Everytime I perform an nquery on the layer I get two extra results in my template. Has anyone ran into this issue? I think I have the mapfile defined correctly, so I believe it might be an issue with the shapefile. Does anyone know what in a shapefile would cause this to happen? It is just a shapefile of roads and it appears to be fine (no extra records) when using it in ArcView. I have done many applications using nquery in the past and never ran into this issue before.

I currently use the Rosa Applet as the map window display. My application is very similar in behaviour to the Mapserver Atlas application (AKA gmap) (online: http://www.mapsherpa.com/gmap/gmap75.phtml). Whenever the user hits 'Redraw Map' or clicks on a tool button, it causes the whole pages to be refreshed. My question is how could this be changed so that only the map window is refreshed, not the whole page? I know this is an architectural type question which is not really related to Mapserver, but if anyone would know the answer it would be the people on this list.

The map projection is Lambert Conformal and the WMS layers are in Geographic projection(epsg:4326). The map covers Northwest Territories in Canada and the difference between Geographic and other projections is really noticeable here. The result returned by the function is in the right projection but the coordinates X,Y seams to be off and for WMS layers that are Point type I never get a hit when I query, for Polygons is a better since I can zoom enough to get a good result. If the map is the same projection as the WMS layer the function return a correct result and I can query without problem. Is this a known issue or I?m missing something?

The layer geometries usually are rectangles with 4-5 vertices, when the map is draw the geometry is re-projected but the lines are straight lines with no curvature and the image is really ugly (some big trapezoids ? is the same image as the one generated by Spatial Advisor in Oracle if I would transform the geometry using the epsg of map). On the other hand if I get the same layer and converted in a shape file, than loaded into my map file, the image is re-projected nicely with curved lines. I cannot use shape files in my map, I?m stuck with oracle spatial and I was wandering if there is any way to get the same image for oracle spatial as I get for shape file. Thank you in advance.

I've had a look through the bug tracker and source, the main difference between msPOSTGISLayerRetrievePK() between 4.8.1 and 4.10.2 appears to be the following (mappostgis.c revisions 1.66 to 1.77): * Revision 1.71 2006/05/03 22:35:41 pramsey * Added schema separation and search path awareness to the LayerRetrievePK. (towards Bug 1571) Does anyone know if this is a known issue? Is the schema patch likely to be the source of it? - I can usually get two or three maps before the application server dies completely - We're using the Java mapscript swig bindings - Postgres 8.2 with PostGIS 1.2.0 - The segfault occurs with 4.10.0 and 4.10.2 - I have not had a chance to see if the CGI version has the same problem - Reverting to 4.8.1 on the same system works fine, suggesting it's not a Postgres/PostGIS issue - Stack trace included below Thanks, Antti Roppola Stack: [0x6f395000,0x6f408000), sp=0x6f4033c4, free space=440k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) C [libc.so.6+0x68055] strncpy+0x35 C [libmapscript.so.4.10.2+0xcf5ae] msPOSTGISLayerRetrievePK+0x8e C [libmapscript.so.4.10.2+0xd0b18] C [libmapscript.so.4.10.2+0xd1694] msPOSTGISLayerWhichShapes+0xd4 C [libmapscript.so.4.10.2+0x84f2b] msLayerWhichShapes+0x5b C [libmapscript.so.4.10.2+0x91c79] msDrawVectorLayer+0x1c9 C [libmapscript.so.4.10.2+0x920da] msDrawLayer+0x8a C [libmapscript.so.4.10.2+0x934d1] msDrawMap+0x1d1 C [libmapscript.so.4.10.2+0x464e5] Java_edu_umn_gis_mapscript_mapscriptJNI_mapObj_1draw+0x35 j edu.umn.gis.mapscript.mapscriptJNI.mapObj_draw(JLedu/umn/gis/mapscript/m apObj;)J+0 j edu.umn.gis.mapscript.mapObj.draw()Ledu/umn/gis/mapscript/imageObj;+5 v ~StubRoutines::call_stub ------IMPORTANT - This message has been issued by The Department of Agriculture, Fisheries and Forestry (DAFF).

URL: From williams at WEBSAWYER.COM Tue Jul 3 23:32:49 2007 From: williams at WEBSAWYER.COM (Doug Williams) Date: Wed, 4 Jul 2007 00:32:49 -0600 Subject: phpmapscript imagemap creation Message-ID: Rodrigo, Here is what I did to make the imagemap work using phpmapscript. This is my first go round trying to create an imagemap, so others may have more sensible methods or more extended methods, but I never did get any specific information from anyone, nor could I find any complete information about FORMATOPTIONs which would be very helpful!!. I had to feel my way through trying to piece together bits and pieces of scattered information, found luckily by google searching which turned up one interesting old message from the list from someone that also did not have it working. I never did find any response to that person that showed a working example. Anyhow, I have also not ever tried to describe this process so bear with my rambling, long-winded description. First I added a OUTPUTFORMAT to my mapfile. I already had one OUTPUTFORMAT in my mapfile to improve the quality of images generated by mapserver. Whichever OUTPUTFORMAT comes first in the map file is used when generating images, unless the script resets this, which has to be done in order to generate both the imagemap (which is not an actual image, but just some html code) and the map (which is the actual visual image that is displayed). It would be possible to use more than one mapfile rather than resetting the outputformat used, but it is not necessary. More on outputformats in a minute. Also it is necessary to define a CLASSITEM for the layer that you want to use to define your imagemap. The classitem is the attribute that is stuffed into the html and displayed when the mouse is held over map polygons (in this example, a simple one layer example). The other important connection between the map file and the script is that the image shown in the html output has to be the same dimensions as the IMAGESIZE defined in the map file. The other necessary steps take place in the php script. So hear is the mapfile stuff: OUTPUTFORMAT NAME imagemap DRIVER imagemap FORMATOPTION "MAPNAME=map_test" FORMATOPTION "TITLE='' # this gets stuffed properly, you do not need to reference anything # on the right side of the = sign # in fact, you do not need this option at all. But maybe # someday you will? MIMETYPE "text/html" # this option is also not needed! END OUTPUTFORMAT NAME jpeg DRIVER "GD/JPEG" MIMETYPE "image/jpeg" IMAGEMODE RGB EXTENSION "jpg" FORMATOPTION "QUALITY=100" END The first output format is used to generate the imagemap, the second is used to generate the actual map. The script resets the format that is used. Show you that in a second. I don't really think the mimetype statement is necessary, but I have seen it used so I include it here. I myself will actually end up using the FORMATOPTIONs for mouseover and mouseout shown in my earlier message, but I am not going to go into how I am going to take good advantage of them here because it will apparently be necessary for me to do some additional coding to get the effect I want, which I find works much better (immediate response on the web page with more inclusive attribute data detail), but is more complicated programmatically... more scripting on the server side and a script on the client side as well which is not needed with this method. I won't describe the second output format, but the first defines a reference name for the outputformat; the driver which tells mapserver what to generate in terms of output, in this case the html code defining the areas of the imagemap with the coords; the name of the generated , you use this name when declaring the usemap; and the formatoption to add a title for each defined area of the imagemap which is stuffed with the attribute data from the shapefile specified by the layer classitem (not really needed). (Don't formatoption suppress="yes", or you will not get the areas in your .) So hear is my layer definition in my map file: LAYER NAME "lakes" # this is a bad layer example because the polygons are small and so # the imagemap driver generates some bad areas. I'll process these out. # Typically one would likely be using this with maps that produce # larger features than a few worldwide lakes that are being squished to mere dots # in an image the size and way I am doing here. DATA esri/world/lakes STATUS on TYPE polygon CLASSITEM "NAME" # this is the attribute field to list in the 'title' for each area CLASS NAME "Lakes" COLOR -1 -1 -1 OUTLINECOLOR 200 200 50 END END Well, it is something like that anyway, but the important part is the CLASSITEM line, which tells the imagemap driver what information you want stuffed in the map area title. Again, the title formatoption above is not even needed, the imagemap driver just stuffs the classitem values into the title for each area. It would be much nicer if all the attributes were made available with a reference mechanism so that one would have to declare something like formatoption "TITLE=[NAME]" with a way to escape characters like quotes ... maybe that is coming in the future. The map file will also have the SIZE defined, such as: SIZE 600 300 which we will use in the script to define the width and height of the image returned to the browser. So those are the mapfile necessities. Easy enough. The php script is not so bad either. If you have created and displayed a map, then you know how to create your map object for creating the actual map: $map_path="/path/to/mapfile/directory"; $map_file="mapfile.map"; $map = ms_newMapObj($map_path.$map_file); You may want to create another map object to deal with the imagemap, though you could just use the same object. $imagemap = ms_newMapObj($map_path.$map_file); I draw the imagemap first, and the imagemap driver is set first in my map file, so draw() is using that driver. It will be necessary to change this to the jpeg outputformat before drawing the other map (or png or gif or whatever you may be doing): $htmlmap = $imagemap->draw(); $htmlmap->saveImage("/path/to/someplace/the/script/can/write/test.html", $imagemap); This will generate a text file on the server. test.html will be the: with areas and coords and titles I use the php require() command to write this into the html that I return to the browser. To change the ouputdriver use the phpmapscript command: $map->selectOutputFormat("jpeg"); and draw as before: $image=$map->draw(); $image_url=$image->saveWebImage(MS_PNG,1,1,0); I have mixed jpeg and png here ... probably not what you want, png is better for vector/line type stuff, jpeg is better for more real world type images (in my understanding). So now you have an image of your map as before, and you have the imagemap information in a file that was written to the server. I add the imagemap to the html output like this: I just plop it in right after I send the html tag. Then you need to display the image in an tag. The standard mapserver way is to place the image in a form tag, but I have not tried this as I read stuff stating that imagemaps do not work in form elements (makes sense since there is no place to associate the needed usemap). Fortunately I had already moved away from displaying my images in those elements because I wanted to be able to click on the map without sending the form automatically. Not using the form element means you will have to send the img.x and img.y coordinates that get sent automatically when using the form element by some other method, but that goes beyond the scope of this discussion. So display the image like this:

usemap="#map_test" width=width; ?> height=height; ?> border=0> or however you like to code. If things turn out correctly, when you place the cursor over a polygon and leave it still for a couple of seconds, the title will appear by the cursor showing you the attribute data. View the page source to see if the looks like what you expect it to look like. Those are the basic pieces. Sorry it is not a very well laid out description. If you have any questions, feel free to ask. I am using a slightly more recent version of mapserver, but believe this has been around a while. If the mapserver folks would like, I would be willing to produce something more in line with some of the howtos.

