed, because if I put netstat - na appears: TCP 127.0.0.1:5432 LISTENING I don't know which is the problem.

In-Reply-To: <434F1B6B.6050000@dmsolutions.ca> Message-ID: Thanks! At least I now know I didn't just do things wrong and understand why some things worked and others not. From the website this is not at all clear as it gives the impression time series as in point 2 can be served... It would be really great if option 2 is supported. Very much in line with what Jeff wrote, I foresee problems with our map client as well as with others when I start specifying the time series following option 4, although it would be an elegant way of describing the time series :-) Option 2 will be excellent for many of our temporal data series. I'll be happy to test, but have to add that I'm traveling in the coming two weeks, so its hard to reply directly. Looking forward to a solution! On one more note: I noted the way time series in WMS and WCS are defined is different (according to the samples I used). WCS uses an index file that is added as a separate LAYER, while WMS can directly use the index shape file. I'm not sure (yet) a WCS time series can be defined in the same way a WMS can be, but it might be once solution 2 works for WMS!? Otherwise, would there be a way to hide a LAYER completely from a WMS so one map file can be used for both WCS and WMS? If my description is not clear, I can post a more detailed explanation later when back in the office. Thanks very much in advance!

The maps are all floating point maps and as you (whoever interested) probably followed in a few mails, the result of most of my maps simply resulted in a single color layer (in my case it was yellow). Frank Warmerdam helped me to solve what was solvable and workaround what was "workaroundable". The following is an extract and resume of the mails exchange. Any reply and correction is appreciated. Alright, the problem was not only one, but a bunch concurring: 1) GRASS novalues are not supported and give problems Running gdalinfo -mm on the map, we find that part of the problem is that nodata values are being treated as "nan" (not a number). GDAL and mapserver do not know how to excluse "nan" nodata values from the min/max calculation so the autoscaling gets all screwed up. Here we can see it in the gdalinfo output: Band 1 Block=385x1 Type=Float64, ColorInterp=Palette Min=0.000 Max=229172.410 Computed Min/Max=nan,nan NoData Value=nan Therefore the min and max have to ge defined and supplied to the map file with the following: PROCESSING SCALE=min max 2) There is a problem with the creation of color ramps in the case of a big number of not homogeneous distributed values: Color Table (RGB with 100001 entries) 0: 0,0,0,0 1: 255,255,0,255 2: 255,255,0,255 3: 255,255,0,255 ... This is why I had a yellow map. The first 256 values of the color table were used by MapServer for the after-scaling values. Effectively the first 256 entries of the color table are all shades of yellow. 3) MapServer does not support the GRASS color rules metadata Metadata: COLOR_TABLE_RULES_COUNT=5 COLOR_TABLE_RULE_RGB_0=1.000000e+00 4.583448e+04 255 255 0 0 255 0 COLOR_TABLE_RULE_RGB_1=4.583448e+04 9.166896e+04 0 255 0 0 255 255 COLOR_TABLE_RULE_RGB_2=9.166896e+04 1.375034e+05 0 255 255 0 0 255 COLOR_TABLE_RULE_RGB_3=1.375034e+05 1.833379e+05 0 0 255 255 0 255 COLOR_TABLE_RULE_RGB_4=1.833379e+05 2.291724e+05 255 0 255 255 0 0 The metadata contains the coloring rules that should be applied. However, mapserver does not currently know how to use this sort of color rule metadata. For now the only solution is to recreate classes that are value similar. One problem though is that MapServer classes don't allow applying a range of color to a range of values like GRASS (or QGIS). Applying own CLASSes in the LAYER makes mapserver ignore the color table. The CLASSes option has two main drawbacks: a) The CLASS does not allow color ranges. There is no big solution (only workarounds), if not to wait on the new range based class coloring that Bill Binko has been working on. An implementation of that is available in 4.6.x but it is under revision. b) If we decide to create a set of CLASS rules to get the map drawn "as if" it was interpolated, you will need to create a lot of rules, which gives big big performance problems in drawing the map. This can however be solved with a PROCESSING command. Here the explanation: The problem is that the class lookup is done once for each "bucket" in the lookup table and that by default there are 65536 buckets. It helps a lot to add the following line in the LAYER definition: PROCESSING "SCALE_BUCKETS=200" This basically alters the resolution of the lookup table but substantially accelerates things. After some testing on what would be the best to do for now, I'm now letting the following bash script snippet for automated creation of the raster part mapfile. It contains the solutions and workarounds reported in this document: # the path to the grass cellheader file absolutepath=$mapsetpath/cellhd/$i echo "LAYER" > rastertmpfile echo " NAME $i" >> rastertmpfile echo " TYPE RASTER" >> rastertmpfile echo " STATUS ON" >> rastertmpfile echo " DATA \"$absolutepath\"" >> rastertmpfile # extract the min and max minmax=`gdalinfo -mm $absolutepath | grep Min | awk -F "=" '{print $2, $3}' | awk '{print $1, $3}'` # extract the gdal computed min and max gdalrange=`gdalinfo -mm $absolutepath | grep "Computed Min" |awk -F "Computed Min/Max=" '{print $2}' | awk -F "," '{print $1}'` # if gdal has problems with colortables and novalues, it is not able to compute the range, # therefore we have to supply it and create a set of ad hoc colorrules if [ "$gdalrange" == "nan" ] then # minmax has the format "123 234", so just extract them min=`echo $minmax | awk '{print $1}' | awk -F "."

Tom, I haven't dug through the previous emails closely to see what is going on, but I thought I should answer this. There has been a substantial improvement in the amount of precision OGR maintains for WKT and GML encodings of geometries. The changes were applied a couple months ago. They are definately in GDAL/OGR 1.3.1 and might be in 1.3.0. OGR spatial filtering will also now use GEOS if built-in.

My script uses a different approach than the previous poster's example.

The script is available under an "MIT-like" license, which basically means you can use it however you like (with only minor conditions). The "wrap_url" script, as I call it, is very easily configured. In most cases, one need only specify the MapServer URL with the "map" parameter, e.g. "http://localhost/cgi-bin/mapserv?map=/path/to/my/map.map". For more general-purpose uses, wrap_url understands relative URLs and also handles redirects. Basic Authorization is also (somewhat) supported (e.g. "http://myname:mypass at localhost/").

Well, it is hard to know from this what version the GDAL is, but it is certainly recently dated. You could try upgrading to GDAL 1.3.1 but it is somewhat of a long shot for fixing the problem.

Sorry in advance if this observation is out of place. So now that I have reminded myself that measuring distance on maps is a difficult matter, I have a further question regarding the distance measuring tools in mapServer (in particular with the use of the Mercator projection). After a little research, the problem regarding measuring distances when using the standard Mercator projection would be a variable issue based on lattitude. This is fairly obvious if we think about the way the Mercator projection works, and perhaps my best solution is to choose a better projection for my area of interest (California - perhaps a version of UTM would give me better measurments - in fact I am reasonably certain it would). But the big questions for me is - since there are errors within the distance measuring tools, do the same errors exist in the scalebar tools?? After measuring a few scalebars and comparing them to paper maps of California it would seem that the answer is yes. All of the scalebars drawn through mapServer are short (using the Standard Mercator between lattitudes 33 and 38). Even though the answer is that there is an error using distances with the Standard Mercator with my system, I am, to say the least, unclear as to where this problem lies . . . PROJ4 problem?? . . . a compile problem?? . . . a GDAL problem?? some other issue???

