Re: [Qgis-user] QGIS Server a GetFeatureInfo request problems. Not sure what I am missing.
Bernhard - Thanks for the info. I am not sure if GeoServer can handle
cascading GetFeatureInfo requests but the typical scenario would not warrant
that, meaning the path would be Client(OpenLayers) -- GeoServer -- PostGIS
whereas using QGIS Server to display QGIS project files would add that extra
layer. So, you are right in that it would seemingly work if the QGIS Desktop
layers were layers based on a direct DB connection, but the point of using
something like GeoServer is to abstract and consolidate GIS layers into a
single location for users to access. Depending on your type of user, they may
not know (or have a need for) database connection information. They may not
know where shape files or GeoTiffs are located. GeoServer is like ArcCatalog
where all types of GIS data (database, files like Shape and GeoTiff, WMS, WFS,
etc) can be managed as layers and then clients (like QGIS Desktop or
OpenLayers) need only come to GeoServer to get what they need. Unfortunately
for us, we can't remove GeoServer from the architecture, so if you are correct
about QGIS Server not being able to cascade these requests, we will need to
think of some other solution. I will create another mailing list question
specifically for this question. Thanks for you insight - Peter

Hi Peter,
AFAIK QGIS server does not cascade GetFeaureInfo requests for cascaded
WMS layers - does geoserver do this?
So if you need GetFeatureInfo you have to load the layers directly from
source (PostGIS) into your QGIS project (makes more sense anyway)

Re: [Qgis-user] QGIS Server a GetFeatureInfo request problems. Not sure what I am missing.
Bernhard - Yes, excellent point. There really is no point of having both a GeoServer and QGIS Server as in-house WMS servers. For our QGIS Desktop client, GeoServer is the server we are using, so QGIS Server does not even enter the picture. The reason why QGIS Server is now entering our view scope is that we needed a way to serve up our QGIS Desktop project files (.qgs files) over WMS and QGIS Server apparently does that. We need to do that because we have a .Net application where we need a control that can view the QGIS project files since QGIS does not have a .Net API to essentially create a QGIS .Net control. So, if QGIS Server can serve up the project files using WMS, we can possibly create a .Net control (like a browser control using OpenLayers or DotSpatial) to consume the WMS. Our situation may not be typical but it is what it is for now. -Original Message- From: Bernhard Ströbl bernhard.stro...@jena.de Sent: Jan 23, 2014 8:51 AM To: Peter Len petera...@earthlink.net Cc: qgis-user@lists.osgeo.org Subject: Re: [Qgis-user] QGIS Server a GetFeatureInfo request problems.

It is of course the right way to use _one_ WMS server; in your case this is geoserver. You can point any WMS (or WFS?) client to this server, like QGIS desktop or OpenLayers. IMHO there is no need for QGIS server in this setting. Would be a different story though, if geoserver was located outside and you are using QGIS server to cascade certain of its layers inhouse (thus QGIS would be your _one_ WMS server).

[Qgis-user] QGIS Server and cascading GetFeatureInfo requests
This is a specific follow-on question from an earlier post (QGIS Server a GetFeatureInfo request problems. Not sure what I am missing). There were several good, and helpful, responses to that posting which has led to wanting to verify a specific capability, or lack thereof. In the earlier posting, I was having problems getting feature information when I loaded my QGIS project file layers in an OpenLayers client using WMS. The project file contained layers that were created in QGIS as a WMS service call to our GeoServer, so the route was: OpenLayers -- QGIS Server (QGIS Project File) -- GeoServer -- PostGIS Using Firebug, I got the GetFeatureInfo request URL coming from OpenLayers. When I pasted this directly in the browser, I received the HTML response but it contain no feature info. I then used a project file where the layers were direct connections to the database: OpenLayers -- QGIS Server (QGIS Project File) -- PostGIS In this scenario, I was able to get the feature info. After posting these findings, the response was that QGIS Server was not cascading GetFeatureInfo requests. Not sure how that exactly works, but it brings up a problem for us and I am looking for a definitive answer to the question of whether QGIS Server can get/send GetFeatureInfo requests on to another server, like GeoServer. Thoughts? - Peter ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] QGIS Server a GetFeatureInfo request problems. Not sure what I am missing.
Alex - Good idea with the Firebug. This is what I found The first URL is
the one being sent to the QGIS Server (returns no results) and the second one
is the URL that gets sent to GeoServer (returns results):
http://localhost:8090/qgis/qgis_mapserv.fcgi.exe?LAYERS=location_viewQUERY_LAYERS=location_viewSTYLES=SERVICE=WMSVERSION=1.1.1REQUEST=GetFeatureInfoBBOX=-215.683594%2C-59.238281%2C215.683594%2C59.238281FEATURE_COUNT=10HEIGHT=337WIDTH=1227FORMAT=image%2FpngINFO_FORMAT=text%2FhtmlSRS=EPSG%3A4326X=650Y=106
http://localhost:8080/geoserver/Postgres/wms?LAYERS=Postgres%3Alocation_viewQUERY_LAYERS=Postgres%3Alocation_viewSTYLES=SERVICE=WMSVERSION=1.1.1REQUEST=GetFeatureInfoBBOX=-215.683594%2C-59.238281%2C215.683594%2C59.238281FEATURE_COUNT=10HEIGHT=337WIDTH=1227FORMAT=image%2FpngINFO_FORMAT=text%2FhtmlSRS=EPSG%3A4326X=650Y=106
You can see that both URLs contain the same parameters and values, except that
the call to the GeoServer contains a workspace name with the layer name. Just
as a test, I added the workspace name to the QGIS Server URL but that simply
failed because it was an incorrect reference. The QGIS Server URL is going to
a QGIS project file which contains a layer that comes from my GeoServer. So,
in the end, we are talking about the same data set for both URLs, except one is
going through QGIS Server as a pass-through to the GeoServer.
So, given that there does not seem to be an issue with the URL or its
parameters per se, I would have to believe that there must be some something
within the QGIS Server configuration. I understand that QGIS Server is
supposed to handle GetFeatureInfo requests so I must be missing something in
the QGIS Server configuration, some extra parameter in the URL, or
Any new thoughts from the QGIS Server gurus?