I've had a look at the code and I could spot line 1770 of mappostgis.c (Mapserver 4.10.1, line number might vary slightly in other versions) which doesn't really look very effective: length = (int)pos_sep + strlen(pos_sep); Casting a pointer into an int doesn't seem to make any sense here. I'd suggest you change that line to length = strlen(pos_sep); recompile and try again.

First of all my setup: - Centos 4.4 - apache 2.0.52 - php 5.1.6 - postgresql 8.1.8 - mapserver 4.0.1 (I know, I should update mapserver, but having to rebuild all the legends in our system and possibly avoid some other side effects would be a major headache and have so far kept me from doing this) - gdal 1.4.0 - postgis 1.2.1 - geos 2.2.3 - proj 4.5.0 - glibc 2.3.4-2.25 The error in the httpd error_log reads as stated in the subject. I have added some multipolygon data that I had previously obtained by converting it from a shape file using shp2pgsql. The odd part about this error is, that I use the same syntax in the map file as for a working multipolygon layer that I had imported using older versions of postgis etc. and the older data works just fine. I have reimported said working data from the original shape file and compared it to the existing data in the working table. the_geom and other relevant stuff is identical. And still the newly imported data produces this error. I have checked projection, db access privs and just about everything else that crossed my mind as playing a part to no avail. So, is this problem a known issue? What else could I try/look into? Any advice?

I'm serious that taking the time to try to explain to you what I was finding did help me to understand what was going on. I do not understand how you were trying to reproduce what I was doing. I did not know the map SIZE had three components. I thought that the docs indicated that there was just a width and height to the size (in pixels). Perhaps that is why you could not reproduce my results. Best, On Wed, 04 Jul 2007 09:03:45 -0400, Yewondwossen Assefa wrote > Doug, > > Sorry for the late answer.

Message-ID: Hi all, We have a Visual Basic application in which which users manually georeference by clicking on some control points & assigning lat's/long's to each. The program then plots GPS positions on this background, & has zoom/pan controls. It is used to capture seabed observations in real time while watching a live video stream from an underwater camera. It is now running on a LAN with a mapserver WMS, and we'd like to use this as the map background provider, instead of the local image. This background is generated from multibeam bathymetry data collected in an immediately prior run over the survey site. Can anyone offer some advice as to the best way to embed such a WMS client in VB? Ideally I guess a dll with zoom/pan & local point overlay capabilities.

Thanks again. > Tiger data is not so good for routing; It does not contain any data about one way streets or intersection controls (i.e. no left turn etc). Some intersections shown on tiger data are not even an accurate reflection of what's on the ground; Things like freeway overpasses that don't physically intersect with the road being crossed appear as intersections in the tiger set. As far as I am aware, for accurate routing you will need to purchase a commercial data set. Remember that tiger was initiated for census work, and the data has limitations when you try and bend it to other uses.

Churchill) Date: Thu, 5 Jul 2007 08:20:03 -0400 Subject: trouble with attribute query Message-ID: I figured out the problem I was having. It has to do with having underscores "_" in the text field. If I replace my underscores with hyphens "-", my query works. This seems to be an odd character for Mapserver to weed out but that appears to be what is happening. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Hi All, I'm having trouble executing an Attribute Query when I base the query (qitem) on the "filename" field in my shapefile. I can choose any other field and supply the appropriate qstring and everything works fine but when I use the filename field I get a "no matching records" found error. The text in the long string in the address bar of the browser IS complete and DOES match the value in the shapefile. Perhaps the text values in the shapefile field are too long for MapServer or special characters like the "." or "-" are causing a problem ? Can anyone confirm or deny either of my theories about this or point to any other possibilities ? The qstring is ... p016r032_09-09-1986_lt5_doc.img The qitem is "filename" and it is a text field. The entire query string in the address bar is ... http://localhost/cgi-bin/mapserv.exe?qlayer=landsat_4&myitem=landsat_4%2Cfilename&qstring=p016r032_09-09-1986_lt5_doc.img&map=C%3A%5Cms4w%5CApache%5Chtdocs%5Cimg_browser%5Cimg_browser.map&program=%2Fcgi-bin%2Fmapserv&mode=itemnquery&qitem=filename The error is ... msQueryByAttributes(): Search returned no results.

I have two issues, if I haven't worn out my welcome . . . * I am pulling 10 different types of observations from this particular buoy. I have listed them all as the same offering and each LAYER has an identical GROUP -- so they all show up nicely under ndbc_44029. The problem is, when I have more than 4 or so SOS LAYERS, whether or not they are part of the same group, I all of a sudden get an empty .xml. And Apache logs show nothing. I know for a fact that there is not a problem w/ the LAYER definition because it's just a matter of cutting and pasting to change from something like a wind_speed column to wind_speed_of_gust. Is there some kind of SOS limit in a *.h somewhere? * Secondly, is there a trick to the TIME element? Here is a working request: http://sos-web.tamu.edu/sos-cgi/madis?service=sos&request=GetObservation&ver sion=0.0.31&offering=ndbc_44029&format=application/com-xml&observedProperty= http://marinemetadata.org/cf%23sea_surface_temperature And it does say it recognizes a timePeriod, but when I tack on a time parameter, it bombs w/ 'msSOSGetObservation(): SOS server error. Invalid time value given for the eventTime parameter'. I dug around in the code, and it still doesn't shed any light on where the problem is occurring. The getcaps behind all of this is here: http://sos-web.tamu.edu/sos-cgi/madis?service=sos&request=getcapabilities&ve rsion=0.0.31. I do plan on writing up how I have gotten this far, so it may help someone in the long run, too. Many, many thanks.

For that to work you need smarter software on the client. The basic issue is that MapServer enforces square pixels and as a result it may change the requested extent to match the requested image size. You have no way to get both the new extent and the image back in the same request. Actually you do using a template to return the computed extent and the created image, e.g.: img:[img] extent:[mapext] but it's nicer to use MapServer as just an image engine. Solutions like MapBender, OpenLayers, MapBuilder, Ka-map and others manage extents on the client and send the appropriate requests for images to MapServer, a WMS server or whatever. I use dbox here and it manages the coordinates in javascript and sends requests to MapServer (mode=map) so that it doesn't have to adjust extents and it becomes easier to just modify the map itself. Here are some examples: - http://www.dnr.state.mn.us/waters/csg/index.html - http://maps.dnr.state.mn.us/waters/csg/station_mapper.html?mapxy=481573.570471947+4900561.10653818&scale=100000&id=39101001&layers=roads+bdry_munipy3+wsh_hunitpy3+sites+strm_baseln3+shdr_clrim3+lakes - http://www.dnr.state.mn.us/hunting/moose/zones2007/zone_report.html?map=/usr/local/mapserver/apps/faw/moose/moose.map&mode=itemquery&qlayer=zone_query&qstring=zone_id%3d25 - http://maps.dnr.state.mn.us/tools/dbox-dev/example/example_fullscreen.html (flaky in IE6) In all of these the maps update, not the page. Anyway, lot's of choices!

An annotation layer in your map file is like a points layer, then add how many shapes than labels. In your code you must only move the $layer->addFeature function into the for() block: for ($i = 0; $i < count($pointlist); $i++){ $labelpointObj->setXY(100+($i*2),100+($i*2)); $labelLineObj ->add($labelpointObj); $labelshp = ms_newShapeObj(MS_SHAPE_POINT); $labelshp->set("text", $pointlist[$i] ); $labelshp->add($labelLineObj); $LabelLayerObj->addFeature($labelshp); } I hope it's working for you ciao ..............................pg -- Pietro Giannini Bytewise srl - Area GIS 41?50'38.58"N 12?29'13.39"E On Gio, Luglio 5, 2007 23:52, joerg pfeiffer wrote: > Hey Pietro, > > thanks for your help.

The problem persists, but for the purposes of this little .tar.Z I dumped the table to a shapefile. And here is what happens: Doing a GetCapabilities on everything like normal (shapefile where it should be), http://your.box.here/cgi-bin/mapserv?map=/I/love/mapserver/m.map&request=get capabilities&service=sos returns an empty XML just like I promised. Now do one of two things: * remove ANY layer, and you should get back a nice XML doc (this is in keeping w/ what I reported earlier, i.e. this # of layers has sent mapserver over the edge). * or leave all the layers and simply remove the shapefile goodies. The getcaps works fine! Strange. I was surprised that it hit the data source at all for a getcaps. Oddly, something gets a little foobared when doing a getobs against this test dataset, and I'm not sure why. But I'm not really concerned, since it was able to return nice getobs from my real db no matter how many layers I had and whether or not the getcaps failed. Thanks for the help, guys.

The first thing I noticed is that the action of your form is wrong. Your form action looks like: action="http://cgi-bin/mapserv.exe" and it would look like: action="/cgi-bin/mapserv.exe" Also in the "map" and "imgext" parameters the values seems to be wrong (but I think this will seem ok when you access the php file through Apache): If you still have problems ask me again.

