Subject: [mapserver-users] QGIS / Mapserver WFS filter (bbox/envelope)
	interoperability issue
Message-ID: <CAB2Z92CWV62uroii3DpdxTxGkQ+XbdWrKcT=TACHFbUVhkrJpA@mail.gmail.com>

Hi,

My current employer runs QGIS on Windows and we would like to access a WFS
server provided by an UMN mapserver provided by another authority in
Switzerland (they run UMN Mapserver 7.0x for now). We'd like to use an
envelope or box to get filtered features from that WFS.

QGIS has a method called ST_MakeEnvelop() for creating a box geometry. When
the request is sent to the UMN mapserver, the filter result looks like this:

<fes:Filter xmlns:fes="http://www.opengis.net/fes/2.0" xmlns:gml="
http://www.opengis.net/gml/3.2">
    <fes:And>
        <fes:PropertyIsEqualTo>
            <fes:ValueReference>kanton</fes:ValueReference>
            <fes:Literal>SO</fes:Literal>
        </fes:PropertyIsEqualTo>
        <fes:Intersects>
            <fes:ValueReference>wkb_geometry</fes:ValueReference>
            <gml:Envelope srsName="urn:ogc:def:crs:EPSG::2056">
                <gml:lowerCorner>2612000 1245500</gml:lowerCorner>
                <gml:upperCorner>2613500 1246500</gml:upperCorner>
            </gml:Envelope>
        </fes:Intersects>
    </fes:And>
</fes:Filter>

The reply from UMN 7.0.x is that this filter is unsupported. UMN would,
however, support something like:

<Filter>  <Intersects>    <PropertyName>msGeometry</PropertyName>
<Box srsName='EPSG:2056'>      <coordinates>2612000,1245500
2613500,1246500</coordinates>    </Box>  </Intersects></Filter>


So there seems to be an interoperability issue here between QGIS and UMN:
QGIS has no method to send the "Box" syntax that UMN would accept and UMN
doesn't seem to accept the "Envelope"-style syntax that QGIS would generate
when the user is using the ST_MakeEnvelope() function:

[image: image.png]

So my question: is a newer version of UMN (7.2, 7.4, 7.6) perhaps the
"Envelope" style syntax in the WFS filter that QGIS Desktop is sending or
should we better try to add a new "bbox" method to the WFS Client of QGIS
Desktop? I quickly browsed through the UMN Mapserver changelogs but didn't
see any obvious improvement around "Envelope" support in filters.

Thanks for your thoughts,
Andreas

Hi Andreas,
	
this is quite unfortunate MapServer doesn't support gml:Envelope as a geometry in the 
"Intersects" request, whereas we support it inside a <BBOX> filter.
The optimistic in me says that shouldn't be too hard to fix.

The supported geometries inside "intersects" are at:
https://github.com/mapserver/mapserver/blob/master/mapogcfilter.cpp#L1015

It doesn't look however that gml:Box would be legal in GML 3.2 (so with WFS 1.1 or 2.0) as it 
is a legacy from GML 2 or perhaps even older. MapServer doesn't care much about GML 
versions and compliance to schema on input side, but other servers might reject a 
fes:Intersects with a gml:Box

Was indeed simple to fix:
https://github.com/mapserver/mapserver/pull/6091

On QGIS client side, you may try with WFS 1.0. I don't think QGIS will emit a gml:Envelope 
then

Hi Even,

Wow - thanks a lot!

Also, your other assumption was right - when switching the WFS version to
1.0 in QGIS, the ST_MakeEnvelope() from QGIS Desktop as a WFS client seems
to be translated to <gml:Box/> instead of envelope:

Here is the filter request from QGIS, when choosing WFS 1.0:

<ogc:Filter xmlns:ogc="http://www.opengis.net/ogc" xmlns:gml="
http://www.opengis.net/gml">
<ogc:And>
<ogc:BBOX>
<ogc:PropertyName>wkb_geometry</ogc:PropertyName>
<gml:Box srsName="EPSG:2056">
<gml:coordinates cs="," ts=" ">2437300,1064250
2872700,1305750</gml:coordinates>
</gml:Box>
</ogc:BBOX>
<ogc:And xmlns:ogc="http://www.opengis.net/ogc">
<ogc:PropertyIsEqualTo xmlns:ogc="http://www.opengis.net/ogc">
<ogc:PropertyName xmlns:ogc="http://www.opengis.net/ogc
">kanton</ogc:PropertyName>
<ogc:Literal xmlns:ogc="http://www.opengis.net/ogc">SO</ogc:Literal>
</ogc:PropertyIsEqualTo>
<ogc:Intersects xmlns:ogc="http://www.opengis.net/ogc">
<ogc:PropertyName xmlns:ogc="http://www.opengis.net/ogc
">wkb_geometry</ogc:PropertyName>
<gml:Box xmlns:gml="http://www.opengis.net/gml" srsName="EPSG:2056">
<gml:coordinates xmlns:gml="http://www.opengis.net/gml" cs="," ts="
">2612000,1245500 2613500,1246500</gml:coordinates>
</gml:Box>
</ogc:Intersects>
</ogc:And>
</ogc:And>
</ogc:Filter>

Thanks a lot to both Even and James for your help!

Subject: [mapserver-users] WMS server error. Invalid layer(s) given in the
 LAYERS parameter. A layer might be disabled for this request
Message-ID: <CAGS7f4XK02jun7y3B3Li6=RKb129Pob=PjUv9rHBT6D5+HyysA@mail.gmail.com>

Hi All,

 I have a Mapserver 7.6.0 wms server set up and it's generating images
correctly in most circumstances.

  However, I have a wms mapfile consisting of 252 layer classes defining
all of the country polygons in a Natural Earth world shapefile.

   In some instances, I need to send up to 90 FIPS codes to my mapfile in
order to highlight the requested polygons on a map.  However, given the
large number of lFIPS code and layer classes being parsed by the mapfile,
these mapfile requests are timing out or taking a long time to return an
image.

  In order to increase response time, I sub-divided the main mapfile into
five sub-set mapfiles containing approximately 50 layer classes,
corresponding to a matching number of FIPS codes each.  However, when I
send all 90 FIPS codes for processing to any of the subset mapfiles, I get
the following error

"msWMSLoadGetMapParams():WMS server error. Invalid layer(s) given in the
LAYERS parameter. A layer might be disabled for this request. Check
wms/ows_enable_request settings."

  I believe that this is due to my requesting layer classes not found in
the sub-set mapfile.

  I've reviewed the Map Server 7.6.0 documentation and can't find a
parameter or switch to toggle this type of checking off.  Is there any way
to turn off layer class checking in order to resolve this issue?

  Lastly, when I test the same MapServer URL string using my sub-set
mapfile (sending all 90 FIPS codes using the LAYER parameter) using a web
browser command line, it returns an image consisting of all f the expected
polygons (and no WMS error).

  Thank you for any assistance you can provide to reconcile this issue.

Cheers,

Karl

Very interesting comparison.
I wonder how this statistics would look like if MapServer had a built-in
web administration interface like the other competing applications.

Hi Folks,

(Disclosure: I'm the person behind that blog post.)

 > I wonder how?this statistics would look like if MapServer had a 
built-in web administration interface like the other competing applications.

The fact MS is so high without it shows it may not be that important, at 
least not to the core audience.

I think the biggest differentiator in the stats between the top three 
may be the fact that MapServers don't have any sort of catalog of 
services or other way to find other services on the box. By which I 
mean, ArcGIS Server allows you to crawl it and get all of the public 
services and datasets. GeoServer if there are namespaces (their way of 
grouping things into services) you can go up a level and see what the 
root is serving, thus potentially finding more datasets and another 
service that way (but only one). But MapServer doesn't have a mechanism 
like that apparently (I asked on this list a couple years ago), which 
means that it's hard to know if I've found everything on a specific box. 
That's the biggest catch with the MapServer stat at least.

Cheers,

Jonathan

All,

Had a good (virtual) meeting in May. Good signup numbers as well, even some out of towners joining in. Michael Battaglia gave a nice presentation on the Great Lakes and Coastal Wetlands.  A link to a recording of the presentation can be found on our Local Chapter page below.

This month we have Jeff McKenna and Steve Lime who will do a ?State of MapServer? presentation. We?re going Virtual again for this month.