As Cliff pointed out, if you are interested in measuring distances, a Mercator projection is just the wrong choice of projection. Different projections have different properties; none are perfect, and all sacrifice doing some things poorly in order to do other things well. Again, Cliff pointed out the one prominent reason to choose a Mercator projection - it lets you draw lines of constant compass declination (rhumb lines) as straight lines. Unless you're a marine navigator with a defective GPS receiver, that is probably not useful to you. I have occasionally vented my frustration at the rampant proliferation of the "geographic" projection these days, in which latitude and longitude are used X/Y coordinates. This isn't the same as the Mercator projection, but it's very nearly as useless. You *cannot* create a generalized scale bar for such a map. That's not MapServer's fault, and has nothing to do with a MapServer configuration. You just cannot do it because the linear scale on such a map varies with both the latitude and with the angle of the line measured. It is just plain impossible to create an accurate scale bar. The fact that some maps display a scale bar next to a Mercator projection doesn't mean that scale bar is accurate (although the more honest ones will footnote the scale bar indicating the one place on the map where it's correct). Fortunately, there are many projections in the world to choose from . The UTM family of projections was defined (in part) to provide relatively uniform distance measurements. That's why each UTM zone is only 6 degrees wide; the projection math works fine beyond that range, but the distortion increases to an unacceptable level. That's also why US states have adopted State Plane Coordinate Systems (SPCS). They are designed to cover a smaller area than UTM, but with a smaller degree of distortion, suitable for use in surveying and other professional applications. Many states are divided into several "zones", each of which uses a different (but related) projection, to further minimize the distortion. If you are specifically interested in the State of California, the State GIS program uses an Albers projection for managing statewide data. While nothing's perfect, this projection is probably a good candidate for use in displaying California statewide data sets in a manner that allows distance and area measurements (and scale bars) with a reasonable degree of accuracy over a relatively large area like California.

Dear Martin, as I understand MyGIS and the spatial functions of Mysql 4.1 are two pair of shoes. MyGIS is an older implementaton of spatial functions in mysql but not implemented in the main stream of mysql. We have a project where we fetched x/y data from a mysql database via odbc driver on a debian box (horrable to get the driver runing) but as far as I know there is no way to read mysql 4.1 spatial data directly. I tried to upload the manual to the new mapserver page, but it didn't work - maybe I did something wrong. If that'll help you plese send an email.

I have a drive time analysis that displays isochrone maps you can see it here http://imaptools.com/demos1/?tab=3 This works by computing the isochrones and writing a shapefile with nested overlapping polygons. Each polygon has an attribute that is then used as a CLASSITEM in the mapfile to render it, and I use PHP in this demo to glue everything together. There is some prototype support for color ramps being added to mapserver that would make it easier to define the isochrone color ramps in the mapfile. Do a search on the archives for COLORRAMP should reveal more on that. Hope this helps, -Steve W.

Jos?, This error is typically reported when the computed internal WIDTH or HEIGHT are zero. This might be happening in your case if the BBOX is substantially larger than the extents of the data, such that the final result HEIGHT would less than 1. BTW, I don't think it is legal according to the WCS protocol to request data beyond the extents of the coverage. Are you doing that? However, I am not sure of this analysis. For us to really dig into this I think you will need to provide everything we need to reproduce the problem. o Map file (cut down to just what is needed for this problem). o Data file(s). o the QUERY_STRING we can pass on the commandline to reproduce the problem.

The ovf file has an sql statement that includes something like: Select city as "l'emplacement_de_la_station" etc. Chameleon Query widget (or Mapserver WMS) is choking on that apostrophe. This sort of thing works fine for characters with french accents (e.g. select air1_map_2005.id as "num?ro_de_la_station"), but it's not working with this apostrophe situation. Our solution would be to do something like using another sequence of characters and doing a search and replace in the query widget to get the proper thing. But does anyone know how to fix this properly? Or how to test where the error is occuring? The query works fine in SQL, so I know it's a mapserver or chameleon thing - it doesn't like this character (') in a fieldname. I've tried escaping it (in the .ovf file) using 2 apostrophes '' and I also tried \' but the chameleon query keeps showing No results for the layer. Sorry for crossposting. D.

If so, Mapserver can handle data in disparate projections by reprojecting "on-the-fly": 1. Your MAP's projection ("init=epsg:4326") will be the common output projection. 2. Your LAYER's projection will define the actual native coordinate system of the dataset (One would be UTM the other latlong, etc) If the layer projection differs from the map projection, it will be reprojected everytime you request an image. The reprojection is pretty fast but keep in mind that reprojecting HUGE datasets will slow things down so it's best to preprocess them in that case.

Message-ID: MapServer Users, We're hosting the next Meeting on Tues the 18th of Oct. (next week) We've planned out a demo at the City of Saint Paul of our latest incarnation of MapServer Based Web Services/Data distribution application. * The application is XML/DHTML based with an emphasis on allowing the dataset owners free rain over their repective datasets with regard to updating. * Each layer in the interface has it's own administrator and each admin can edit the data as frequently or infrequently as they like. * Each data layer also uses it's own layer config and Map file which each admin has control over. The look and feel of the layer can be edited by each admin with this configuration. * No one layer being mis-configured can bring down the whole of the service as a result of this type of architecture. * Since the datalayers are seperated and called seperately, they can be used for other Clients besides a Web Browser. The plan now is to start around 5:00 PM. and go for an hour or so. Someone on the List suggested heading out afterwards to socialize. We can pick a place now, or wait till then. The location will be the 7th floor of the City Hall Annex. in Downtown Saint Paul, across 4th street from City Hall. 7th Floor (Computer Services) 25 West 4th Street, City Hall Annex.

I (we, actually) tried your syntax, but neither the backgroundcolor nor the outlinecolor attributes on the label object are color objects, and so attempting to call the setRGB method on them fails with an AttributeError. According to the mapscript API, and introspection of a mapscript-parsed map file in a Python interpreter, those attributes must be set with mapscript color objects. Hence the code I previously listed. I should note that the layer in question is being generated entirely from scratch with mapscript. It is not being modified from a layer that has been read in from a map file. We have learned that this means we have to set all kinds of default values that otherwise appear to be assumed. Having no background, for example, is not the default behavior for a layer generated entirely using mapscript commands. (It is, in fact, a solid black rectangle.) Your suggestion to specify basic values for our layers in a map file and then merely modify them via mapscript commands is an excellent one, however, and definitely would simplify what we're trying to do. For workflow considerations, we hadn't considered it, let alone thought it possible.

I think I'd rather have the code for a layer all in one place, rather than part in a map file and part in a Python script. We've got a base map file that contains the layers all our customers need but we'll have to make additional layers fairly regularly and it seems simpler to keep the customer-specific layers in one place (Python mapscript code) so we can render them selectively. If it's just an issue of figuring out what defaults have to be provided, I think we can work through it. Does this seem like a bad idea for other reasons?

I suspect that you might be doing something like this: class.label = mapscript.labelObj() right? This could be your problem. Instances of mapscript.classObj are **complete**. There is no need to create new attributes for them. A new instance of classObj already has a properly initialized labelObj as a "label" attribute. New instances of labelObj (as above) won't be properly initialized. That's just the way MapServer/mapscript is. Underneath the Python wrapper is a lot of C code which still presumes that we're parsing a mapfile. Here's an example session: Python 2.3 (#1, Sep 13 2003, 00:49:11) [GCC 3.3 20030304 (Apple Computer, Inc. build 1495)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import mapscript >>> c = mapscript.classObj() >>> c.label.minsize 4 >>> c.label.maxsize 256 those are the normal defaults, and will give you working labels. Now, the problematic usage: >>> l = mapscript.labelObj() >>> l.minsize 0 >>> l.maxsize 0 >>> this label is going to fail. Rule of thumb: whenever an object has another object attribute with a single value (such as the label attribute of a classObj), that attribute will be created and initialize by the parent's constructor. cheers, Sean -- Sean Gillies sgillies at frii dot com http://zcologia.com From bruce.tonkin at GOV.BC.CA Tue Oct 18 16:02:35 2005 From: bruce.tonkin at GOV.BC.CA (Bruce Tonkin) Date: Tue, 18 Oct 2005 18:02:35 -0500 Subject: MapServer GetFeatureInfo Message-ID: I have a map service and would like to use the GetFeatureInfo command.

After poking around in the source code for mapServer (particularly the parts using and distance calculations) it became obvious that mapServer uses cartesian coordinates within the framework of the projection for these purposes - hence when using a projection such as the Standard Mercator there will be distance measuring problems . . . Since then I have found a fudge that works for my application, but it is just a hack in PHP mapScript that gives results close enough to what I need. Since mapServer does not try to be a 'GIS' program perhaps this issue will never be addressed . . .

So my observations are: 1. Layer must be queryable="1" using TEMPLATE "foo.html" to use GetFeatureInfo with the info_format=text/plain. This provides all the attributes for the feature queried. 2. To use the info_format=application/vnd.ogc.gml and extract GML only, you need to set DUMP to True. 3. To expand on 2 above, if you add the METADATA tag gml_include_items "all", the GML includes all the other attribution for the feature. In all cases, it appears as if only one feature is returned.

Hexdumpping the files, it is really hard to see the structure at all. The best explanation I have heard is that the lyr is a serialized COM object, which means it will be next to impossible to reverse engineer. It makes one miss the old .avl files and ArcView 3.

I'm trying to think of how it even could- WCS is supposed to provide unfiltered access to raster data (unless resampling is explicitly requested). I can compute a display scale for an image of a certain size but that's a generally meaningless number used for turning stuff on and off. I don't think it is a good way to control the production of large datasets. Is that what you're hoping to use it for? If so I think maximum image dimensions are a better alternative. Steve >>> Jos?

It is really the WMS GetFeatureInfo GML response that I want to suppress the geometry for. WFS should probably always return geometry. This relates to: http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=300 .... and since control of the attributes was done, I was hoping that control of the geometry was too. Many people want to publish WMS services without exposing their geometry. I've always hacked mapgml.c myself to suppress the geometry, and was hoping that this would not be necessary any more.

After reinstalling Mapserver, I am seeing performance that is less than a tenth of what I had before. Server is running Redhat Enterprise Edition behind an Ensim virtual hosting package. I've gone through installation carefully, and I think I have everything right. But when I reinstalled Mapserver I updated several supporting libraries. I want to make sure I'm barking up the right tree. I suspect Apache is the problem. Am running PHP as a separate CGI. What I am seeing when I run "top" is that the PHPCGI processes take over the machine. This didn't happen before. I had a steady system load of about 0.7 and was able to service all requests; now I see a server load of 10-20 (!) and am serving only about 10%. Any suggestions on things to try? Is this slowdown between 1.3 and 2.0 a known (or familiar) problem? Haven't tried FastCGI yet. I really want to understand what has happened, and why, before I inject more changes into the environment.

Or should > I look elsewhere? I always stick with Apache 1.3 Last year we tried Apache 2 for reasons unrelated to mapping, and the httpd would spontaneously freeze entirely. We downgraded to 1.3.x and things were great again. The freezes were happening under extremely light loads and were happening every 1-2 days. So, although I can't say that your performance problems are due to Apache2, I'd definitely recommend installing Apache 1.3 and trying it out. There are (were? please speak up if this is outdated) some thread-safety issues in the various libraries on which MapServer and MapScript depend. And with Apache2's different approaches to multithreading, problems are to be expected. (Although we were specifically using prefork, which I'd think should avoid any threading issues.) -- Gregor Mosheh System Administrator and Head Programmer HostGIS, GIS Hosting Solutions for the Global Community http://www.hostgis.com/ __________________________________ Yahoo!

I have 2 deployments of the same base data that are using the same TT font to produce arrows. Please ignore the difference in background color, but if you look at the attached images, you'll see that there is a striking difference in the boldness of the font from the first .gif to the 2nd. The MS installations are almost identical, but obviously something isn't quite right. I could increase the size of the font on the attachment mapserv2_with_arrows to be able to see the vectors, but that isn't what I want to do. Where should I start digging? GD, MS? I'm using pretty much the latest and greatest versions of everything. But I can list specifics -- just shout it out.

Did you want to do some sort of filtering on the field Tipo? There are different ways to filter data, including using the FILTER keyword in the layer definition. If the text of the argument to the FILTER keyword starts with "WHERE" then it is assumed to be an SQL WHERE clause that should be passed on to Oracle. eg.

The main argument for PostgreSQL with PostGIS is that it scales to many users at once better that MySQL, it is SQL standard compliant, and it maintains data integrity better. But you need to tune it! As installed out of the box it does not run well. Please see the tuning threads in the above archives for more info.

They focus on Postgres/MySQL, without delving into the spatial capabilities however. Also see: http://sql-info.de/postgresql/postgres-gotchas.html http://sql-info.de/mysql/gotchas.html One key factor is that the default install of Postgres is set up to run on minimal hardware, and needs the config file tweaked to make use of decent amounts of memory to perform well. MySQL's default settings tend to suit gruntier hardware, so it is often faster "out of the box". On the spatial side, having spatial functionality as part of the core DB is tidier than a 3rd party plugin like PostGIS, but the Mysql spatial functionality is still being developed, and is currently well behind PostGIS (IMHO). AFAIK, the MySQL query functions only check MBR relationships, which is very quick, but frequently return wrong answers, so are not really much use yet. I suggest you check to see if two separated but neigbouring polygons with overlapping MBR's are considered disjoint or overlapping in MySQL, and also consider whether or not you set up Postgres to use decent amounts of memory after you installed it.

Let's take into consideration a city layer. We use the Query function to see the data associated with the city feature, for example, the name of the city, the population etc. This data is stored in the shapefile. This works fine. Furthermore, I use postgresql as a database. In one database I have a table called "Monuments". For each city, there are several monuments. So the relationship between the city and the monument is one-to-many. Inside MapServer I wish to click on a city, and the result is the information inside the shapefile, and also the monuments found in the postgresql database. Of course, there is the same primary key inside the shapefile table and the postgresql table, that is the name of the city. But How i connect MapServer with PostgreSQL?

There have been posts to the mapserver list about this and I believe that Richard Greenwood has published a paper that discusses this technique. The other way to present one to many relationships, and a method that I have employed recently, is to embed a URLs right into your shapefile so that when a user queries each city, they see the URL and click on that to show the one to many results. The url being one that looks like the one you would have created in the above example. Please do some searches in the list archive on "querying" and maybe you will find examples of these methods. Also - check the mapserver documentation on templates. Hope this helps. D.

You can find pre-built binaries of MapServer built with ECW SDK based JPEG2000 support (and Kakadu actually) in the FWTools package. http://fwtools.maptools.org/ If you are determined to build it yourself then I would suggest you use the ECW SDK 3.3 pre-release source. Email me and I'll provide a link to the source. But the 3.3 ECW SDK should be released properly "pretty soon now".

In my servlet, I have got a MapServerMap object to encapsulate MapScript. I create this object like this: public MapServerMap(String aMapFileName) throws Exception { super(); try { File f = new File(aMapFileName); if (f.exists()) { Map = new mapObj(aMapFileName); } else { throw new Exception("Map file not found: " + aMapFileName); } } catch (UnknownError e) { throw new Exception(ErrorMessages.errCreatingMapServerMap); } catch (Exception e) { throw new Exception(e.getMessage()); } } And I use it like this for instance: public void Zoom(int aZoomFactor) { float x = Map.getWidth() / 2; float y = Map.getHeight() / 2; pointObj point = new pointObj(x, y, 0.0, 0.0); Map.zoomPoint(aZoomFactor, point, Map.getWidth(), Map.getHeight(), Map .getExtent(), null); } After I have done all the panning, zooming, filtering and turning layers on and off I draw the map like this: public String Draw() throws MapServerException { try { /* * Draw the map and return the URL under which it was stored */ imageObj image = Map.draw(); String fn = "map_" + getUniqueID() + "." + Map.getOutputformat().getExtension(); image.save(StringUtils.CheckAndAppend(image.getImagepath(), "\\") + fn, Map); return StringUtils.CheckAndAppend(image.getImageurl(), "/") + fn; } catch (UnknownError e) { throw new MapServerException("Error drawing map."); } } Hope this helps.

Message-ID: All I've tried having a quick look through the archive of the mailing lists, MapServer website but can't seem to find any definitive sources for White Papers / Statistics of MapServer with Hardware. Basically we are looking at setting up a hosting infrastructure which will need to have high level of redundancy and be able to server in excess of 2 million maps a month - very broad but we are still evaluating peak loads etc Our preferred environment will be Linux and using the CGI version of MapServer as this is extremeley robust (well done to all involved), is stateless and has a small memory footprint. Most map layers will be in either Shape or TAB and we can configure the Tile Indexes etc. Can anyone point me to any documents that may have been put together previously? We will pull as much info together as possible with the view of publishing a definitive list / set of documentation on the MapServer website when done. Any help will be much appreciated.

Windows<->Mac OS X Message-ID: Dear people, We are seeing different behavior of MapServer 4.6 on Windows and Mac OS X. On Windows the SHAPEPATH value seems to be ignored for ESRI-grids (not sure about other image formats, although I think the same applied for GeoTIFF). When we specify the full path in the DATA element of a LAYER it works fine. On Mac OS X the SHAPEPATH value is used and only the name of the dataset needs to be set in the DATA element of the LAYER Is there a reason for this inconsistency? Thanks in advance!

If you use too large identifiers Mapserver will not return anything, just a blank page. I was using 16 digit identifiers, which is no big deal in Oracle. However it won't work for Mapserver. It didn't crash or give any error messages, just blank screen. I would have preferred an error message or a crash. BTW, my MS is running on Windows.

Andrea, There was a discussion regarding this sort of things a year,2,3... ago and even a bug filed and closed. But I can't find the bug report now. Maybe someone could restore it from the old bugzilla backups if deemed important.? In the end it was decided that WFS was developed to handle such things but that WFS provided no means of compressing the data during the transfer and effectively bloated the data. I think a few people briefly looked into setting up apache to compress the XML stream to send it across the wire but the problem was that the data was not compressed on the fly, it was more like compress->transmit->decompress (whole WFS result), not in chunks.

Charlton, I'm probably missing something, but could it just be the colormapping due to the background that is making the arrows look different? They appear to be the same size.

Hal, Have you tried running just the mapserv executable without PHPMapscript? Is the mapserv cgi still that much slower than the previous version? If so it's not PHP slowing it down. We are running Apache 2 but are unable to comment on the PHP end.

I think it's great that this is being (has been) addressed. Two closely related issues (I think) are these: A. How are polygon vertices joined? 1) By straight lines in the projection, or 2) as great-circle arcs? Can this be specified in the mapfile? If not, it would be great to have a LAYER-level parameter, something like JOINVERTICES=greatcircle or JOINVERTICES=straightline. The GMT program "psxy" offers such a choice (the -A option). B. When making a selection in the mapserver viewport (via jbox, for example), only the corner coordinates of that box get converted back to the coordinate system of the data, which means that what is selected can be very different from what you see. I wrote about this before. See http://spot.colorado.edu/~braup/MapServer/ for an example of polar weirdness. Has this issue made it to the bug list? I can do that if you guide me on how.

Bruce, Currently a straight line in the output projection is created between the point at which the polygon boundary went "over the edge", and where it came back. This does result in anomolies as we can see a bit in the sample images I provided. The reason something smarter (like great circles or some other way to track the horizon) wasn't done was limited time. The client decided they didn't want to fund that degree of fidelity unless they find the current approach unsatisfactory. > B.

I am aware of this problem, but there has been no effort (other than a bit of thinking) to resolve it. I'm not sure if there is a bug report on this issue or not. You can find info at the following url on how to submit bugs. http://ms.gis.umn.edu/development/bugs/ The case of reprojecting bounding boxes is handled specially via the msProjectRect() (in mapproject.c) and this function already has lots of logic about sampling along edges, and through the rect if some points fail to reproject. But it does not have any logic to deal with special polar issues. If we could force it to use the internal sampling for such cases that would help though not completely resolve the issue. I have included the code in case you would like to skim it and consider possible fixes. There is a wiki area for discussion of "world mapping problems" where I liked to accumulate such issues, but with the wiki locked down now there isn't an easy place to catalog such things.

I am aware of this problem, but there has been no effort (other than a bit of thinking) to resolve it. I'm not sure if there is a bug report on this issue or not. You can find info at the following url on how to submit bugs. http://ms.gis.umn.edu/development/bugs/ The case of reprojecting bounding boxes is handled specially via the msProjectRect() (in mapproject.c) and this function already has lots of logic about sampling along edges, and through the rect if some points fail to reproject. But it does not have any logic to deal with special polar issues. If we could force it to use the internal sampling for such cases that would help though not completely resolve the issue.

I've noticed Charlton's recent messages about other mapfile objects not taking cgi substitution variables, could PROCESSING be one of them? So taking another route, I tried to use the mapfile runtime configuration like: &map_sst_processing=SCALE=31000,33000 and again with the "=" url-encoded &map_sst_processing=SCALE%3D31000,33000 Neither of which worked. Is there any way to dynamically configure the PROCESSING object with mapserv CGI or are we limited to hardcoding it at the moment? -- Matt Perry perrygeo at gmail.com http://www.perrygeo.net -------------- next part -------------- An HTML attachment was scrubbed...

Linux/x86 (1 CPU PIII ~1 GHz) was quite satisfactory, around 1 sec/map (about 100 maps/min), Solaris/Sparc with 2 CPUs (Sun Fire440) was ~2...3 times slower and Solaris10 on AMD (Sun Fire V20z) was ~3-4 times faster than Linux. Taking price and also high reliability into account I would suggest the new Sun Fire X4200 (or two x2100) servers with AMD cpu-s and Linux or Solaris 10 os, this will be also the fastest you can get and it should be sufficent for 2 M maps/month.

However a risk could still exists for those using untrusted WMS servers in their apps, or allowing loading of arbitrary Web Map Contexts in their apps. If you consider yourself at risk then you might want to upgrade to libcurl 7.15.0 or to a patched libcurl version that may be available for your OS. Future maptools.org builds (FGS and MS4W) will be based on the latest version of Curl.

J?chym, I'm not following what is occurring in the code. It appears to say: Create a new & empty layerobject named $newLayer then create a new layerobject named $newLayer by cloning it from an existing layer named $layerObj and from there it because a bit more confusing as none of the operations seem to initiate values for $newLayer. There was a recent discussion that may help explain what 'new' objects have defaults and which don't: search the october archives for 'Problems translating map file layers to mapscript'.

CLASS NAME "Cours d'eau" EXPRESSION /Cours d\'eau/ COLOR 0 151 0 SYMBOL "circle" SIZE 5 END Found a solution to part of my problem. Regex helps when dealing with a class expression that contains an apostrophe. I've been trying to deal with the French part of our app, and one of the issues is having meaningful field Names when the user queries in Chameleon. SQL Server / OVF let's you write stuff like: select typ as "type_de_cours_d'eau_?chantillonn?". Mapserver won't let you use this for a classitem. It will if you use %27 for the apostrophe, but then Chameleon query widget doesn't like it. But it's probably not good practice to have apostrophes in field names, so we will have to do a search and replace in our chameleon query widget (2 underscores = ', 1 underscore = space). The other problem was that I needed to classify on something that had an apostrophe in it (e.g. the words "cours d'eau" are in the database). Mapserver doesn't like that in a string expression, but I found out that regex works: EXPRESSION /cours d\'eau/ So - some more solutions to the difficulties I was having. I just didn't know where my problems were occuring - in the OVF, in Mapserver, or in Chameleon. Turned out to be a bit of SQL Server (it really shouldn't let you put quotes into a field name, postgresql doesn't) and handling everything in Mapserver and chameleon. Hope this helps someone else.

Bruce, Currently a straight line in the output projection is created between the point at which the polygon boundary went "over the edge", and where it came back. This does result in anomolies as we can see a bit in the sample images I provided. The reason something smarter (like great circles or some other way to track the horizon) wasn't done was limited time.

You can find info at the following url on how to submit bugs. http://ms.gis.umn.edu/development/bugs/ The case of reprojecting bounding boxes is handled specially via the msProjectRect() (in mapproject.c) and this function already has lots of logic about sampling along edges, and through the rect if some points fail to reproject. But it does not have any logic to deal with special polar issues. If we could force it to use the internal sampling for such cases that would help though not completely resolve the issue. I have included the code in case you would like to skim it and consider possible fixes.

Frank, A few folks have run into this in the past, but I don't recall the details. I think it was fixed for the 4.6 release. I see that you are running MapServer 4.5 which was the "development" version of mapserver between 4.4 and 4.6. I think if you upgrade to 4.6 (or better yet our current development 4.7!) the problem should go away.

Bruce, Currently a straight line in the output projection is created between the point at which the polygon boundary went "over the edge", and where it came back. This does result in anomolies as we can see a bit in the sample images I provided. The reason something smarter (like great circles or some other way to track the horizon) wasn't done was limited time.

This is part of the SLD WMS spec. The response of a WMS DescribeLayer is: a) the onlineresource of a WFS (or WCS for raster layers) b) the name of the typename With this info, you could request more info from the associated WFS, mostly WFS DescribeFeatureType will be useful for that. It will give you all the attributes and most likely (depending on the implementation) also an idea of the geometry type. Note that something was changed in Mapserver 4.6 which makes it ouput a gml abstract featuretype by default, which won't give you an idea of the geometry type. Note also that WMS GetFeatureInfo could give you a rough guess of the geometry type, and the list of attributes in the GML returned. But it is specific to a point clicked in the map. Mapserver also gives back a geometry on the WMS GetFeatureInfo (which you could check for point, polygon or line in the string), but most WMS's don't give back the geometry on WMS GetFeatureInfo. Anyway, you can see it's not straightforward.

I come from an ESRI ArcIMS environment and I expected that getting the layer's geometry type should be one of the basic easy things to do. I understand that some implementations does give this info, but surely this should be part of the basic OGC standard? Maybe there is a good reason that this is not included and would love to hear it! Anyway, thanks for the trouble.

I see that you are running MapServer 4.5 which was the "development" version of mapserver between 4.4 and 4.6. I think if you upgrade to 4.6 (or better yet our current development 4.7!) the problem should go away.

In particular, I think you will find you have to do some hand editing of the makefile to force use of static versions of libraries. You will also likely have to recompile some of the dependent libraries yourself to get static versions. For libraries like libpng and libz that almost certain to already be on the server, you could likely leave it as a dependency on the external shared library. Everything else should be static.

In-Reply-To: <000b01c5d969$30884e80$041410ac@comune.lugo.ra.it> Message-ID: I have done this, making a large number of the dependencies static (freetype, gd, proj, gdal) but it was not fun and it took a lot of work editing makefiles. There is no easy way to do it, and you have to make sure that every library you do not expect to find on the target system is included. This can be extra fun with things like freetype, that are not a direct mapserver dependency, but rather a dependency of a dependency. Some things (like zlib) are sufficiently standard that you can often assume they will be available dynamically.

In-Reply-To: Message-ID: hi list, I'm also having problems with mapserver or mapscript dying on certain antialiased lines. I think I tracked the bug down to gd, I still have to find the time to find out in what cases it happens. For those interrested, for me gd segfaults for me in file gd.c on line 3055, because it is called with out of bounds values for pixel position. the call is being made on lines 3098 or 3119, with the argument (y>>16)+1 (line 3098) or (x>>16)+1 (line 3119) which seems to me to be out of image bounds. My fix is to set the clipping regions of lines 3069-3071 to 1 pixel inside, which is a quick workaround which prevents the segfaults, but produces poor quality for short line segments. cheers, tb On 10/26/05, Flavio Hendry wrote: > hi Abe > > as said, I had problems with it (hanging mapserver). and the ones which > seemed to work, I did not see a difference (was using jpeg as output). > png24 is no option, resulting size of images too large. > > Mit freundlichem Gruss / Best Regards > Flavio Hendry > > ---------------------------------------------------------------- > TYDAC NEWS http://www.tydac.ch/german/index.php?menu=News_actual > ---------------------------------------------------------------- > ############ Mit freundlichen Gruessen / Kind Regards > ############ mailto:flavio at tydac.ch > ############ TYDAC AG - http://www.tydac.ch > #### #### Geographic Information Solutions > #### #### Luternauweg 12 -- CH-3006 Bern > ############ Tel +41 (0)31 368 0180 - Fax +41 (0)31 368 1860 > ---------------------------------------------------------------- > > > -----Original Message----- > From: Abe Gillespie > To: MAPSERVER-USERS at LISTS.UMN.EDU > Date: Tue, 25 Oct 2005 12:11:00 -0400 > Subject: Re: [UMN_MAPSERVER-USERS] antialiasing line features.. > > > Hey everyone, > > > > Sorry, a somewhat OT - This thread has piqued my interest a little. > > Would someone mind posting examples of aliased vs. antialiased > > images? > > I'm just curious about the results you can get. > > > > Thanks! > > -Abe > > > > On 10/25/05, Dylan Beaudette wrote: > > > On Oct 25, 2005, at 2:54 AM, Flavio Hendry wrote: > > > > > > > Ciao Giorgio > > > > > > > > It might not be the antialiasing but the png24. png24 files tend > > to get > > > > very large, i.e. 400k compared to 70k as a JPEG (check your > > output > > > > directory).

But what do you want to know? They can be seen mostly as separate tools (although you could use Mapserver WMS layers in OpenEV if you wanted too). OpenEV can be used for displaying and analyzing data, which can help in the first stages of a Mapserver project. Or you could use it e.g. to write a pre-classified Geotiff version of your raster. Tyler Mitchell's O'Reilly book discusses both Mapserver and OpenEV.

Message-ID: MAPSERVER-USERS Digest - 24 Oct 2005 to 25 Oct 2005 (#2005-309)Thanx Flavio to reopen a subject that I investigated more than 1 year ago and pushed me to re-check the situation with newer relases of Mapserver and GDAL. Though the Jpeg outputformat is much lighter than the Png24 I experienced a problem with truetype point symbols. I don't know why but with the jpeg outputformat they are shown in a very poor quality. Instead using the same mapfile, just changing the outputformat to Png24, the truetype symbols are perfect. The Jpeg quality doesn't influence this behaviour, even if i set it to 100 it's the same. So if I want perfect symbols I have to set the outputformat to png24 but in this way the file is much bigger. Otherwise I have to renounce the truetype symbols and use only the other types of point symbols. Is this a limitation of the Gdal libraries? For what regards the line antialiasing I noticed, though not measuring it, that the performance is strongly affected by the use of a cartoline line symbol even if the outputformat is set to Jpeg. The antialiasing is an interesting feature and the desktop systems (ex. Manifold) that uses a good antialiasing engine really have a very attractive look but, depending of the project goals, this feature could be considered of secondary importance compared to performance, especially in case or many remote accesses and not so fast connections such as in my country.

Giorgio (or Flavio), If you can submit a bug, to my attention, demonstrating the difference in output quality between jpeg and png24 I could look into it.