However idea is that u could collect relevant values from user interface (the web page) which u need to build a new map (for example the list of layers, the current map extent which is returned by mapserver itself in the [mapextent] template variable, ecc...) and build a correct request for mapserver. The list of layers and other key elements for the request, u take via JavaScript with (for example): var layersString = getLayers(); //this call a function which cicle on the layers list and takes only those the user want. imgext = document.getElementById("imgext").value; imgbox = document.getElementById("imgbox").value; //setted by dbox/jbox imgxy = document.getElementById("imgxy").value; //setted by dbox/jbox Than u build request for Mapserver, for example: http://localhost/Scripts/mapserv.exe?map=D:/Web/Heidi_Service/HGis/trentino.map&layer=DTM&layer=ECW&imgext=1600000.1 5000123.4 1620003.7 5010567.9&imgbox=143 200 200 255&imgxy=143 200&mode=browse This request u need to pass mapserver cgi without doing a POST, otherwise u have a page reload. For doing this, I have used an Ajax library which, without doing a POST, let me to call a server side (.NET) function from a client side function (JavaScript). So then I do (I'm still in JavaScript) a call like: AjaxMethods.getMap(queryString, retrieveMapImage_callback); This JavaScript function, "invoke" a server side function (with the same signature, but without the retrieveMapImage_callback parameter). Details about how the Javascript function invoke the server side function are managed by the ajax library I used (and if u use other libraries, things will be different), important thing is that there is no page reload in this process. When the result of the server side function, come back to JavaScript, the retrieveMapImage_callback function is invoked. What I do in this function ? It update map elements: document.getElementById("mapwidth").value = res.value.mapwidth; document.getElementById("mapheight").value = res.value.mapheight; document.getElementById("imgxy").value = res.value.imgxy; document.getElementById("imgext").value = res.value.imgext; document.getElementById("legend").innerHTML = res.value.legend; document.getElementById("scale").value = res.value.scale; imgMap.src = res.value.mapImgUrl; imgRef.src = res.value.referenceMap; imgScalebar.src = res.value.scalebar; But how can I have in server side, new values based on the request above ? I use an System.Net.HttpWebRequest (this one is .NET, Java should have a similar method): HttpWebRequest webRequest = (HttpWebRequest) WebRequest.Create(queryString); And what's the response? In the .map file I specified to use a particular template: TEMPLATE "templates/web_template.xml" which is: Normally, when u use Mapserver in cgi mode, u have the html page which contains those template parameters ( [] ). The html page do a POST, mapserver substitute parameters in the page with new values and the page is sent back to the client. Here is different. The template is processed and remains on the server. You parse the response of the HttpWebRequest, and create an object to send to the client (the response to the Ajax call). Then the client update the page as I explained above. With Java, I think u colud use a library called DWR (Direct Web Remoting), which is conceptually similar to the AjaxPro I used (both are free). Note this is only a method I used, but u could do things in different ways (u could study some php framework). Also I used MapServer in cgi mode. Maybe u want to use Java Mapscript, so things will be different. Ciao Piero 2007/7/5, LITTLE Nelson : > > Thanks for your reply it was the only one I got.

Don't use saveWebImage, that does what you describe, returns a URL to the image you create. You don't show coords above so I suspect that saveWebImage does not really utilize the imagemap driver properly. You are not trying to create a web image, just trying to use the imagemap driver to create the w/ areas and coords to enable the imagemap in the browser. All the imagemap driver does is create the information. [In truth, what I state is what I suspect, I am not a phpmapscript developer, and have no connection to mapserver (other than I think it is supercool and promote it wholeheartedly). Assefa let me know that (if I remember right) mapfile.c is the only real source for indepth info. (Thanks Assefa) Look for that if you are able to read through c code. I have not yet had time to dig into that, but will. > I've tried this as well... > > $imagemap_data= $img2->saveImage($map->web->imagepath."/test.html", > $mapoverlay); > This one should write the info to the file test.html.

While I in my example write the file and then "require" it into my html returned to the server, it could have been achieved this way without saving the info to a file, but just sending it straight into the html returned to server. I have not tried this way. It sounds like you are seeing the coords on your web page. If that is true, then maybe this returns the coords without the prefixed and postfixed . If that seems right, try writing , then execute the command as above, then write , and you should not see the coords on your web page, but they should be in the html if you look at the source. I am out of town for a week or so and will have limited access to email. Hope this helps.

Yup. You'd use the query template (the TEMPLATE setting for a layer) to display the URL in the apprpriate context. For example: Or, if the URL is derived from some field/attribute: Is that a good start? Of course, this assumes that you have a query template and that you have click-to-query stuff basically working.

Message-ID: We have been running fine the US Streets data from DM Solutions along with the latest version of Chameleon. I've recently been handed the responsibilities of our MapServer and have the most recent data (2006 SE) from DM Solutions. When I try to use the provided us streets map file, updated with our previous custom layers, I end up with a blank screen and the apache error_log reports a segfault. Is there anyone out there that is using the most recent US Streets data with Chameleon. What did you have to do to migrate from the 2005fe data to the 2006se? Any help would be appreciated. I am able to successfully run the included sample setup that came along with the 2006se map data, so there shouldn't be a problem there. I should note that I am pretty new to MapServer, so I might just be missing something simple. Thanks.

The correct proj4 settings are: +proj=merc +latts=0 +lon0=0 +k=1.0 +x0=0 +y0=0 +a=6378137.0 +b=6378137.0 +units=m Note this is different than using the ellipsoidal equations which would be: +proj=merc +latts=0 +lon0=0 +k=1.0 +x0=0 +y0=0 +ellps=WGS84 +datum=WGS84 +units=m no_defs" I believe that I need to use Mapserver to do this but I have no idea how to go about it. Currently my Mapserver is running fine displaying the data correctly using the GDA94 projection except i had to use a .vrt file to correctly align the raster image which was slightly out of alignment. I have also set up and can call my Mapserver as a WMS (thought having issues with the WMS Layer function in OpenLayers, just displays a white screen but I believe that this is to do with projections) My Mapserver has been compiled with GD, GDAL, GEOS, PostGIS, PHP and proj4. In my mapfile I have defined each layer using "init=epsg:28355" as well as globally defining the map using the same projection. This reason I am trying to do this is because currently I don't think that my projection can be properly imported into OpenLayers and merged with Google Maps.

For that, I think that you should set the projection for each layer to their "source" projection, i.e., the projection that they are currently in. For you MAP, you should set the projection to the destination projection, i.e., the one that you want to re-project into. Mapserver will automatically re-project it for you (I think). That said, I have only used standard projections to do this, for example, I have combined UTM with decimal degrees in the same map with this approach. I do not know enough to say how you go about setting the custom google projection on your MAP object. HTH, Robert This is kind of hard to explain but what I want to do is use Mapserver to project my data which is in the GDA94 projection as shown below: "# GDA94 / MGA zone 55 <28355> +proj=utm +zone=55 +south +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs <>" to a projection that will be able to be properly merged with Google maps (using OpenLayers) which uses a projection something like the following: "Update 4: Agreement frrom Melita Kennedy and David Burrows that Google Maps and Virtual Earth use spherical equations for the Mercator projection. The correct proj4 settings are: +proj=merc +latts=0 +lon0=0 +k=1.0 +x0=0 +y0=0 +a=6378137.0 +b=6378137.0 +units=m Note this is different than using the ellipsoidal equations which would be: -------------- next part -------------- An HTML attachment was scrubbed...

You're suggesting a Transverse Mercator projection on an ellipsoid when the request was for a Mercator on a sphere. I did a little Googling around and while it appears that the 41001 projection is often referred to as "Transverse Mercator", and there are several references to the PROJ definition you mention (+proj=tmerc, etc.), there is a more sensible reference to 41001 being defined in a GeoServer install as: PROJCS["WGS84 / Simple Mercator", GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS_1984", 6378137.0, 298.257223563]], PRIMEM["Greenwich", 0.0], UNIT["degree", 0.017453292519943295], AXIS["Lon", EAST], AXIS["Lat", NORTH]], PROJECTION["Mercator_1SP"], PARAMETER["central_meridian", 0.0], PARAMETER["scale_factor", 1.0], PARAMETER["false_easting", 0.0], PARAMETER["false_northing", 0.0], UNIT["m", 1.0], AXIS["x", EAST], AXIS["y", NORTH], AUTHORITY["EPSG","41001"]] This is more sensible (at least it's a Mercator projection!) but it is still a ellipsoidal rather than spherical projection, so it's not quite right. However, the entire universe of Web-based "geographic" projection fans, stimulated by Google and Microsoft, obviously don't really get bothered when their maps are "not quite right", so I should learn not to be so fussy. - Ed P.S.

It's Perl mapscript. @sites is an array of hash references, $sitesLyr is from the map file: ############### foreach my $site (@sites) { my $site_pt = $$site{'site_loc'}; $site_pt =~s/.*$(.*)$*./$1/; # extract the points x and y my $line = new mapscript::lineObj(); my $siteShp = new mapscript::shapeObj($mapscript::MS_SHAPE_POINT); my $point = new mapscript::pointObj(); my($x,$y) = split(/ /, $site_pt); $point->setXY($x,$y); $line->add($point); $siteShp->add($line); $siteShp->{text} = $$site{'site_name'}; $siteShp->setBounds(); $sitesLyr->addFeature($siteShp); } my $img = $map->draw(); ############# This works perfectly for the usual PNG output map. Using the same routine for a SVG 'image' results in the symbols/markers getting plotted, but the labels are missing. If I switch to a static shapefile for this layer, the labels do appear in the SVG. Is there anything special with SVG output and the 'addFeature' method for layers that I am missing?

There is obviously not a "standard" EPSG code for this projection. Bradley, you need to decide whether you need to serve these WMS images out to the wide world (i.e. clients over which you have no control) or only use them "internally" where you can control both your WMS server and the client. If it's the former, you have a problem, as there is no EPSG code describing the projection you need that seems to be in general usage so your clients can be expected to support it. If it's the latter, you're fine. You can simply pick any number you like that's not already taken and add that line to your EPSG file. It's just a text file. Let's assume you'll pick 41002 (since 41001 seems to be in popular usage, but is wrong). Then you'd add the single text line: <41002>+proj=merc +lat_ts=0 +lon_0=0 +k=1.0 +x_0=0 +y_0=0 +a=6378137.0 +b=6378137.0 +units=m To the EPSG files on your server and on each client. Then you can refer to it as SRS=EPSG:41002 in your WMS requests and you're all set. - Ed > From: Paul Spencer > Date: Mon, 9 Jul 2007 14:55:22 -0400 > To: Ed McNierney > Cc: "MAPSERVER-USERS at LISTS.UMN.EDU" > Subject: Re: [UMN_MAPSERVER-DEV] Projections > > Thanks for the clarification Ed (and for fixing the cross-list- > posting-bug :)).