Here is the connection info:

Subject: [mapserver-users] SSL curl error when hitting HTTP WMS
Message-ID: <CH2PR19MB379989A4A3993D416914682FEF820@CH2PR19MB3799.namprd19.prod.outlook.com>

I'm attempting to hit a WMS using HTTP, not HTTPS, but I run into the following SSL error

HTTP: request failed with curl error code 60 (SSL certificate problem: unable to get local issuer certificate)

I can get around this error by downloading a CA bundle file and setting the CURL_CA_BUNDLE environment variable to point to it, but why is a CA bundle file necessary when not even using SSL (hitting a WMS using HTTP, not HTTPS)?  Does anyone know a workaround that wouldn't require deploying a CA bundle file to my servers and setting an environment variable to point to it?

I'm currently using the stable release of MSVC 2017 x64 package downloaded from GISInternals - http://www.gisinternals.com/release.php

A sample mapfile looks like this

MAP

Hi,

The service indeed seems to redirect into https address.

GDAL has an "unsafeSSL" option but I believe that Mapserver does not http://osgeo-org.1560.x6.nabble.com/https-url-with-MapServer-as-WMS-client-td5332403.html.

Perhaps you could bypass the certificate check by setting a general curl insecure option as in https://www.cyberciti.biz/faq/how-to-curl-ignore-ssl-certificate-warnings-command-option/. However, it feels rather risky to do it at that level.

Should a bug/enhancement request be opened against this?
Maybe there should be an option like:

PROCESSING "UNSAFESSL=YES"

So mapserver can handle this directly from the mapfile?

Thanks for the explanation about the redirect; that makes perfect sense now.

It would be great if there were an "unsafeSSL" option like Jukka mentioned GDAL has; figured I should at least ask whether something like that existed.  At least I now have confidence that I'm not missing some more convenient solution and that configuring the CA bundle correctly is the best course of action at the moment.

That's some great info you put together in the HTTPS document Jeff!

Hi Scott: Nope, the various scale denominator properties are not mutable
via URL parameters. It's a relatively simple change to make it happen (just
modify maplexer.l (look for the keyword of choice) and rebuild) but I'm not
sure it's a great idea since you could be opening up some performance
headaches for both your mapping box and backend data sources. I mean, a
user could essentially affect at what level high density data could be
drawn at, so imagine asking for high density roads at a global scale from a
remote PostgreSQL/PostGIS source.

Thanks for the response.

My mapserv binary is in a wrapper so I have control over dubious 
features I may (intentionally) introduce.

With that said, if it's not readily available and only available via 
modification, someone more knowledgeable had good reason. I'll think of 
a different approach.

Thanks again!

That's probably a result of what drove MapServer development early on.
MapServer itself is just a binary (CGI/FCGI) that can do stuff as simple as
making simple inset maps or scalebars to distributing maps and data using
OGC services with plenty of variations in between. Each call is discrete
and there are no long running processes. A single deployment could serve
dozens of wide-ranging purposes and in that situation a catalog makes no
sense. Those "purposes" often only make sense with the context of the
application that uses them. Closest thing to a catalog would be
GetCapability responses. Then of course you have MapScript applications
that would be difficult, if not impossible, to identify as being related to
MapServer.

Hello-

 

I'm trying to setup a WMS layer that is reading a raster table in PostGIS.
I am loading NOAA Global Hydro Estimation data in a single table (tiled) and
have a field that contains the datetime for the raster.  I followed the
examples here: 

 

https://postgis.net/docs/RT_FAQ.html#idm29732

 

In my case I would like to use the "where" statement to filter the raster
tiles, but the 'where' statement only seems to work with the 'rid' field
(e.g. rid=123).  Based on the example in the PostGIS docs, it looks like it
should theoretically work.  I tried the "FILTER" in the map file, but I
assume that only works with vector data since it did nothing.         

 

Does anybody know the trick to filter tiled raster data from a PostGIS
raster table?  

 

Any help is greatly appreciated!  

 

Cheers, 

 

BW

Can you access/filter the data outside MapServer with only GDAL? Might be
easier to battle one piece of software rather than two.

Message-ID: <1ca3c52a-ed8b-9f33-8604-7caccf197e4d@gatewaygeomatics.com>

On behalf of the MapServer community, and its PSC, we wish to send our 
condolences to the family of Olivier Courtin, as we have sadly learned 
of his unfortunate passing.