Re: [Qgis-user] QGIS Server a GetFeatureInfo request problems. Not sure what I am missing.
Andreas - I had previously used the map parameter per an earlier response, but it didn't help. I have two test versions of this. One that does tell QGIS Server to use a project file at the path listed in the map parameter and one that does not list a map parameter, in which case QGIS Server uses the first project file it finds in its bin directory. I have been doing my main testing using the project in the bin directory to eliminate any problems that may be due to adding the map parameter. When not adding the map parameter, QGIS Server serves up the correct layer info for display in my OpenLayers, it just seems to be a problem when asking for the GetFeatureInfo. - Peter -Original Message- From: Andreas Neumann a.neum...@carto.net Sent: Jan 21, 2014 8:49 AM To: qgis-user@lists.osgeo.org Subject: Re: [Qgis-user] QGIS Server a GetFeatureInfo request problems.

Re: [Qgis-user] QGIS Server a GetFeatureInfo request problems. Not sure what I am missing.
Forgot to mention one thing. Even though QGIS Server is not sending back any results from the request, it does send back an HTML response that just contains an empty table, but it does reference that this is a GetFeatureInfo result and has the HTML table lined up to add results if it had any. The response is listed as: HEAD TITLE GetFeatureInfo results /TITLE meta http-equiv=Content-Type content=text/html;charset=utf-8 /HEAD BODY TABLE border=1 width=100% TRTH width=25%Layer/THTDlocation_view/TD/TR /BR/TABLE BR/BR /BODY So, it does seem that QGIS Server understands that it got a request for feature info and it created a valid response.

An interesting update to this.. So the scenario that has not been working
looks something like this:
OpenLayers -- QGIS Server -- QGIS Project File -- GeoServer -- PostGIS
I decided to run a test and create a new project file with the same layer
(location_view) but this time create a PostGIS layer rather than a WMS layer
going to GeoServer. In this case, the scenario looks like:
OpenLayers -- QGIS Server -- QGIS Project File -- PostGIS
So, given that, it appears that something else might be going on. QGIS Server
does seem to be serving up feature information, but not in all scenarios. Not

from OpenLayers directly to GeoServer for feature info works fine.

latest OSGeo4W installer. I was testing an OpenLayers client to view a
QGIS Desktop project file over WMS from the QGIS Server. All seems good
with that. For example, my OpenLayers code to get this looks like:
var url = http://localhost:8090/qgis/qgis_mapserv.fcgi.exe;;
var layer = new OpenLayers.Layer.WMS( Main Layer, url, {
layers: 'table_poly,location_view',
format: 'image/png',
},
{
buffer: 1,
isBaseLayer: true,
graphicZIndex: 0,
}
);
map.addLayers([layer]);
With the above, I can view my layers within OpenLayers. My next test was
to see if I could get the feature info from items on my layers. I found
an example of how to make this call in OpenLayers and it looks like:
var info = new OpenLayers.Control.WMSGetFeatureInfo({
url: url,
title: 'Identify features by clicking',
queryVisible: true,
eventListeners: {
getfeatureinfo: function(event) {
alert(Got feature info);
}
}
});
map.addControl(info);
info.activate();
When I tried this, I didn't get anything except a spinning cursor. I then
tried another test to see if that was the correct way to ask for feature
info so I changed the URL for the layers to get the layers from my
GeoServer rather than from QGIS Server (the project file got these layers
initially from GeoServer so we are talking about the same layer source).
That worked just fine and I was able to get individual feature
information. After switching back to point to my QGIS Server I started to
look at the Apache web server logs and the GeoServer output screen. The
Apache logs didn't list anything related but the GeoServer console listed
the following:
WMS GetFeatureInfo in OpenLayers does in fact work with QGIS Server with
one trick, vendorParams you need to specify the qgs file to reference.
infoControls = {
click: new OpenLayers.Control.WMSGetFeatureInfo({

