[Geomoose-users] ND Aerial Photo WMS

[Brent Fraser]

Paul,

   I'm not sure why it fails with the webmercator demo.  It seems that mapserver 
is not re-projecting the image from the WMS server; maybe it thinks the image it 
requests from the WMS server is returned in EPSG:900913 (it's in 4326).

I ran the map file in shp2img.  pj_transform issues a message, which could be a 
clue (or not):


shp2img -m ND_Aerial2005.map -all_debug 5 -e -11585782.520684 6098659.6770264 
-11573528.70959 6108133.0912178   -o test5.tif

At this point I'm at a loss....