Olivier was a big part of the MapServer and Open Source community, 
through his work as the creator of the TinyOWS project, as a core 
contributor to PostGIS, as co-founder of the company Oslandia, as a 
manager with Camptocamp, and of course as a lead organizer of the 2016 
OSGeo Code Sprint in Paris.  Recently Olivier founded the open company 
DataPink, and created the open framework neat-EO.

Olivier through his work through various companies and projects helped 
fund conferences, sprints, functional additions to projects and, of 
course, contributions of code and support.  Olivier was a significant 
driver of those relationships, even given his quiet demeanor.

First priority is his family and friends (we have already reached out to 
his family to send our thoughts and offer assistance).  Some of us are 
quiet, and still processing this unfortunate news.

This is of course not the time to discuss software issues, but the 
MapServer PSC will tackle this shortly in the upcoming PSC meeting.

Again, our sincere thoughts to his family and close friends.

Olivier, we miss you already.

-on behalf of the MapServer PSC

Hi Eric!

First sorry for my poorly formatted response, in fact your email never 
made it to my inbox, as the email server for this list is hosted on a 
machine that was recently tagged on a spam 'blacklist' (see 
https://trac.osgeo.org/osgeo/ticket/2475), so I'm piecing together a 
response to you manually ha.

Regarding upgrading to MapScript SWIG, the MapServer migration guide 
actually lists 2 very important points regarding PHP that must now 
always be followed (see 
https://mapserver.org/MIGRATION_GUIDE.html#mapserver-7-2-to-7-4-migration). 


    1) all of your PHP scripts (that leverage MapServer objects and 
functions) must now always first include the generated 'mapscript.php' 
file containing MapServer constants:

        // required SWIG include (contains MapServer constants for PHP7)
        include("C:/ms4w/apps/phpmapscriptng-swig/include/mapscript.php");

    2) take note of the change in how to declare your new objects with 
the "new ..Obj" syntax :

        // open map
        $oMap = new mapObj("C:/ms4w/apps/phpmapscriptng-swig/


Regarding the required file 'mapscript.php', if you are compiling 
MapServer yourself, it will be generated in your build folder alongside 
the generated 'php_mapscriptng.so' (such as in

     /mapserver-master/build/mapscript/phpng/

By odd chance, earlier today I added a working example for how to create 
a new point object (with an inline feature) through PHP mapscript SWIG: 
https://ms4w.com/trac/wiki/SWIGMapScriptNewLayer

The important parts of the example PHP script are:

   <?php

   // define variables
   define( "MAPFILE", "C:/ms4w/apps/phpmapscriptng-swig/sample.map" );

   // required SWIG include (contains constants for PHP7)
   include("C:/ms4w/apps/phpmapscriptng-swig/include/mapscript.php");

   // open map
   $oMap = new mapObj(MAPFILE);

   //******
   // create new point layerObj
   //******
   $oPointLayer = new layerObj($oMap);
   ...

   // draw map
   $oImage = $oMap->draw();

   ?>

Hope that makes a little sense ha!

Hi,

I'm not sure if you have a custom template for each layer already, or if this something you want to avoid?

I'm guessing ideally you want to be able to change the LAYER - TEMPLATE via the URL?
Although this is not listed in the docs at https://mapserver.org/cgi/runsub.html#parameters-supported looking at the source I think it can be replaced via a URL. 

You can also set a CLASS TEMPLATE via the URL, and maybe have a different CLASS for each INFO_FORMAT and select it with GetStyles. 

Changing the format filename for each layer might be a possibility?
https://mapserver.org/cgi/runsub.html#parameters-supported
OUTPUTFORMAT: FORMATOPTION: FILENAME (must have a MAP VALIDATION pattern)

Hi,

I am using the query below to return a hydrograph of a region (using
POSTGIS). This query works perfectly when I use it in pgadmin. With the
mapserver, the connection with the client is lost. It records a query that
shows no errors in SQL, just shows that the connection has lost. Why is
that?