This occurred just after clicking on my OpenLayers map, which in turn triggered
the WMSGetFeatureInfo request. I noticed that there was no reference to
GetFeatureInfo. So... I am not sure what to make of this. Should my
OpenLayers call be something different? Does QGIS Server not serve up features
from layers within a project file? I had found some references concerning a
problem with QGIS Server and GetFeatureInfo calls (Bug #8656) but the request
URL listed seemed to be something different than my scenario via OpenLayers and
to a project file layer.
Any thoughts?

Re: [Qgis-user] QGIS Server a GetFeatureInfo request problems. Not sure what I am missing.
Alex - Thanks for the reply. Initially, I was trying to run this test using a
project file where I used the map parameter in the layer definition. This
got the layers to display within OpenLayers but the GetFeatureInfo request was
not working. I then went back to having the project file in the QGIS Server's
bin directory so that no file name has to be listed. That is the setup I was
using in the examples I provided. I went back and ran another test when using
a file at some path and used your vendorParams example, but the outcome is
the same.

Re: [Qgis-user] QGIS Server and qgs project files with ratser layers issue
Marco, Interesting. I never thought about that, but it would make sense. The only layer not displayed was the one that came from the net (as opposed to the layers that came from our database). That would explain why it also did not display in ArcMap and OpenLayers when accessed via QGIS Server but if you created a WMS layer directly to the web address where the layer was, it would be displayed (ie their server could serve it up but no my QGIS Server). Good catch.

[Qgis-user] QGIS Server project files served to OpenLayers question
I have been playing with the QGIS Server and looking at how it serves up QGIS Desktop project files using WMS. My initial tests were to create a new WMS layer in QGIS Desktop which used a URL to serve up a project file. When I did this, QGIS Desktop listed all of the layers within the project file to choose from. I could pick and choose which ones to add to the new project file. I also found that when I selected a feature layer (feature points from our database), the Identify Features tool showed the selected feature metadata which meant that although the layer was served up over WMS, it still understood it to be a feature layer. The next step was to try to load the project file in OpenLayers (using an OpenLayers.Layer.WMS object). When trying this, I found the following: 1) I needed to list the WMS layer as an image 2) I could give the file path to the project file using the map option 3) I had to list the name of the layer. When I used a GetCapabilities URL in the browser for a given project file, I see that there is always a Layer with the name of the project file and SOMETIMES there is another layer name for one of the actual layers within the project. I have yet to see a GetCapabilities for a project file that listed all the layer names. In any case, if I used the project file name as the layer name option, it would indeed display everything on the OpenLayers map. I guess as expected, because the layer was displayed as an image and as a single layer, there was no access to the feature metadata (like there is with the Feature Identify tool in QGIS Desktop). The layer was simply a WMS image. Based on this, my conclusion is that there is no way to select and view individual features from my QGIS project file when the client is a browser-based mapping API like OpenLayers. Does this sound about right, or am I missing some other way to have OpenLayers understand that there are actual features, like points, lines, and polygons?

Jurgen, Thanks for the reply. The OSGeo4W installer does not come with a mod_fcgid.so file. I have seen some references that seem to indicate that maybe the Windows install should now work with FastCGI, but the installation doesn't include it. A regular Apache Web Server (outside of OSGeo) install does not include it either. I tried downloading the module separately but I got an error when trying to start Apache so it either wasn't the right one to use or it still can't be used on Windows. - Peter -Original Message- From: Jürgen E.

