Hello,
I am currently working on a project where I'm trying to use Mapserver as a WMS client, intending to have Mapserver handle the overlaying of data for me. The WMS service I'm going to be using one licensed from the National Land Survey of Finland. This server only supports HTTPS connections and requires Basic Authorization to get data from the service. This may prove to be an issue for me in the future, but at the moment I'm having (what I suspect to be) a different problem. When I test my Map file, which to the best of my (currently limited) knowledge of Mapserver, should work, I only get entirely white images back from the mapserv binary. I've not yet figured out how to get mapserv to do verbose logging, but the logging it does so far does not show me what the issue might be. I've been trying to get it to work on linux, but then when it didn't I tried it on my local windows machine as well. Both machines display the same white image. The output of my mapserv -v invocations: On Linux: MapServer version 5.0.2 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=GEOS INPUT=EPPL7 INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE On Windows: MapServer version 5.0.2 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS _SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE The map file I'm using can be found at the following location: http://www.gonewacko.com/work/finland.map For more information about the capabilities of the WMS Server I'm trying to connect to, I've uploaded the results of a GetCapabilities request here: http://gonewacko.com/work/GetCapabilities.xml (Most of the text is in Finnish; Which I don't actually understand myself, but luckily it's not too relevant). The URL I've been using to test it has usually just been http://example.com/cgi-bin/mapserv?map=/path/to/finland.map <http://example.com/cgi-bin/mapserv?map=/path/to/finland.map&mode=map> &mode=map. My theories are - The map has been set up in such a way that mapserv finds it's not within the area I'm requesting, and as such does not attempt to render it. - The map has just been set up incorrectly (most likely) Note that the only files I have are the map file. I do not have any shape files or anything of that nature. And apart from the censored login information in the URLs, the map file is available in its entirety. Also note that I've tried replacing the WMS URLs with something that is not a https url (i.e. a normal http url), as well as omitting the authorization data. It still wouldn't send a request to the URL. Can anyone shed some light on what I'm doing wrong? Thanks in advance. Best Regards, Stijn Gijsen
