[mapserver-users] TR: Blank map

[Rahkonen Jukka]

Hi,

Sorry, I fear I cannot say much more than try to make the test as simple as possible in the beginning and if something happens to work, complicate things thereafter.  Shp2imp is an excellent start.  What might be more simple in the WMS request is using &FORMAT=image/png and WMS version 1.1.1. Leave out the backgroundcolor and transparent. Check with ogr2ogr that the bounding box in the request is OK and that there for sure are some data inside the bounding box.  I guess you have already checked that there are no active minscale/maxscale settings hiding data at some scales.