When I went to start apache, I get the following error: C:\OSGeo4W\apache\binhttpd.exe -k start -n Apache OSGEO4W Web Server [Wed Jan 15 10:45:39 2014] [warn] module cgi_module is already loaded, skipping Syntax error on line 4 of C:/OSGeo4W/httpd.d/httpd_qgis.conf: Invalid command 'DefaultInitEnv', perhaps misspelled or defined by a module not included in the server configuration The conf file looks like: #LoadModule fcgid_module modules/mod_fcgid.so LoadModule cgi_module modules/mod_cgi.so DefaultInitEnv QGIS_PREFIX_PATH C:\OSGeo4W\apps\qgis DefaultInitEnv TEMP C:\Users\pal1\AppData\Local\Temp DefaultInitEnv PATH C:\OSGeo4W\bin;C:\OSGeo4W\apps\qgis\bin;C:\OSGeo4W\apps\grass\grass-6.4.3\bin;C:\OSGeo4W\apps\grass\grass-6.4.3\lib;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem Alias /qgis/ C:\OSGeo4W/apps/qgis/bin/ Directory C:\OSGeo4W/apps/qgis/bin/ #SetHandler fcgid-script SetHandler cgi-script Options ExecCGI Order allow,deny Allow from all /Directory There are three lines that use the DefaultInitEnv declaration and it will bomb out on the first one that is listed (I switched the order to see if it was one in particular). So, does anyone know where DefaultInitEnv is suppose to be defined as per the error message. Not sure what I may be missing from this installation that is creating this failure.

[Qgis-user] Problems loading/accessing QGIS Server.... what am I missing?
I am using QGIS and wanted to install the QGIS Server on a Windows 7 box. I was looking at the following pages for how to do an install on Windows 7: http://hub.qgis.org/projects/quantum-gis/wiki/QGIS_Server_Tutorial http://anitagraser.com/2012/04/06/qgis-server-on-windows7-step-by-step/ I got the installer from http://download.osgeo.org/osgeo4w/osgeo4w-setup.exe. When I ran the install, I did an advanced installation and selected to install the Apache Webserver and the QGIS Server. The instructions went on to say that for Windows installs you must change FastCGI to just the CGI in the httpd_qgis.conf file. So now the httpd_qgis.conf references: LoadModule cgi_module modules/mod_cgi.so SetHandler cgi-script After another change in that conf file to change DefaultInitEnv to SetEnv (using DefaultInitEnv threw errors). After that, I was able to start the Apache web server and was able go to the default page. I noticed that the page indicated that there was only 1 osgeo4w application installed (phpinfo). The instructions then indicated that the following GetCapabilities call should work: http://localhost:8090/qgis/qgis_mapserv.fcgi.exe?SERVICE=WMSVERSION=1.3.0REQUEST=GetCapabilities When I ran this in the browser, it indicated that there was an error. The error log file stated: Premature end of script headers: qgis_mapserv.fcgi.exe This made me think that there was some mismatch between changing the conf file to use cgi rather than fcgi. There is no qgis_mapserv.cgi.exe, however. Not sure what I am missing here. Both sets of instructions were followed and they both indicate it should be working. Does anyone know what I may be missing? Thanks - Peter ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] Problems loading/accessing QGIS Server.... what am I missing?
So, this was fixed by copying all of the .dll libraries from c:/OSGeo4W/bin to c:/OSGeo4W/apps/qgis/bin. Not sure why none of the references I used indicated this, so I am not fully comfortable that it is truly working. I have been able to load a QGIS Desktop project served up by QGIS Server to both ArcMap and QGIS so at least that is a start. -Original Message- From: Peter Len petera...@earthlink.net Sent: Jan 15, 2014 1:13 PM To: qgis-user@lists.osgeo.org Subject: [Qgis-user] Problems loading/accessing QGIS Server what am I missing?

[Qgis-user] Is this list also used for QGIS Server questions?
I am looking at QGIS Server and came across a question but cannot find a forum/list serv to post questions to. Does this forum also deal with QGIS Server questions or is there another area that I could not find?

[Qgis-user] Identify Features popup and viewing feature metadata question
I am using QGIS v2.0.1 and am also using PostgreSQL/PostGIS as well as GeoServer. In my PostgreSQL, I have a feature table that contains an ID, title, and point geometry. I have published the table as a WMS/WFS via GeoServer. In QGIS, I added a layer to the feature table with a direct connection through the Add PostGIS Layer and I also added another layer to the feature table through the AddWFS Layer (which goes through GeoServer). When I click on the Identify Features icon and click on a feature that is on my PostGIS direct connection layer, I can see the ID and Title for that feature in the popup window. If however, I click on the same feature but is in the WFS layer, I don't get that other metadata. I only see the coordinates for the feature. I am new to QGIS and these types of geospatial tools so I am not sure what the difference is. Am I not seeing the other metadata fields when working with the WFS via GeoServer because you don't get the other field data with that service? or is it an indicated that I am not properly registering or accessing the layer over WFS? or ??? Any thoughts would be greatly appreciated - Peter ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] Where can I find a WMS gloabl map??
I am using QGIS 2.0.1 and am looking for a URL for a WMS server that will serve up a global map of any kind. I thought this would b easy to find but am running into a wall on this. No sure what I am missing. Can anyone give me a WMS server URL that has a world map of some sort?