Thanks to an example from Charlton Purvis found by a search of previous postings on making an animated GIF (modified to use a single layer, changing the filter to select for the data that is in my current time step): http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0304/msg00482.h tml And a Wiki entry from Jeff McKenna about making a copyright notation: http://mapserver.gis.umn.edu/docs/faq/copyright-layer I have the basics, that is, an animated time series, with a statically placed text entry at the bottom (at a map-specific point, rather than a lat lon). However, the annotation layer can only display a single entry, not one that is updated with the time step. I am wondering how to do this, if I can modify the property of the annotation layer, or if I need to create a point of some sort from a dynamic postgis call. I can't seem to set the TEXT portion of the feature via php mapscript. Anyone have any ideas?

PHP/MapScript doesn't provide the TEXT portion of an annotation feature. It's because it's easier to add directly a point on the top of the map. Instead of adding a FEATURE object to the layer, simply create a point object and draw it on the map image. (Following code not tested) // Outside the loop create a pointObj $oPoint = ms_newPointObj(); $oPoint->setXY(1,1); [...snipp...] // Inside the foreach, draw your map without the copyright layer $thislayer->set("status",MS_OFF); $image[$i] = $amap->map->draw(); // Then draw the point on the top of it // Don't forget to remove the FEATURE object in the mapfile // Also you should give a name to your class in the copyright layer // For now, I'll use "CLASSNAME" $thislayer->set("status",MS_ON); $oPoint->draw($amap->map, $thislayer, $image[$i], "CLASSNAME", $filter); $image_url[$i] = $image[$i]->saveWebImage(MS_GIF,1,1,0); [...snip...] The code is not tested, but it should give you a good idea.

Since we've explained that whatever EPSG code you're using is not standard, you need to be sure that it is defined in both the server and all clients. Have you done that? Failure to do so would be an obvious cause of an "SRS error" from the client. Remember that when you change your map file output or your WMS request to a different SRS, you need to change the extent or BBOX parameters, too. In a WMS request the BBOX parameter always uses the units of the SRS used, so you can't just keep the same GDA94 coordinates and expect them to work. If you don't change them, you're requesting a Mercator output image at some random location that bears no relation to your input data, so it is quite likely to give you a white image (since no input data overlaps the requested map area). - Ed From: UMN MapServer Users List [mailto:MAPSERVER-USERS at LISTS.UMN.EDU] On Behalf Of Bradley Mclain Sent: Monday, July 09, 2007 9:12 PM To: MAPSERVER-USERS at LISTS.UMN.EDU Subject: Re: [UMN_MAPSERVER-USERS] [UMN_MAPSERVER-DEV] Projections When I have the custom projection defined in my mapfile and the native projection defined for layers the map does not show up when doing a WMS getmap request, it just appears white.

You have to be able to express the geographic extents of your area of interest in the units used by your desired map projection. Otherwise there's no way you can know what you're asking for. I don't use OpenLayers and can't help you on its configuration, but you can use the PROJ command-line tools to reproject individual coordinate pairs from your input to your output projections so you can calculate a starting bounding box for your map. - Ed From: Bradley Mclain [mailto:bradleym06 at gmail.com] Sent: Monday, July 09, 2007 10:11 PM To: Ed McNierney Cc: MAPSERVER-USERS at lists.umn.edu Subject: Re: [UMN_MAPSERVER-USERS] [UMN_MAPSERVER-DEV] Projections Being defined by server and clients at the moment shouldn't be an issue because I am testing off the server at the moment which I have updated the proj epsg file.

Then you can refer to it as SRS=EPSG:41002 in your WMS requests and you're all set. - Ed > From: Paul Spencer > Date: Mon, 9 Jul 2007 14:55:22 -0400 > To: Ed McNierney > Cc: "MAPSERVER-USERS at LISTS.UMN.EDU" > Subject: Re: [UMN_MAPSERVER-DEV] Projections > > Thanks for the clarification Ed (and for fixing the cross-list- > posting-bug :)).

I have a working wfs, the getcapabilities works fine. I use mapserver 4.10. If I use a shapefile as datasource and then request with "GetFeature", I get a valid GML, if I change the datasource to an oracle (non-spatial, only locator) layer, I get no objects, just sth. including minx,miny,maxx,maxy I read about the wfs-server documentation and deleted all projection entrys for this layer. If I request the same layer with a wms getmap request, I see objects. If I use the same bbox in my getfeature request, I just get the above described xml. Is there a known problem as oracle uses its own internal sird (82032) ? I think the wfs is allright and only the requested bbox is wrong. Did anyone have the same problem before?

I think your problem is that you have no defined the MAXSCALE of the medium cities. This parameter tell mapserver at wich scale will stop drawing the elements of a layer (MINSCALE is how far in (MAXSCALE how far out) will be drawed the elements). So, i think if you add a MAXSCALE to the medium cities CLASS your problem will be solved: LABELITEM 'City' CLASSITEM 'City_Population' CLASS MAXSCALE 80000 NAME '0 < City_Population < 100000' EXPRESSION ( ([City_Population] >= 0) AND ([City_Population] <= 100000) ) STYLE SYMBOL 'CIRCLE' SIZE 3 OUTLINECOLOR 0 0 0 COLOR 255 170 0 END LABEL TYPE TRUETYPE FONT Arial SIZE 8 COLOR 255 255 250 #OUTLINECOLOR 255 255 255 ANTIALIAS TRUE MINFEATURESIZE 500 ANGLE 0 FORCE false END END CLASS NAME '100001 < City_Population < 500000' EXPRESSION ( ([City_Population] >= 100001) AND ([City_Population] <= 500000) ) STYLE SYMBOL 'CIRCLE' SIZE 4 OUTLINECOLOR 0 0 0 COLOR 255 170 0 END LABEL TYPE TRUETYPE FONT Arial SIZE 10 COLOR 255 255 250 #OUTLINECOLOR 255 255 255 ANTIALIAS TRUE MINFEATURESIZE 500 ANGLE 0 FORCE false END END The MAXSCALE value will depend on your map. I hope it works. Rodrigo.

Reason for this: I have a 20 pixels high very long copyright notice on the bottom of the map, which is hiding the scalebar partly now... and I really want it to have in he lower left corner... In: http://umn.mapserver.ch/index_en.php I found something like: "(Please note that embedding scale bars require that you define a markerset. In essence the scale bar becomes a custom marker that is handled just like any other annotation.)". but I don't know howto define a markerset of what it is (other than in relation with an reference map) I find the possibilities of annotationlayers amazing by the way: - using text, or transparent images or custom truetype font's you can put everything everywhere fixed on your map (after reading: http://mapserver.gis.umn.edu/development/rfc/ms-rfc-14). Is it an idea to put something in documentation about this? Specially for printing you often have to put copyright notices, custom north arrows or compasses etc in you final image.

What I did was translate your example to Perl mapscript. Some PHP methods are not available or a bit different in the SWIG versions. That looks like this: my $oShp = new mapscript::shapeObj($mapscript::MS_SHAPE_POINT); my $oLine = new mapscript::lineObj; my $oPt = new mapscript::pointObj; $oPt->setXY(-11, 22); # DD $oLine->add($oPt); $oShp->add($oLine); $oShp->{text} = 'Hello World'; my $numlayers = $map->{numlayers}; my $oLayer; for (my $h=0; $h<$numlayers; $h++) { $oLayer = $map->getLayer($h); $oLayer->{status} = $mapscript::MS_OFF; } $oLayer = $map->getLayerByName('popplace'); $oLayer->{status} = $mapscript::MS_ON; $oLayer->addFeature($oShp); # here the loop below is going to be inserted my $SVGimg = $map->draw(); my $svg_file = '/path/to/willi.svg'; $SVGimg->save($svg_file); The result is exactly like yours: including the label. Ok. But now I add the following: for (my $foo=0; $foo < 3; $foo++) { $oShp = new mapscript::shapeObj($mapscript::MS_SHAPE_POINT); $oLine = new mapscript::lineObj; $oPt = new mapscript::pointObj; $oPt->setXY($foo,$foo); $oLine->add($oPt); $oShp->add($oLine); $oShp->{text} = 'Hello World ' . "$foo"; $oLayer->addFeature($oShp); $oShp=$oLine=$oPt=undef; # don't know if this is needed } this is the result: What you see is that the labels from the loop are missing while the label from the first addFeature is there. Weird. Going through the MAP-file reference I find the 'FORCE' property for labels. Setting 'FORCE' to 'true' did the trick. All labels, including those from the loop, do now appear in the SVG. I do not know if this is exactly what I want, but at least I got my labels.

PHP/MapScript doesn't provide the TEXT portion of an annotation feature. It's because it's easier to add directly a point on the top of the map. Instead of adding a FEATURE object to the layer, simply create a point object and draw it on the map image. (Following code not tested) // Outside the loop create a pointObj $oPoint = ms_newPointObj(); $oPoint->setXY(1,1); [...snipp...] // Inside the foreach, draw your map without the copyright layer $thislayer->set("status",MS_OFF); $image[$i] = $amap->map->draw(); // Then draw the point on the top of it // Don't forget to remove the FEATURE object in the mapfile // Also you should give a name to your class in the copyright layer // For now, I'll use "CLASSNAME" $thislayer->set("status",MS_ON); $oPoint->draw($amap->map, $thislayer, $image[$i], "CLASSNAME", $filter); $image_url[$i] = $image[$i]->saveWebImage(MS_GIF,1,1,0); [...snip...] The code is not tested, but it should give you a good idea.

Thomas, You are configured to use the OGR ODBC driver, which should be available in any GDAL/OGR windows build. So there is nothing special required. The MySQL case is accessing MySQL directly rather than through ODBC. If shp2img is working, I'd suggest you carefully review permissions for use of the ODBC DSN for whatever user your web server is running as. > STYLEITEM "AUTO" BTW, I don't believe that STYLEITEM "AUTO" is going to do anything for ODBC/VRT datasources. It mostly is useful for mapinfo, and dgn file formats.

END END CLASS LABEL ... END TEXT 'Image Date Goes Here' END END Then in the script you'd use the classObj setText() method to alter the timestamp. Essentially the TEXT property allows you to set a text constant that is applied to all features. In this case it's only one. I think you'll find it's a bit more straight forward. Steve >>> "Burgholzer,Robert" 07/11/07 9:04 AM >>> Julien, Thanks for your suggestions. I am close, although the points are not being rendered. They return a "MS_SUCCESS", however, it does not show on the map.

