My thoughts:
1) MS4W is preconfigured for the following imagepath and imageurl
settings, in case you are not aware:
IMAGEPATH "/ms4w/tmp/ms_tmp/"
IMAGEURL "/ms_tmp/"
2) I assume that the postgis layer is in the same projection as the
local layer?
- test this by setting the extents to the postgis layer and removing
the local layer from the mapfile
3) use ogrinfo to verify the extents of the postgis layer
e.g. ogrinfo -ro PG:"host=127.0.0.1 user=postgres dbname=gmap"
yourlayername --summary
4) make sure you specified an srid when you loaded the data into postgis
e.g. shp2pgsql -s 42304 province.shp province > province.sql
5) here is my my working tiny mapfile with a postgis layer:
#
# Start of map file

END
CLASS

OUTLINECOLOR 199 199 199
END
END
END # layer
END # Map File
6) test your mapfile with the shp2img utility (http://mapserver.gis.umn.edu/docs/reference/utilityreference/shp2img
)
e.g. shp2img -m gmap75_postgis.map -o test.png -map_debug 3

Hello to everyone,
I have an (already mentioned but - as it seems to me - not yet solved)
problem concerning PostGis used with MapServer.
My application can show shape files but not postgis-files. There are
no
output files (png) generated for this layer.
Below is my mapfile.
I would be very pleased if anyone can give me some usefull hint.
Thanks a lot,
Susanne Kalliany