Claire has built a Google map based system, getting locations from IP addresses. I suggested a fully Open Source based system might be appropriate, and could even be a OS GIS suite showcase (applications and global raster & vector data) if anyone wanted to take it that far. Postgres/Postgis/mapserver seems the obvious mix, though I admit it is not the only one. ka-map could also fit in there... as well as plenty of other OS web-mapping related packages. A small minority of Postgres users seem to use spatial data, and this could present & foster a Postgres based solution for anyone interested in adding location functionality to existing Postgres implementations. So, is anyone out there in OS GIS world interested in becoming part of a team to help put this together?

The Chameleon all then takes that URL and automatically appends a ? to the URL, you can not have two ? marks in a URL. The only solution I know of would be to create an alias in Apache for your map... ie http://10.59.36.53:8080/cgi-bin/mapserv?map=/var/www/html/fgs/apps/chameleon -2.0/test/map/test.map &typename=sightings2004_point becomes http://10.59.36.53:8080/cgi-bin/maptest then it will work great.

Of course, this will add another maintenance task by having to empty the image dir from time to time, depending on the usage. Luis J. Villanueva-Rivera, B.S.

And a cookie, once set in your browser, is re-sent in *every* request to the origin server, giving even casual sniffers plenty of opportunities to grab your passwords. Finally, even if your network traffic is secure, you need to be aware of the kinds of cookies you use. Session cookies are fairly safe, since they vanish when you close your browser. Persistent cookies are more dangerous, since they will be stored in some browser-specific way that may be easy for others to view. If you don't like the idea of storing your passwords in plain text files, then you should not want your browser to do essentially the same thing in its cookie-store.

Frances, PostGIS IS slower than shapefiles because: 1) You have to make a network of local connection to the database which include some kind of authentication. 2) You have to do a query to fetch some data 3) The data needs to be transformed from its native PostGIS format into whatever mapserver uses internally 4) all the data has to packaged up into packets to transfer from the server to the client (mapserver) 5) probably other stuff too So why would anyone want to use it? Well you can do lots of cool GIS like things with it. You data might be stored there for other purposes, like it is bing dynamically updated by other process. You need to do thematic mapping, etc, etc Should you put all or any of your data in PostGIS? Depends on your need. If all you data is static data and you are only display maps of it then probably not. Use shapefiles as they are most efficient. You can take a hybrid approach of having some static layer in shapefiles and some other layers in postGIS. If you are doing queries the only look at a small percentage of the data then postGIS queries can be optimized maybe to speed things up. If you are just recalling all you data when zoomed out maybe you need another layer where the data in simplified for that. -Steve W. http://imaptools.com From e108727 at METU.EDU.TR Thu Oct 27 11:55:16 2005 From: e108727 at METU.EDU.TR (Serkan Girgin) Date: Thu, 27 Oct 2005 21:55:16 +0300 Subject: list of default layers Message-ID: Hi!

I'd have to see the interface to be sure. But it is likely that you are telling the software to recenter 2 ways. MapServer gives priority to the click-based nav. You can fix this a couple of ways: 1) use a second form on the page for the coordinate nav so that no conflict exists, it might look like this in your template:
lon lat
The only problems with this approach is that the layers are set when the page loads so if the user changes them and then sets a point those changes are lost. Secondly, your design might not allow you to setup a second form like this. 2) when you submit the form, check the values of form vars called lat and lon using javascript and if they look valid then craft a call to mapserver using those values. Like so (assuming the form is named 'ms'): function submitMe() { if(document.ms.lat.value && document.ms.lon.value) window.location.href = '/cgi-bin/mapserv?map=[map]&scale=[scale]&layers=[layers_esc]&mapxy=' + document.ms.lon.value + '+' + document.ms.lat.value; return true; // submit as normal } This approach is the most flexible but requires javascript. I would use lat/lon for the form element names to avoid any conflct with standard MapServer parameter names. This is off the top of my head but the code above should get you started.

Sounds like this task should be solved using WMS and WFS services. Google is cool but in order to foster both Open Source and standards (OGC) we would suggest to use e.g. MapServer as WMS to produce the maps and GeoServer as WFS to manage geomtries. Those OWS services could then be included in any OWS client, web interface, etc. Everything is there and ready to go, the effort to get it to run should be minimal. Our clients usually operate PostgreSQL databases with several million geometries - those 500 to 600 markers could be hosted on any antediluvian box and still be fast. You will know what to about mirroring, we would probably suggest to implement P2P - read Ward Cunninghams ideas int he keynote at the Wikimania conference this summer... We have done the user mmapping Mapbender users with tooltips, direct link to the website, etc. You can have a look at it on the project homepage http://www.mapbender.org Its done Wiki-style so that users can enter their own position (use the blue flag) or remove or edit any position (use the i-button). No user accounts yet but security and authentication is in place and have just not yet been necessary (still waiting for spatial spam...) We will spread word about spatial data management using PostgreSQL/PostGIS with MapServer, GeoServer etc. at the http://www.opendbcon.net (database fundamentals) on Nov. 8. and 9. in Frankfurt/Main, Germany. This idea is on short notice but i would be really very excited if i could show the map there! We suggest the following alterantive actions: - It should be easy to add a geometry_column to the existing PostgreSQL database which alredy has the positions. Add a GeoServer WFS to access the geomtry and a MapServer for WMS display. - Alternatively send Paolo or us or both the geo-positions and we add them to our existing OWS infrastructure (that will takt a few hours of work only). Beause there is not so much time until the conference this would just be be a prototype which should in the long run move to the PostgreSQL or PostGIS homepage or Wiki or both. Yet another idea: Mediawiki (the Wikipedia software) is also right now introducing geometries to the Wiki database - obviously also using PostgreSQL/PostGIS. This would be another cool multiplier.. and there we also meet with Google again.

GDAL/OGR 1.3.1 is the latest version and it is suitable for use with MapServer. However, you can't just substitute in different version GDAL DLLs with MapServer because MapServer uses the OGR C++ API which is quite fragile. That means if you want to upgrade to a recent GDAL/OGR you will need to get a rebuilt MapServer as well. My understanding is that Assefa is now providing MapServer+PHP4 builds with GDAL 1.3.1 (as of quite recently), so you might try upgrading to that (from maptools.org). I am not convinced that this newer version will resolve your problem but there has been quite a few improvements since the version you are running. If you want to check, you might just want to try rendering your map with the "shp2img.exe" from FWTools. If that works properly then you will know that upgrading is worth the trouble.

Frans, My understanding is that PostGIS connection times are very fast so FastCGI is unlikely to give much benefit. However, if you have many PostGIS layers in the map, I would encourage at least using the CLOSE_CONNECTION=DEFER processing option to ensure the same connection is used for all the layers. This does not require FastCGI. FastCGI basically just allows preserving the connection from cgi request to cgi request. > Also, I wonder if PostGIS would improve relative to shapefile if you > have many concurrent users requesting the same data... I am dubious about that. The operating system will already preserve the shapefile data in RAM from request to request. I would think that PostGIS would pay off in speed in cases that shapefiles don't optimize well, for instance if you want to filter out most data based on an attribute column, that could be done very fast in Postgres. Other than that, as folks mention Postgres' big benefit is flexability of data integration and updatability.