PHP/MapScript doesn't provide the TEXT portion of an annotation feature. It's because it's easier to add directly a point on the top of the map. Instead of adding a FEATURE object to the layer, simply create a point object and draw it on the map image. (Following code not tested) // Outside the loop create a pointObj $oPoint = ms_newPointObj(); $oPoint->setXY(1,1); [...snipp...] // Inside the foreach, draw your map without the copyright layer $thislayer->set("status",MS_OFF); $image[$i] = $amap->map->draw(); // Then draw the point on the top of it // Don't forget to remove the FEATURE object in the mapfile // Also you should give a name to your class in the copyright layer // For now, I'll use "CLASSNAME" $thislayer->set("status",MS_ON); $oPoint->draw($amap->map, $thislayer, $image[$i], "CLASSNAME", $filter); $image_url[$i] = $image[$i]->saveWebImage(MS_GIF,1,1,0); [...snip...] The code is not tested, but it should give you a good idea.

My question is: who "made the mistake" and what do I have to do to show them correctly (they are shown correctly from a dwg file that is referencing them all)? Are the TFW files wrong for this resolution? Do I have to change the resolution, image size, or what?

PHP/MapScript doesn't provide the TEXT portion of an annotation feature. It's because it's easier to add directly a point on the top of the map. Instead of adding a FEATURE object to the layer, simply create a point object and draw it on the map image. (Following code not tested) // Outside the loop create a pointObj $oPoint = ms_newPointObj(); $oPoint->setXY(1,1); [...snipp...] // Inside the foreach, draw your map without the copyright layer $thislayer->set("status",MS_OFF); $image[$i] = $amap->map->draw(); // Then draw the point on the top of it // Don't forget to remove the FEATURE object in the mapfile // Also you should give a name to your class in the copyright layer // For now, I'll use "CLASSNAME" $thislayer->set("status",MS_ON); $oPoint->draw($amap->map, $thislayer, $image[$i], "CLASSNAME", $filter); $image_url[$i] = $image[$i]->saveWebImage(MS_GIF,1,1,0); [...snip...] The code is not tested, but it should give you a good idea.

What's the > best way to solve this problem? Bill, I likely shouldn't speak up since I don't really know the best way to do this. But I do not believe it can be done entirely from the server side with mapserv cgi and a map file. Either you would have to have a mapscript application on the server that decided at some point to switch projections or you would have to engineer all the logic on the client side. With WMS you can request specific projections using the SRS (or CRS?) item in the request. With the non-OGC "classic" mapserver interface there is also a way of overriding the map projection which I think has been recently discussed on this list though I don't know the exact details. But one important thing to remember is that the region requested is going to have to match the projection which means there has to be quite a bit of smarts either in the client (to change the coordinate system of the BBOX) or in a mapscript script on the server to reproject the requested box into the alternate projection. And in that case the returned window won't be exactly what was requested.

Chris, Mapserv *should* work if given enough time but for a full overview image processing through 2700 files still takes quite a while. Likewise shp2img should work. The operational solution is to create a low resolution mosaiced layer all in one file and use MINSCALE/MAXSCALE on the layers to switch between the tileindex layer and the overview layer at appropriate scales.

Are the TFW files wrong for this resolution? Do I > have to change the resolution, image size, or what? Dejan, It is unlikely that the DWG is utilizing the world files (.tfw) at all. So if the DWG view is correct it is likely that the world files are wrong. If you think the origin's in the world files are correct you could try changing the resolution in the world files to 0.8 from 0.5 and see if things are properly placed. The TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION are not used for georeferenced placement or scaling by MapServer or other applications. BTW, GDAL and MapServer will utilize internal GeoTIFF tags in preference to the world files. So if there is wrong internal geotiff info it will get used instead of potentially correct worldfiles. Keep this in mind if the world files don't seem to agree with what gdalinfo is reporting.

At full extents you still have to open 2774 images and depending on the zoom scale you might still need to take the 16th over and reprocess that. What you need to do is create external overviews using gdalwarp and then use min/max scale to control when to use the external overviews -Steve W From ed at TOPOZONE.COM Thu Jul 12 12:15:34 2007 From: ed at TOPOZONE.COM (Ed McNierney) Date: Thu, 12 Jul 2007 15:15:34 -0400 Subject: very large tile index In-Reply-To: <4696786E.90101@pobox.com> Message-ID: Chris - I will echo Frank's point from experience. Your disk subsystem, while it may be good, is the slowest part of your system and you don't mention what it is. Any disk is slowest at doing seeks from one location to another (as opposed to linear reads). Your request is, at a minimum, asking your system to open and read 2,774 individual files. Under optimal conditions this will probably require 2,774 seeks and possibly quite a few more (it wouldn't be surprising to have 5,000 - 10,000 seeks occur). A typical 7,200 RPM ATA drive will have a seek time of about 9 milliseconds, and will have an average latency of about 4.2 milliseconds. That means that a command to "open this file and read the header" will take a minimum of 13.2 milliseconds. You can only do 70 of those in one second, so if you want to do it 2,774 times you will need 40 seconds just to open all those files. Your overviews can make things considerably worse. If you wrote 2,774 TIF files to one directory, then ran gdaladdo 2,774 times on those files, you're going to append quite a bit of data to each file. If you were doing this on a blank disk, the first overview for the first file would probably need to go after the 2,774th file, etc. since the overviews are relatively big compared to your likely block size (if your files are 400MB those overviews will be 375MB). 2,774 files of 400MB each means that your first overview is over one terabyte away - that's a LONG seek. And then you'll have to go back for the next header, then back to the overview, etc. I presume you don't have a single 7200 RPM ATA drive holding your 2 terabytes of imagery , but you get the idea. Jumping around among a lot of files is a very time-consuming thing to do. Using GDAL to mosaic those file overviews together is an excellent idea. Instead of 2,774 files of 25MB each (for the 16x overview), an arrangement with 174 files of 400MB each will very likely be nearly 16 times faster. - Ed -- Ed McNierney Chief Mapmaker TopoZone.com 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 Phone: (978) 251-4242 Fax: (978) 251-1396 ed at topozone.com > From: Frank Warmerdam > Reply-To: Frank Warmerdam > Date: Thu, 12 Jul 2007 14:52:30 -0400 > To: > Subject: Re: [UMN_MAPSERVER-USERS] very large tile index > > Christopher Condit wrote: >> I've got a fairly large set of .tif files (A total of 2774 images at >> roughly 400mgs each).

Folks, Ed has hit on a dirty little secret of overviews here. Because of the way they are stored in TIFF files and the way libtiff and GDAL scan for their availability, opening a TIFF file with overviews is presumably substantially more expensive than opening a file without them. The TIFF directories will tend to be distributed through the file meaning quite a bit of seeking to get them all, and a standard GDALOpen will scan for them all. I don't want to discourage use of internal overviews. They are great from many angles. But when in use, it is still important to avoid having to touch too many files.

If you have PostGIS running, you can install the EPSG database in it (see e.g. http://docs.codehaus.org/display/GEOTOOLS/How+to+install+the+EPSG+database+in+PostgreSQL You can query this database for regions of interest for certain projections, and get their extents.

Yes, it is allowed (in fact encouraged) to use your own custom name for custom output format declarations. > Also, I get the same result with png8 and png IMAGETYPE. I don't know > why? Maybe I am missing something? I'm not sure your attempt to override the PNG output format really worked.

Dejan, MapServer uses full resolution imagery when you are zoomed in to full resolution. Perhaps the DWG viewer uses sub-pixel interpolation when you are zoomed in past full resolution. MapServer does not, by default, so things will start to pixelate at that leve.

Edward Bates mentioned that you can pass the map_PROJECTION setting on the request URL (but you'll also have to set the mapext parameter to a valid setting in the new projection's coordinate system.) If you open a MapServer map showing the USA in a Lambert projection and then append the mapext and map_PROJECTION parameters (escaping spaces and '=' signs) like so: &mapext=-122%2030%20-75%2050&map_PROJECTION=proj%3dlatlong%2cellps%3dWGS84%2cdatum%3dWGS84 to the request URL, you can change the projection on the fly. As Frank Warmerdam pointed out this will involve a bit of work to calculate the region limits in the new coordinate system. To do that on the client side, Richard Greenwood suggested a JavaScript port of some of the Proj.4 code at: http://svn.codehaus.org/mapbuilder/cscs/trunk/cscs/, and to handle it on the server side, Jan Hartmann suggested coding the solution with PHP/MapScript code and to install PostGIS and the EPSG database (http://docs.codehaus.org/display/GEOTOOLS/How+to+install+the+EPSG+database+in+PostgreSQL) The problem is bigger than I want to tackle right now, but for the meantime I can probably use something like what Bates' suggested in the form of a list of pre-selected URLs in a select control that lists a collection of fixed views for various locations and scales. - Bill Thoen From Steve.Lime at DNR.STATE.MN.US Fri Jul 13 15:47:05 2007 From: Steve.Lime at DNR.STATE.MN.US (Steve Lime) Date: Fri, 13 Jul 2007 17:47:05 -0500 Subject: Changing Map Projection Dynamically In-Reply-To: Message-ID: It is an interesting problem. MapServer templates do allow you access to the bbox for an map in both lat/lon and the projection of choice. If you are willing to live with a bit of slop you could change projections on the client and use the lat/lon bbox as an intermediate value. I would be tempted to change projections after a user submits a request (e.g. onSubmit). You have the scale value of the current map, you also have the current extent and the requested zoom value. You could with just a little bit of javascript determine a rough new scale by multiplying the old scale by the zoom factor and then change the projection (e.g. map_projection accordingly) and use the lat/lon bbox. It wouldn't be exact but would work I think. MapServer also has a little known feature called scale dependent templates. They were added for a purpose like this but I've never used them. Basically in the webObj you can set MINTEMPLATE and MAXTEMPLATE and when you hit the MINSCALE or MAXSCALE values those templates are used if defined. The can be HTML templates or URL templates. So for example, you could have an application where you zoom in to a point and then hand off to another application. The lat/lon values become the bridge. So for example, you might have separate mapfiles for each projection. They could use the same guts: MAP NAME 'scale1000to10000' ... PROJECTION ... END WEB MINSCALE 1000 MAXSCALE 10000 MINTEMPLATE 'http://mapserver.mydomain.com?map=scale0to1000.map&mapext=[mapext_latlon]&[layers]' MAXTEMPLATE 'http://mapserver.mydomain.com?map=scale10000to100000.map&mapext=[mapext_latlon]&[layers]' ... END INCLUDE 'layers.map' END MAP NAME 'scale0to1000' ... PROJECTION ... END WEB MAXSCALE 1000 MAXTEMPLATE 'http://mapserver.mydomain.com?map=scale1000to10000.map&mapext=[mapext_latlon]&[layers]' ... END INCLUDE 'layers.map' END and so on... Then you'd move between the applications as the scale changed, or at least that was the idea. This handles the in/out issue but not the east/west issue. Now, off course the min/max template could trigger a query that might, for example, set the write state plane or UTM zone and the query result fires off the right URL with the right projection, the layer list and so on. That would be all server based...