DATA "geom FROM (
         SELECT
            hidro.fid, hidro.name, ST_Intersection(gcc.geom, hidro.geom) AS
geom
          FROM
            vector.hidrography AS hidro,
            vector.gcc AS gcc
          WHERE ST_Intersects(gcc.geom, hidro.geom) AND gcc.name = 'GRANDE'
) as subquery USING UNIQUE fid USING SRID=4326"

Thanks in advance

Hi,

What client are you using?
How long does the query take to complete?
It is likely the client stops waiting for a response.

Hi Fernando,

I would try using the shp2img utility at the commandline, and set CONFIG 
"CPL_DEBUG" "ON" in your mapfile (see 
https://mapserver.org/optimization/debugging.html#step-3-turn-on-cpl-debug-optional) 
and then execute:

   shp2img -m mymap.map -o ttt.png -all_debug 5

The full query should be listed there in the response, which you can 
then paste into the psql commandline, and manually execute the same 
query to your database.

PS. hello to my friends in Brasil!

Hi,

This issue is related to:

  *   https://github.com/mapserver/mapserver/commit/722716c49de2399f54b275ab31437f0e8c92cd63
  *   https://github.com/mapserver/mapserver/commit/4c2aeb4bbd229723d8ea67c337cf02350575b2ae

The issue is that when I try to visualize (via WMS) a layer with a NetCDF data file with longitude from 0? to 360? in EPSG:3857, there is a sliver around longitude 0? where no data is displayed.

We already had that issue with the same files using EPSG:4326 and it's been fixed in MapServer (see merge request above).

Here is where you can find example files: https://dd.weather.gc.ca/model_giops/netcdf/lat_lon/2d/00/003/CMC_giops_votemper_depth_0.5_latlon0.2x0.2_3h-mean_{yyyymmdd}00_P003.nc

Subject: [mapserver-users] Problem with Python MapScript queryByRect
Message-ID: <35fd8e93-e9c2-240b-154f-4c231c4c0d00@gmail.com>

Hi,

I am reviving a Python 2 MapServer MapScript app that used to work 7 
years ago (and still is in old deployment) but stuck in some MapScript 
calls that fail but also throw no Exceptions.

Purpose of the app "MapGlow" [1] is to generate a WMS-heatmap triggered 
by specific STYLE parameters. When no heatmap STYLE is requested 
requests are delegated to map_file.OWSDispatch() etc. The latter works 
fine so the overall setup/stack/mapfile is working. Using MS 7.6.0 in 
Docker (compose) with Lighttp, FastCGI, WSGI, flup.

It is only when  layerObj.queryByRect() is called, a HTTP 500 is 
returned after a FastCGI hard error, no means to catch an Exception. The 
passed MapFile and Rect objects seem ok. Also I noticed that 
layerObj.metadata had 0 items. I can see that I have proper SWIG objects 
like
<mapscript.layerObj; proxy of <Swig Object of type 'layerObj *' at 
0x7fded06b1de0> >
If only I could get a hint, a MapFile setting, maybe some log output or 
debug flag I can set? The WIP is on GH, I can point at the failing line 
[2] but the code is
quite involved (mind, my first Python 7-9 years ago):

Hi Louis-Philippe,

With much kind respect, the test case that you provided was not very 
simple, so I had to spend much effort to create a tiny test case, that 
contains one of your NetCDF files, and a small mapfile that simply 
reprojects the file into EPSG:3857 (without WMS etc.).  The small test 
case contains a single shp2img command to replicate the issue (in a file 
'commands.txt') which you can download at 
https://gatewaygeomatics.com/dl/netcdf-2020-06-26.zip

The issue that you report, of a sliver (no data) in the map when 
reprojecting to 3857, is visible in the resulting map images in the live 
demo at: 
https://demo.gatewaygeomatics.com/cgi-bin/mapserv?MAP=/home/apps/netcdf/2020-06-26/netcdf-test.map&MODE=browse&TEMPLATE=openlayers&LAYERS=all 
  (this server is running MapServer-master)

This should be filed as a new ticket at 
https://github.com/mapserver/mapserver/issues and point to this test 
zipfile.

Have a nice weekend,

-jeff

I got somewhat further: it appears I get a SEGFAULT when calling any 
MapScript query() method. This is also what FastCGI receives (signal 11).