I'm not an "expert" on this but it seems from previous posts that the connection for postGIS/postgres is very small and does not benefit significantly from FastCGI which adds a lot of complexity to the infrastructure. > Also, I wonder if PostGIS would improve relative to shapefile if you > have many concurrent users requesting the same data... Both postGIS and shapefiles have to access disk files, both (assuming they are setup correctly) have spatial indexes. shapefiles just have less overhead so if the application is just straight get the data from the stores and render it, shapefiles will be faster. As soon as you need to do joins and spatial operations or more complicated stuff in postGIS you get an advantage. In many cases you just can NOT do it with shapefiles, like thematic rendering based on a join. So a hybrid approach works best for me. Most of my layers are in shapefiles for speed and a few are in postGIS for functional features of that environment. The best thing to do is make some tests based on your application. You should do that anyway to check the performance tuning and identify the bottle necks to performance so you can tune those for better performance. -Steve W. > Regards, > > Frans > > Stephen Woodbridge wrote: > >> Frances Collier wrote: >> >>> Hello, >>> >>> >>> >>> I?ve been trying to find out what exactly Mapserver gets back from >>> Postgis when querying the tables.

Then in the attribute table of the spatial index I would set a 100, 200, and 400 value according to the appropriate layer on a field named "res". Finally, in the mapfile, I'd create one raster layer with three different classes filtered according to CLASSITEM "res". Each class would in turn have the appropriate MAX and MIN scales.

Ideally, we'd just want to have a static map with possibly Javascript popups. That way, the performance can be good and the web site doesn't become that onerous that the pg www group kicks us out. So, a question to you and Palo: Can you generate such static map (along with Javascript code) from Mapserver?

The code could easily extended to work from lines but I've not taken the time to make that happen. Assuming you're extracting the linear feature from a dataset (e.g. a shapefile) then a featurequery is what you want. If you want to use an adhoc line then you'd want to do an nquery with either the imgshape or mapshape parameters holding the line. Sounds like test you're doing should work. I use feature queries all the time. What type of feedback from the software are you getting when you try your tests? Steve >>> Rick S 10/28/05 12:19 PM >>> I am using the Mapserver CGI. My goal is to determine all the polygons in LAYER_A that a line passes through. Currently, I have an application that will successfully return the polygon(s) that a specific point is in (using MODE=NQUERY). Now I want to take it to the next step and use a multi-segment line instead of a single point. I have been trying to do this using the FEATUREQUERY and FEATURENQUERY modes that use an SLAYER (Type POLYGON) with a single FEATURE object that contains the points that make up the line (arranged as a closed polygon). I haven't been having much luck getting the FEATUREQUERY to work though. Before I spend more time with this, can anyone tell me if I am heading down the right path? Is there an easier way?

Running it from a console (we run using linux), you would type: shp2img -m [path to mapping file]. If you have any errors in your map file, shp2img will complain, otherwise it'll spit a bunch of gibberish to your screen for you (actually an image printed out to console, but for now all you should need to worry about is whether or not it can actually create an image from your map file). This should give you a hand in determining if the problem lies in your map file or your webpage.

In-Reply-To: <435FD708.7080002@svs.gsfc.nasa.gov> Message-ID: Hi! Happy to see this discussion and implementation progressing! This (seeing more clients & servers with time support in WMS) is indeed very true. We are working to get temporal data online both as WMS and WCS. Having a good support for that in MapServer would be a real asset, and actually allow us to use MapServer also for these data sets. In fact, this also gets to the problem I faced so far while implementing this; One common Map file will not do to have both a WMS and WCS with time support running, they are slightly different in the way they have to be configured (the WCS needs special layer that gives an error when accessing the service as WMS, at least that is what I ran into when following the different WMS and WCS time examples). Are there plans to align the two services?

My only other comment is that your creation of a new colorObj that is bound to style.color is superfluous. Remember, a styleObj already has color members, so you can simply do this: style = mapscript.styleObj(class) style.color.setRGB(255, 0, 0) It's too bad that the mapserver-users list is completely walled off from Google -- the only search engine that matters anymore -- it seems that I'm doomed to repeat this advice about style colors forever.

This is my s= etup: Imagery format - MrSID Resolutions - 100, 200, and 400 Is there a built-in way to handle multiple resolutions like this? My idea would be something to the effect of building a spatial index (with gdaltindex) for all three resolutions into one shapefile. Then in the attribute table of the spatial index I would set a 100, 200, and 400 value according to the appropriate layer on a field named "res". Finally, in the mapfile, I'd create one raster layer with three different classes filtered according to CLASSITEM "res". Each class would in turn have the appropriate MAX and MIN scales. Can this be done? If not, is there a way to accomplish this as a single layer? Also, is there an authoritative place online where I can find information on displaying MrSIDs in MapServer (tutorials / references)? As always, thanks for the help. -Abe Abe, There is a MrSID gdalpluign for ms4w1.0.1 . I have never gotten it to work, so I extracted the MrSIDs to TIFF.

Tamas, msAddImageSymbol() calls fopen() and then passes that file handle to gdImageCreateFromPng(). The gd function is in a different DLL and if either bgd.dll or libmap.lib are built with the default C library on windows, it will be unable to utilize the file descriptor opened in mapsymbol.c. Normally I avoid this by ensuring I build with the C runtime library which can be accomplished by using /MD. You also have to ensure that bgd.dll is built with a compatible runtime library. I think the normal bgd.dll is built with VC6 so you would need to use VC6 for mapserver as well. I actually thought we had restructured mapserver to avoid passing file handles to the GD png (and gif, and jpeg) functions to avoid this issue, but apparently it exists in at least this function. I would encourage you to file a bug report on it, and someone can fix it. In case that someone might end up being me, please include a minimal map file that will demonstrate the problem as I don't imagine I normally go through this function.

Jacob, I'm not sure why this is happening, it is not a common behavior. If you can boil this down to a simple mapfile, and raster dataset that can demonstrate this problem with a particular shp2img call then I would encourage you to submit it in bugzilla, and assign it to me. Normally mapserver does a variety of sampling along the request edges in an effort to get all the data needed. The only obvious reasons I could see for such a failure is if the projection transformation is failing for that corner.

The user should be enabled to select one, several or all layers out of a set of 15 Layers. Every layer contains the same geometry: about 400 Polygons, not too complex; the corresponding shp-file is about 1000 kB, and drawing the shapefile with mapserver overlaying it 15 times takes less than a second. First I tried accessing the attribute data which is stored in a MySQL-Database via the OGR/ODBC driver, and performance was very weak (app. 10 sec.)(the join fields where indexed). Then I tried by moving my data completly into a Postgis-based system (I also built a spatial index): performace got better, but it still takes roughly 5 sec to get a map, just drawing 15 Postgis-stored layers without any filtering or table joins and so on. The application runs on a P3-800 Mhz with 512 MB RAM and Windows 2000/Apache System (well, not really fast, but should be sufficient since it has to handle only one request a time?). I would greatly appreciate if someone could give me an idea what could be wrong with my application - thanks a lot in advance!

I will certainly use CLOSE_CONNECTION=DEFER if I use PostGIS. But regarding the difference in performance between PostGIS and shapefile, doesn't the indexing PostGIS/PostgreSQL can do count for anything? For large datasets, you need a spatial index. I understand that the native shapefile driver (which is the recommended way to access shapefiles according to the MapServer Reference Guide for Vector Data Access (http://www.maptools.org/dl/docs/mapserv/MsVectorDataGuide.pdf)) does not support ESRI's spatial index for shapefiles. OGR, on the other hand, can use a spatial index (see http://www.gdal.org/ogr/drv_shapefile.html). Better still, it also supports an attribute index. An attribute index could be used by MapServer if a layer has a classification based on attribute values. I really don't know how MapServer reads and sorts its data, but I can imagine an attribute index will be beneficial for layers with symbolization based on attribute values. Still, if I understand correctly, the attribute index that OGR uses can not be used if a classification based on value ranges is wanted. So is it really true that shapefiles always outperform PostGIS data, even if we are talking about big datasets with classifications?

OGR, on the other hand, This is true BUT mapserver has its own spatial index. See the utilities shptree and every *.shp should have an index *.qix find /pat/to/data -name \*.shp -exec shptree {} \; will add the spatial indexes in Linux. > can use a spatial index (see > http://www.gdal.org/ogr/drv_shapefile.html).