Dejan, What sort of requests are you making to mapserv? Perhaps the custom format isn't working because you are overriding the format in the mapserv request? (for instance with the FORMAT= flag in WMS requests). Other than that, I don't see any explanation for what is happening.

I have, after a week of unsuccessful tinkering, finally given in and imported the new shapes into an existing (working) table that already contained shapes within the same topic. I had hoped to keep the two data sets separate because they involve two countries and two different terminologies on the same subject. I added some columns to accomodate the second country's data. I then copied (using a simple SQL statement of the type INSERT INTO ... SELECT ...) the data from the non-working table (the one that threw the glibc error) into the abovementioned older table and - lo and behold - it worked! Why that is, is beyond me. In my understanding there must be an incompatibility in the way the newer Postgis version behaviour when one calls CreateGeometryColumn. Somehow, only geometry columns created with the older Postgis are compatible with Mapserver 4.0.1. This explains why all the older tables still worked after migrating to a new server and updating all except Mapserver. This also explains why converting the data on the old server and then pg_dumping and reimporting it into the new server doesn't help. I think I now have enough reason to justify the migration to Mapserver 4.10, costly as it may be for us. Otherwise I can't add any more tables containing geometry. What I still wonder is if I should wait for Mapserver 5 (well, more likely 5.0.1 or 5.0.2 to be on the stable side) or if I should take the 4.10 update first.

Instead, you need to install the development version of php. Something like php-devel(??) and that will give you the header files. I think this holds true for other yum installs as well.

You can point --with-php=DIR either to the original source tree that was used to compile PHP or to the install directory where the PHP header files are installed by the php-devel package or equivalent (e.g. /usr). Basically what MapServer's configure script needs is the location of the PHP header files that were used to compile your PHP installation.

But somethings are still lacking which I am not able to figure out.. 1. When I click on Reference map, the original map loses focus instead of navigating itself to that position. 2. The loading image when map is refreshed. 3. The cursor position (real world) when mouse is over the map. 4. I want to zoom-out more and the initial map should be smaller than it is now. 5. I put on copyright symbol with help of layer but (c) symbol is not clear because of font and other than that can I use graphics for this too. 6. How to resize map window for different computer screens. 7. Grids are not working. I have pasted my html code below the message.

And finally a "display:none;" in the style will make it to not be showed by default... something like: I hope you understand what I'm talking about but ask me again if you can't get it working.

Antognini Hi Assuming your are working with esri shape files (*.shp, *shx, and *.dbf), php_mapscript allows you to add new shapes and you can use php dbase functions to add new records (and datas) to the dbf file.

As of mapscript 4.10 you need to initialize the shapes to receive values. try issuing a $shp->initValues(1); before setValue. The int argument is the number of values you will set in that shape.

Using OL's mechanisms, I'd do something along these lines: Set up the OL map to do click-queries via WFS's getfeatureinfo. See http://world.freemap.in/ You'll have to set up your mapfile to act as a WFS server, which is very simple following the WFS Server howto on the Mapserver documentation site. Since you want it to click the map on a hover instead of a click, I'd probably throw together a combination of JavaScript setTimeout(), and extending the map's mouse movement handlers so they the timer is reset whenever the mouse moves, and is started when the movement ends. > Currently all I have is markers being placed on the specific locations > with no pop-up info or anything.

(Preferably textfile in the short term for > testing but eventually a database would be ideal). If you use WFS, the data comes from the same data source you're already using, saving you the trouble of duplicating it, or writing a database app to fetch a single feature and generate XML for it, etc. Hooray for OGC standards and to Mapserver for making them easy. As far as popups go, I think that only RSS layers support that in OL, and that's probably not at all what you want. Mapserver itself doesn't do anything of the sort, unless you count labels with a colored background. Then again, if you're creative, your WFS-query click-handler could probably populate a HTML div like in the example at the URL I gave, and position the div at the mouse's current location; it'd be some work, but probably nothing too arduous if you're handy with JS and HTML. I hope that helps. Aside from setting up your mapfile to be a WFS server, I suspect that most of your work will be in OL or in general JavaScript. -- Gregor Mosheh / Greg Allensworth System Administrator, HostGIS cartographic development & hosting services http://www.HostGIS.com/ "Remember that no one cares if you can back up, only if you can restore." - AMANDA From hindemit at TISCALI.IT Thu Jul 19 00:34:50 2007 From: hindemit at TISCALI.IT (Antonio) Date: Thu, 19 Jul 2007 09:34:50 +0200 Subject: newbie and cmap Message-ID: hi all, I'm an italian developer at the first post on this ml ... now the question ;-))) i'm trying to implement a mapserver to catch the gps signal from some boat and reproduce their movement on the map ...

Sander, Do you have a sense where things are going wrong? Is it the scaling or the LUT application? I will note that the lut management code assumes that 0 maps to 0 and 255 maps to 255. So I don't think your 255:0 specifications are going to work.

Jan / Bob, How would you see this working? Would it be a request made against a particular layer? Against the map as a whole? Internally in the code we have: int msLayerGetExtent(layerObj *layer, rectObj *extent) which calls the data source specific GetExtent function. But I don't think this works for raster layers. There is also msOWSGetLayerExtent() which first consults the layer metadata for extents. Perhaps this would be the logical place to look? Well, I suppose the other side of this is that for WMS and WCS the layer and coverage descriptions include extents already. Is that sufficient for your needs?

I think the problem lies in the LUT application. When all 3 bands end with 255:255 then you really say that the highest value is always white. When you apply a max scaling then the area with the maximum value is larger and more apparent. > > I will note that the lut management code assumes that 0 maps to 0 and > 255 maps to 255. ?So I don't think your 255:0 specifications are > going to work. If I don't put the 255:0 there then there's an interpolation between the last pair (157:0) and 255:255 which is undesirable. By putting the 255:0 there I prevent the code from interpolating "back up". My last pair should formally be 254:0 which then is appended with 255:255. All in all I don't think that automatic catenation of pairs is a good idea because min and max values are fixed to black and white repectively.

You are right that WMS and WCS will give back the extent via a GetCapabilities request, but that is exactly the thing that I would like to do with native MapServer. I just want to be able, before I request the actual map, to get its extents via a separate call. AFAICS the problem is not so much implementing this functionality (it's already there for WMS and friends), but to agree how to send back the results (XML, GeoJSON, etc) Jan Frank Warmerdam wrote: > Jan Hartmann wrote: >> I second that question.

Either seperately or as a composite extent. A XML output would be good for example, but not required. I could build a wrapper to do a composite from an individual list if a composited version is too much overhead. My use case: My Client application deals with layers on an individual basis with separate calls, etc.: * I would like to have a displayable layer (user controlled) in my client application that shows the extent of a particular layer. * This same capability allows me to gray out a layer that is turned on, but not visible in a current View. * This would also allow me to filter for layers that are out of bounds and not request them automatically (as I do now) and and up displaying a blank image. A definite performance enhancement I think. * An addidtional feature I would like to add to my client is a Reference image/map, that shows the layer extents. This would be used as a thumbnail in a layer metadata lookup/popup. Some WishList things (not really expected near term): * Using a bounding polygon vs a rectangle. * Feature counting (We've been over this feature with Steve L a couple of times), basically a method of counting features in a layer. o Further enhancement, would be to be able to count the features inside of a mapext. * Adding in Layer (data source) feature lists (metadata kinds o f things that could be derived by MapServer, either by examining the data or the file/db that contains it. o Date of sourced data (last update in a DB environment) o TYPE (Raster, Line, Polyline, Polygon, etc.) -------------- Some possible thoughts/solutions I had on the subject: * Set up some commandline utility that can generate the extents from a layer(shpfile) list as a new layer specifically related to Spatial metadata (actually this idea has a bunch more too it, that goes beyond this topic). This new layer could be queried for all the appropriate info, it would also allow for adding in some additional link mechanisms that would be layer based. * Use the previous setup to build this type of data layer by default as a setup feature of MapServer. Again there are some other things here that could obviously be added to an indexing system like this. Possible use some sort of MapServer Configuration step periodically to keep the extents layer up to date. * Don't know if/when I would be able to get to it, but I would build this in PERL/MapScript myself if it's not plausible to include in MapServer. bobb Frank Warmerdam wrote: > Jan Hartmann wrote: >> I second that question.

For instance, the first code line: empty_map = new mapscript.mapObj doesn't work. I get an error about the mapscript class being missing. In other places, it doesn't like the dot notation (and I thought that PHP uses an arrow -> instead anyway). I suppose the problem here is that this isn't really *PHP* mapscript, but if it's not, how do I translate this "code" into something useful? - Bill Thoen From hulst at ARGOSS.NL Fri Jul 20 07:23:14 2007 From: hulst at ARGOSS.NL (A.Th.C.

I'm not sure that this is advisable. I'd suggest you file a specific bug against MapServer indicating what you consider is the issue, and your proposed solution.

The name you use for the encoding in the gml_encoding metadata may not be exactly the same as what you find in the .tab file's Charset line, you may have to find the encodig name that is suitable for use in a element.

Even the MGOS mentions the ability to load DWG files but even through Web Studio I can only see SDF and SHP as valid Data Types. I would prefer to do this without Mapguide Studio as there might be a batch of files and it would be nice if the server could just pick them up in the folder.

I?ve created a layer that shows bridges etc. of roads. I?m using a font that has a ?bridge-symbol?. The direction of the nearest road in angles is stored in a attribute of the bridges-data. It works fine with pixmap symbols. When using truetype font symbols and the angle is 0 it also works fine. But when the angle is getting bigger the symbol deviates more from the real point. The symbol is rotated fine. I think this has to do with the point of rotation of the truetype symbol. In pixmap?s the point of rotation is the center that?s why it works fine. I?m using a truetype font symbol because I want the symbols fully transparent. When the pixmap symbol is rotated it isn?t transparent anymore. I thought this was a good solution?.. Can anyone help? My ?code? in the mapfile: LAYER ?. TYPE POINT TRANSPARENCY alpha CLASS NAME "bridge" STYLE #Used in older versions: ANGLEITEM ?nearest_road_direction? ANGLE [nearest_road_direction] COLOR 0 255 0 SYMBOL "bridge" SIZE 10 END STYLE COLOR 255 0 0 SYMBOL "point1" SIZE 10 END END END SYMBOL NAME "bridge" TYPE TRUETYPE FONT symbolfont FILLED TRUE CHARACTER "D" ANTIALIAS TRUE END SYMBOL NAME "point1" TYPE ellipse points 1 1 end FILLED true END So when the angle is bigger then 0 the symbol ?point1? and the center of the symbol ?bridge? is not shown on the same point.

I've spent some time searching the MapServer forums and Google, and I still have not found an answer... I'm working with the C# mapscript library. It works as follows: A user sets up a filter for what they want returned in a search. Then they determine the region over which to search (currently I have it only searching over a point and a tolerance level defined). I pass the field to be filtered to the layer's filteritem property, and call the layer's setFilter method, and pass in the what it is the user wants to see. As an example, layerObj ms_layer = map.getLayerByName("county"); ms_layer.filteritem = "countyid" ms_layer.setFilter("[countyid] = 67"); I then perform a queryByPoint query on the layer, which returns a MS_FAILURE value. If I remove the call to ms_layer.filterItem, the query succeeds, but the results are not filtered. I've tried a variety of string combinations in the setFilter(...) method, including the following: [countyid] = 67 "[countyid] = 67" [countyid] = "67" ( [countyid] = 67 ) [countyid] == 67 "[countyid] == 67" ... and so on and so forth. Just as a reference point, here's my call to the query... Ms_layer.queryByPoint(map, queryPoint, mapscript.MS_MULTIPLE, tolerance); I'll welcome any insights or theories on this matter.

I am using the latest map > server and dbox. Asif, I imagine you are running into the classic "no unique identifier" problem. The two pass query mechanism used for identify/getfeatureinfo only works properly if features have a unique feature id. But some OGR drivers just set a feature id based on the order of returned records in a resultset. When a filter is applied the subset are still just numbered 1,2,3 even though they have different feature ids when no filter is applied. The fix is to ensure OGR can assign a persistent feature id to records. The OGR ODBC driver attempts to select a singular integer primary key as the feature id if one is noted. But some ODBC drivers don't provide this info properly. Also, if you are using an SQL result for your query instead of "plain table access" then this is defeated. You can force the OGR ODBC driver to use a particular column by setting the ODBC_OGR_FID configuration variable but this is a blunt tool for the job. The other approach is to add an columnname element in your OVF definition of the virtual layer. This tells the OVF driver to use a particular column for the fid. I'd suggest you do this. Note that MapServer queries through OVF/ODBC are somewhat fragile and the performance can suck since it ends up doing fetches by feature id which can be pretty slow. In MapServer 5.2 we hope to alter the query mechanism such that it will be one pass, resolving the fid requirement and performance issues.

Message-ID: Hi all, I wanted to figure out if it is possible to use an attribute to build a "dynamic" symbol for a point layer. Let's say I create a triangle as a symbol definition and wanted to show a number as the attribute of that point inside the triangle on the map - just like a label but inside the symbol. The only way I found to do that would be to create an individual symbol definition for each number that exists in the attributes (each would be a small image for example). Is there any way that I could create a dynamic symbol (similar to a combination of the label and symbol)?

In-Reply-To: <014501c7ce35$07c4e040$6501a8c0@snuggie> Message-ID: Hey, Karsten. Using pure Mapserver, you may be able to fudge something using a label and setting the label's position. If the label is centered, and the icon is big enough, and you tweak the label's font and size, it may look good enough for your needs. Other than that, I think you're out of luck. Mapserver uses predefined symbols and predefined classes. Using Mapscript, you get a lot of wiggle room as far as, for example, dynamically defining coordinates to define a new symbol on the fly. -- Gregor Mosheh / Greg Allensworth System Administrator, HostGIS cartographic development & hosting services http://www.HostGIS.com/ "Remember that no one cares if you can back up, only if you can restore." - AMANDA From woodbri at SWOODBRIDGE.COM Tue Jul 24 14:38:09 2007 From: woodbri at SWOODBRIDGE.COM (Stephen Woodbridge) Date: Tue, 24 Jul 2007 17:38:09 -0400 Subject: AntiAlias dashed line Problem Message-ID: Hi all, I have a strange problem that I can't figure out.

Milo, I'm not too sure whether MapServer tries to do character encoding changes. I gather it may in some circumstances. But OGR does not currently have any concept of the character set of a datasource. So OGR is certainly not able to indicate to mapserver what the input encoding is which I would guess means that no correct transliteration can be done.

Thanks. This was never implemented and it is non-trivial (and expensive) to compute the offset curve that would be need to place the character on. The offset would have to deal with adding and removing line segments in the offset. Think about this line: ---- \ / ------- ---------- The notch would need to be removed if you offset on the lowest side of the line otherwise you would create self intersection that would be bad for labeling.

ESS will initiate a change from a cost recovery environment to an environment providing no fee access to its current DTD products. On April 1st, 2007, NRCan will start to make its existing DTD products available through the Geogratis Web portal. By combining the functionality from the current On-line Purchasing and Subscribers Web sites, the user will be provided with no fee access to DTD products. Under the new distribution policy, commercial licenses will no longer be required, as all users will obtain rights for unlimited use and royalty-free distribution of the data through a single unrestricted use license agreement. For subscribers, this means that beginning on April 1st, 2007, you will no longer have to pay for access rights or subscriptions for DTD products. Please note that your subscriber connection profile will remain active until April 1st, 2007, enabling you to download data as defined under the current agreement. For distributors, this means that beginning on April 1st, 2007, you will no longer have to pay royalty fees for the commercial use of DTD products. While this email serves as informal notification of our intent, official correspondence, accompanied by Letters of Mutual Consent which we request that you sign and return to NRCan, will be sent out in the next couple of days to formalize the termination of the existing contractual arrangements. We are grateful for your collaboration over the years and hope you will continue to support us in our efforts to make it easier to access, use and distribute Canada's digital topographic data. Please do not hesitate to contact me if you have any questions. ***** En r?ponse aux demandes des usagers pour avoir un acc?s sans frais aux donn?es g?ographiques cadres et compte tenu du changement technologique qui ne cesse de prendre de l'ampleur dans le march?, Ressources naturelles Canada (RNCan) est ravi d'annoncer qu'? compter du 1er avril 2007, le Secteur des sciences de la Terre (SST) changera la mani?re d'acc?der ? ses donn?es topographiques num?riques (DTN).

The most basic way is to call mode=map like you're used to seeing, and just grab the resulting image. If you're using mapserv.js then just save the value of map.url and there's your image. If you mean geospatially referenced imagery, e.g. a GeoTIFF, then you want WCS (web coverage service). It's like WMS, except that the output is a geo-image instead of a plain image. Check the Mapserver documentation, the howtos, and read about setting up a WCS server and then testing it. You should find it easy to adapt the test URLs from the tutorial over to JavaScript or HTML to do what you want. -- Gregor Mosheh / Greg Allensworth System Administrator, HostGIS cartographic development & hosting services http://www.HostGIS.com/ "Remember that no one cares if you can back up, only if you can restore." - AMANDA From rwburgholzer at DEQ.VIRGINIA.GOV Wed Jul 25 11:58:35 2007 From: rwburgholzer at DEQ.VIRGINIA.GOV (Burgholzer,Robert) Date: Wed, 25 Jul 2007 14:58:35 -0400 Subject: Download Raster(imagery) Message-ID: Essentially, this is what the user does every time you generate a map via mapserver, if I understand your desire correctly.

I?ve created a layer that shows bridges etc. of roads. I?m using a font that has a ?bridge-symbol?. The direction of the nearest road in angles is stored in a attribute of the bridges-data. It works fine with pixmap symbols. When using truetype font symbols and the angle is 0 it also works fine. But when the angle is getting bigger the symbol deviates more from the real point. The symbol is rotated fine. I think this has to do with the point of rotation of the truetype symbol. In pixmap?s the point of rotation is the center that?s why it works fine. I?m using a truetype font symbol because I want the symbols fully transparent. When the pixmap symbol is rotated it isn?t transparent anymore. I thought this was a good solution?.. Can anyone help? My ?code? in the mapfile: LAYER ?. TYPE POINT TRANSPARENCY alpha CLASS NAME "bridge" STYLE #Used in older versions: ANGLEITEM ?nearest_road_direction?

When angle equals 0 it is.The 'only' thing i want to do is rotate fully transparent symbols at a point...

