[Qgis-user] QGISWebserver and PostGIS-Layer

[Bernhard Ströbl]

Hi Albin,

try
http://myserver/cgi-bin/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&FORMAT=image/png&CRS=EPSG:4326&WIDTH=500&HEIGHT=500&LAYERS=mypostgislayer&BBOX=12.96,47.79,12.98,47.81 


as a major change from 1.1.1 to 1.3.0 is the exchange of x and y 
coordinates or use VERSION=1.3.0 and exchange x and y coordinates of the 
BBOX

if I understand you correctly you get an image as reply but the image is 
all white. So the server is running ok but there are no data in the 
place for which you request the map.