Other than the spatial index mentioned above mapserver does not use any other indexes like for attribute joins. Once you know what entities spatially overlap the map it cycles through all of them and renders each in turn so there is no need or benefit for other indexes. PostGIS is needed if you want to do thematic maps because a join is required is usually require to generate the theme CLASS column. > So is it really true that shapefiles always outperform PostGIS data, > even if we are talking about big datasets with classifications? Yes, unless you require a join for rendering or need to filter out a lot of data from the file/table. -Steve W. > Regards, > > Frans > > > > Frank Warmerdam wrote: > >> On 10/28/05, Frans Knibbe wrote: >> >> >>> An interesting thread. >>> Shouldn't the connection step go faster if you have FastCGI enabled in >>> the MapServer? >>> >> >> >> Frans, >> >> My understanding is that PostGIS connection times are very fast >> so FastCGI is unlikely to give much benefit.

The currently very limited implementation of attribute indexes for shapefiles in OGR is just for looking up unique values for joins. > So is it really true that shapefiles always outperform PostGIS data, > even if we are talking about big datasets with classifications? No, PostGIS can have better performance for operations that require filtering on attribute columns.

I'm having a bit of trouble displaying a shapefile in UTM33-format properly together with my maps that use polar stereographic projection. I've made a small perl-program (included below) that creates two shapefiles, one with the same projection parameters as my map, and one in UTM33. Both files simply contains one point for every fifth latitude and longitude. I also have a map of Norway as a shapefile in UTM33. When I plot my basemap together with the two point layers, and the shapefile of Norway, the stereographic point layer matches the latitudes and logitudes of the basemap. The UTM33 point layer has an offset that seems to grow the further south you get. The shapefile of Norway seems to have pretty much the same offset as the UTM33 point layer Here are some examples: http://crusaders.no/~trondmm/mapserv/utm_vs_stere.png http://crusaders.no/~trondmm/mapserv/utm_vs_stere2.png http://crusaders.no/~trondmm/mapserv/utm_vs_stere3.png red dots = stereographic point layer yellow dots = UTM33 point layer Now, after some experimenting, I've found out that I can get the two point layers to overlap completely, if I change the stereographic shapefile to use the WGS84 ellipsoid. Unfortunately, my basemaps depend on a spherical earth, and it's not possible for me to convert them. So - is there anything I can do in the mapfile to get mapserver to get the layers to overlap more precisely? Here are my projection parameters from the mapfile: The Web object: PROJECTION "proj=stere" "lat_0=90" "lon_0=0" "lat_ts=60" "a=6371000" "b=6371000" "units=m" END The stereographic point layer and all basemaps: PROJECTION "proj=stere" "lat_0=90" "lon_0=0" "lat_ts=60" "a=6371000" "b=6371000" "units=m" END The UTM33-point layer and shapefile of Norway: PROJECTION "proj=utm" "zone=33" "ellps=WGS84" "datum=WGS84" "units=m" END and here's the program I used to generate the point layers: --8<-- #!/usr/bin/perl use strict; use warnings; use Geo::Proj4; use Geo::Shapelib ':constants'; my %proj = (stere => Geo::Proj4->new(proj => "stere", lat_0 => 90, lon_0 => 0, lat_ts => 60, a => 6371000, b => 6371000, units => "m", ), utm33 => Geo::Proj4->new(proj => "utm", zone => 33, ellps => "WGS84", datum => "WGS84", units => "m", ), ); while (my ($name, $proj) = each %proj) { my $shape = Geo::Shapelib->new(); $shape->{Shapetype} = POINT; $shape->{FieldNames} = [qw/POS LAT LON /]; $shape->{FieldTypes} = [qw/String:64 Double Double/]; for (my $lat = 0;$lat <= 90; $lat += 5) { for (my $lon = -30; $lon <= 30; $lon += 5) { my ($x, $y) = $proj->forward($lat, $lon); push @{$shape->{Shapes}}, {SHPType => POINT, Vertices => [[$x,$y]] }; push @{$shape->{ShapeRecords}}, ["$lat $lon", $lat, $lon, ]; } } $shape->save("shapetest_$name"); } --8<-- -- Trond Michelsen From warmerdam at POBOX.COM Mon Oct 31 07:41:22 2005 From: warmerdam at POBOX.COM (Frank Warmerdam) Date: Mon, 31 Oct 2005 10:41:22 -0500 Subject: Getting UTM and stereographic projections to overlap In-Reply-To: <20051031143507.GR20103@crusaders.no> Message-ID: On 10/31/05, Trond Michelsen wrote: > The stereographic point layer and all basemaps: > > PROJECTION > "proj=stere" > "lat_0=90" > "lon_0=0" > "lat_ts=60" > "a=6371000" > "b=6371000" > "units=m" > END > > The UTM33-point layer and shapefile of Norway: > > PROJECTION > "proj=utm" > "zone=33" > "ellps=WGS84" > "datum=WGS84" > "units=m" > END Trond, I have you considered misrepresenting the UTM data as being on the spherical earth as well to avoid PROJ.4 trying to apply an ellipsoid translation? eg.

Agneta, It looks like you are trying to build against the GDAL "build" directory rather than where it was installed. This is not normally supported. In this case the linker used by mapserver is complaining that it does not understand the format of the .la file, a "libtool" thing. I would suggest ensuring you do a "make install" in the GDAL build directory, and then using the gdal-config that gets installed, likely /usr/local/bin/gdal-config.

Message-ID: Patrick: To my knowledge, there is no "out of the box" authentication system for MapServer, so it's up to individual applications to implement it. I have put an "enhancement" request into Bugzilla for simple MAP-level authentication for MapServer CGI: http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1512 Of course, there's no guarantee that anyone's actually going to implement it! Since MapServer doesn't (yet) have this feature, you can still configure your web server to protect the MapServer CGI program itself, with Basic Authentication (for example). This would force all users of the MapServer CGI to provide valid credentials on every request, regardless of the map file specified. This could be acceptable if yours is the only application on the server that uses MapServer. Another alternative is to implement a CGI "wrapper" that does the authentication checks before passing valid requests along to MapServer. Incoming requests to the MapServer CGI that do not come through the wrapper would have to be rejected, but I'm not sure how this would be accomplished. Perhaps the wrapper would set an environment variable that the web server uses in a conditional statement that allows or denies access to the MapServer CGI, depending on the existence of the variable. I hope this gave you some ideas.

The easiest way to fix this problem is to replace gdImageCreateFromXXX to the corresponding gdImageCreateFromXXXCtx in the mapserver code. I have posted a bug as a reminder for it to http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1513 I have compiled mapserver and the related libraries using Visual Studio 7 and I don't think it is a good idea to back out to VS6 as to eliminate the need to recompile the GD library. However to create a working nmake makefile for MSVC seems to be a great adventure so I would be pleased if anyone had a suitable solution and shared it with me.

My question is that as far as i can tell, there is no way to do a similar method using remote WFS services. To clarify, i am not after MS as a WFS Client (eg. render the WFS response as an image) but simply forward the response on to the client. For example, 1. Client (WFS Request) --> Core Mapserver (Forward request) --> Remote Mapserver 2. Remote Mapserver (GML Response) --> Core Mapserver (Forward request) --> Client I hope mapserver could be enabled as a sort of pseudo OWS "proxy" but I have had a look around without much success, Ideally, if there was a new meta tag such as "wfs_response_method" "GML" or something similar attached to the layer, then this would suit my purpose exactly. Since the response is currently stored as a GML file in the ms_tmp directory anyway, it seems a simple manner of just forwarding on the request instead of rendering it using GDAL/OGR.

So in summary, on your middle tier you would have a WFS Client layer in your MAP file, and you would also expose your middle tier as a WFS server using the appropriate wfs server metadata.