Hey, Karsten. Using pure Mapserver, you may be able to fudge something using a label and setting the label's position. If the label is centered, and the icon is big enough, and you tweak the label's font and size, it may look good enough for your needs. Other than that, I think you're out of luck. Mapserver uses predefined symbols and predefined classes. Using Mapscript, you get a lot of wiggle room as far as, for example, dynamically defining coordinates to define a new symbol on the fly. -- Gregor Mosheh / Greg Allensworth System Administrator, HostGIS cartographic development & hosting services http://www.HostGIS.com/ "Remember that no one cares if you can back up, only if you can restore." - AMANDA From dmorissette at MAPGEARS.COM Thu Jul 26 07:03:56 2007 From: dmorissette at MAPGEARS.COM (Daniel Morissette) Date: Thu, 26 Jul 2007 10:03:56 -0400 Subject: MapServer 5.0.0 release plan ... and release of beta1 In-Reply-To: <259e26270707251442q7421e815j5481c0c2c5481a5d@mail.gmail.com> Message-ID: Ben Tuttle wrote: > Does MS RFC 24 address bug #1975?

For example, I've got a US Interstates layer that has been thinned so that it is appropriate for scales smaller than 1:10,000,000, and I've got another one that I'd use at larger scales (but from 1:10,000,000 to 1:5,000,000 I want to use one style and for scales between 1:5,000,000 and 1:1,000,000 I want to use another style on this layer). Then I've got some MapInfo seamless road layers that have the highest detail that I'd use at the largest scales, but for these too, I have three different styles depending on the display scale. Can a MapServer WMS server support this sort of thing or should I load each layer as needed and style it in the WMS client MAP file? I know how to do the latter, but it would be much more convenient to make one call to a WMS and get all the appropriate layers rendered with the desired styles in one LAYER call in my client MAP files. I've read the how-tos for WMS client and server, and glanced at the article about SLD's (but haven't understood that very well yet) but so far I haven't seen this issue addressed specifically.

How I'd do it, and I'd love to hear other methods/opinions... Set up multiple layers, and give them all the same GROUP. In case you're not familiar with it, a group defines a "virtual multi-layer layer" and the WMS client would get all of those layers together when it requests the one layer. Then, define your multiple layers to each use appropriate MINSCALE and MAXSCALE. e.g LAYER GROUP "roads" NAME "allstreets" MAXSCALE 100000 END LAYER GROUP "roads" NAME "countyroads" MINSCALE 100001 MAXSCALE 1999999 END LAYER GROUP "roads" NAME "highways" MINSCALE 2000000 END Ta-da, now the "roads layer" will automagically change with the scale.

We do something similar here internally with our aerial orthos, except we have one mapfile per logical layer and just set status=default in all of the layers in the mapfile so they will always be rendered, no matter which one the client chooses. (The min/max scales are setup so only one layer from the mapfile will be active at any given scale.) >>> Bill Thoen 07/26/07 9:41 AM >>> I'm starting to build a MapServer WMS server that will provide national street layers to my MapServer client but I have some questions about how to approach the problem of serving alternate layers designed for different scales and same layers with different styles depending on the scale. For example, I've got a US Interstates layer that has been thinned so that it is appropriate for scales smaller than 1:10,000,000, and I've got another one that I'd use at larger scales (but from 1:10,000,000 to 1:5,000,000 I want to use one style and for scales between 1:5,000,000 and 1:1,000,000 I want to use another style on this layer). Then I've got some MapInfo seamless road layers that have the highest detail that I'd use at the largest scales, but for these too, I have three different styles depending on the display scale. Can a MapServer WMS server support this sort of thing or should I load each layer as needed and style it in the WMS client MAP file? I know how to do the latter, but it would be much more convenient to make one call to a WMS and get all the appropriate layers rendered with the desired styles in one LAYER call in my client MAP files. I've read the how-tos for WMS client and server, and glanced at the article about SLD's (but haven't understood that very well yet) but so far I haven't seen this issue addressed specifically. Does anyone have any suggestions about how to do this, or can you point me to any documentation I should read?

Josh, This seems like permissions problems. I don't quite "get" the permissions model under windows, but I'd suggest: 1) make sure your DSN is a system dsn, not a user dsn. 2) Investigate what you need to do to let your web user have permission to use the DSN. BTW, 7 seconds to render the points layer with shp2img is pretty terrible. Are you sure you want this to work? There are some mechanisms to have the spatial query passed down to SQL Server to be evaluated against the table. This might improve performance substantially. Contact me off list if you can't find enough info in the OVF howto on mapserver.gis.umn.edu or in the OGR VRT driver docs.

I find that antialiasing and transparency just don't work well together; the antialiasing gets turned transparent, which makes it look awful. I'd love to hear advice on this topic, as I have similar issues with fonts and symbols looking crummy under transparency. If it's not transparency, how about your image format? Are you using JPEG? JPEG is nice stuff, but you've probably seen JPEGs that get all crummy if someone tried to compress too hard. Try setting the OUTPUTFORMAT options to turn up the JPEG quality to 100. Anything beyond that, we'd probably need to know a thing or two about your image format, maybe see an example of it, ... -- Gregor Mosheh / Greg Allensworth System Administrator, HostGIS cartographic development & hosting services http://www.HostGIS.com/ "Remember that no one cares if you can back up, only if you can restore." - AMANDA From doug at GIS-SOLVED.COM Thu Jul 26 13:53:20 2007 From: doug at GIS-SOLVED.COM (SUBSCRIBE MAPSERVER-USERS DougC) Date: Thu, 26 Jul 2007 15:53:20 -0500 Subject: GeoRaster Oracle support Message-ID: Hi all I am new to the world of Mapserver and am trying to see if MapServer supports the sdo georaster datatype in Oracle 10gR2 database.

That's because the NODATA value is not recognized ?as such and the resampling algorithms are using -32767 as a normal value, ?leading to 'fun' values like -16145 when computing averages. My proposal ?is to force the noData value as offsite.red when the source is a one band ?image. ?The following addition in msResampleGDALToMap fixes this : ?{{{ ? ? ?if (srcImage->format->bands == 1) ? ? ?{ ? ? ? ?void* hBand1 = GDALGetRasterBand( hDS, 1 ); ? ? ? ?noData = msGetGDALNoDataValue( layer, hBand1, &bGotNoData ); ? ? ? ?if (bGotNoData) ? ? ? ?{ ? ? ? ? ?layer->offsite.red = noData; ? ? ? ?} ? ? ?} ?}}} ?But, this fix is not really sufficient to address the correct handling of ?DTED files. In aeraunatical applications using DTED files, the meaning of ?the NODATA value is really 'unknown', 'there's maybe a big mountain here ?but no data collected'. So, you often prefer the propagation of the ?uncertainty of the source to the result, rather than a clever ?interpolation that may be dangerous for the final user. So, if for some ?processing of an application, you need to resample a DTED Level 2 file to ?a lower resolution, like near the resolution of a DTED1 file, you want ?-32767 to be the result of the resampling as soon as one of source grid ?elements is -32767. ?With the small patch above, those source grid elements are just ignored ?for the computation.[[BR]] ?So, I've introduced a new PROCESSING directive ('STRICT_NODATA=YES') that ?enforces the propagation of the noData value. Of course, when using ?STRICT_NODATA=yes, you should also set 'LOAD_FULL_RES_IMAGE=YES' to be ?sure that all the source grid elements will be read. And of course, the ?default resampling method, NEAREST, doesn't make much sense... Debug ?warnings are emitted when those 2 conditions are not met. ?PS : I've a longer patch that adds another INTERPOLATION method, 'MAXIMUM' ?useful for aeronautical applications too (safety altitude computations for ?example). As its name suggests, it takes the maximum value of the source ?grid elements (except a noData value ;-)). As it depends of this current ?patch, I've thought that I should delay its posting. ?PS2 : It doesn't include the small patch I've previously sent for the ?reprojection/tileindex issue (http://trac.osgeo.org/mapserver/ticket/2180) From szekerest at GMAIL.COM Thu Jul 26 16:24:31 2007 From: szekerest at GMAIL.COM (Tamas Szekeres) Date: Fri, 27 Jul 2007 01:24:31 +0200 Subject: C# MapScript & GAC In-Reply-To: <2534c4120707261233k51f38704id71ce1f13207b5da@mail.gmail.com> Message-ID: The SVN trunk have been modified so that the mapscript_csharp.dll is signed with a strong name.

My first attempt was to set the WIDTH property of the STYLE element to 0 in my MapFile but I got an error from MapServer, it seems to be an invalid value. As I might need to display the same data through GeoServer, I decided to move all style information to a SLD. I wrote the following SLD : water Water bodies #99b3cc #0000FF 0.0 My map is rendered without any error but there is still an outline. I tried to set opacity to 0.0 but it's not supported by MapServer. I can set the same color for stroke and fill but having a 1px outline means that a very thin river is rendered with, at least, a 2 pixels width and this is not really nice when viewing the map at higher scales... If I remove the Stroke element Mapserver seems to set automatically a 1px outline using the fill color.

Josh, This seems like permissions problems. I don't quite "get" the permissions model under windows, but I'd suggest: 1) make sure your DSN is a system dsn, not a user dsn. 2) Investigate what you need to do to let your web user have permission to use the DSN. BTW, 7 seconds to render the points layer with shp2img is pretty terrible. Are you sure you want this to work? There are some mechanisms to have the spatial query passed down to SQL Server to be evaluated against the table. This might improve performance substantially. Contact me off list if you can't find enough info in the OVF howto on mapserver.gis.umn.edu or in the OGR VRT driver docs.

To summarize the problem, I've set up a MapServer WMS Server that's got road data in native MapInfo format with a coordinate system based on Lat/Long (EPSG:4269). When I display it in a MapServer client map using the same projection EPSG:4269, the line work looks nice and clean.

The "wms_srs" metadata in a client WMS connection layer definition is used to list all the projections (SRS) supported by the remote server. It's a space-separated list, e.g. LAYER ... METADATA "wms_srs" "EPSGL4326 EPSG:4269 EPSG:2163" ... END ... END If the requested SRS is not found in this list then MapServer concludes that the remote server doesn't support that projection and then it uses the layer's default SRS for its GetMap call to the remote server and then reprojects the resulting image on the fly. This is probably what's happening here and explains the shabby looking lines.

What do y'all think is the best way to do it? Sam, I was going to suggested using the RFC 6 colorrange mechanism, but on reflection, I'm pretty sure I never implemented it for raster data. The "normal" approach is just to use quite a few classes - one per color. It's hard to have enough classes to give really continuous color, but you can do a bunch of graduations and assign each range a nice name (or numeric value range in text) to appear in the legend.