For example, bash-ing into the Docker Container and execute MapScript 
Python:

$ python
Python 2.7.16 (default, Oct 10 2019, 22:02:15)
[GCC 8.3.0] on linux2
 >>> import mapscript
 >>> map = mapscript.mapObj('/app1/config/mapserver/app1.map')
 >>> layer = map.getLayerByName('nlpubs')
 >>> layer.name
'nlpubs'
 >>> len(layer.metadata)
0
 >>> res = layer.queryByAttributes(map, 'Name', 'Lef', 
mapscript.MS_MULTIPLE)
Segmentation fault

But getting number of Features is ok:
 >>> layer.getNumFeatures()
GNM: GNMRegisterAllInternal
GNM: RegisterGNMFile
GNM: RegisterGNMdatabase
GDAL: GDALOpen(/app1/data/pubs, this=0x557ace611b90) succeeds as ESRI 
Shapefile.
Shape: DBF Codepage = LDID/87 for /app1/data/pubs/osm-nl-pub.shp
Shape: Treating as encoding 'ISO-8859-1'.
GDAL: GDALClose(/app1/data/pubs, this=0x557ace611b90)
2864

The LAYER def is
LAYER
     NAME nlpubs
     STATUS default
     TYPE POINT
     PROJECTION
       "init=epsg:4326"
     END

         SYMBOL "circle"
         SIZE 10
       END
     END
END

Data is a shapefile, but GeoJSON also fails. Also strange that 
layer.metadata is empty. Like said when I delegate any incoming OWS req 
to map.OWSDispatch() I get proper results for all WMS requests, in 
particular GetMap with styled output.
The base Dockerfile used is at:
https://github.com/PDOK/mapserver-docker/blob/master/Dockerfile from
which I derived my Dockerfile:
https://github.com/justb4/mapglow/blob/master/Dockerfile

Maybe there is some mismatch in lib versions?

Again thanks. Best,

Subject: [mapserver-users] Differerent output format for GetFeatureInfo

If your data is very standardized I can see where this would be helpful. I
think if the layer attribute was interpreted as a regex then that might do
the trick. I?d advocate adding another attribute though to avoid a
regression since layer names commonly contain characters that would be
problematic in a regex. Something like ?layerPattern?. With that you could
do:

  [resultset layerPattern=?.?]
    ...
  [/resultset]

and it would apply to all layers. Note there is also include support in
templates so you can use a common presentation over and over even if you
had to define a resultset for each layer. So something like:

  [resultset layer=?l1?]
    [include file=?common.html?]
  [/resultset]
  [resultset layer=?l2?]
    [include file=?common.html?]
  [/resultset]

This could be a candidate for 7.6.1 I suppose.

Subject: [mapserver-users] Problem with Python MapScript queryByRect

Solved, there was some kind of mismatch probably with library versions 
from multi-stage Docker builds/copies.

Made a new Dockerfile from buster-slim with standard Mapserver (7.2.2 ) 
and Lighttpd and apart from some new MapScript syntax, all works!

The Dockerfile is nice and small (296MB uncompressed), works 
out-of-the-box with FastCGI/WSGI, albeit somewhat older MS version:
https://github.com/justb4/mapglow/blob/master/Dockerfile

Best,

Just

When I run the query in pgadmin4 query tool it works correctly.
SELECT
hidro.fid, hidro.name, ST_Intersection(gcc.geom, hidro.geom) AS geom
FROM
vector.hidrography AS hidro,
vector.gcc AS gcc
WHERE ST_Intersects(gcc.geom, hidro.geom) AND gcc.name = UPPER('grande')

When I run the same query in mapfile it does not work (it returns only
null).

DATA "geom FROM (
SELECT
hidro.fid, hidro.name, ST_Intersection(gcc.geom, hidro.geom) AS geom
FROM
vector.hidrography AS hidro,
vector.gcc AS gcc
WHERE ST_Intersects(gcc.geom, hidro.geom) AND gcc.name = UPPER('grande')
) as subquery USING UNIQUE fid USING SRID=4326"

The difference is "as subquery USING UNIQUE fid USING SRID=4326"

When I run shp2image the query returns:

...

I didn't find out why the mapserver is not executing this query correctly.

Hola, Fernando,
I don't know what's really going on but despite if this is a GDAL error or something else, I suggest you to try the following in the MAP file LAYER section:
