[mapserver-users] rfc43 gtile returning blank images, while WMS works

[akrherz at iastate.edu]

Hi Mapsurfers,

I have been messing around with RFC43 (GTile support) and only seem to get 
blank tiles.  For example, here is a GTile request

http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi?layers=nexrad-n0r-900913&mode=tile&tilemode=gmap&tile=0+1+2

I then turn that URL into an equivalent WMS request:

http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi?width=256&height=256&FORMAT=image/png&srs=EPSG:900913&request=GetMap&service=WMS&version=1.1.1&layers=nexrad-n0r-900913&bbox=-20026376.390922,11131.949078,-10029886.119078,10007622.220922

and get data.  Any ideas what I may be doing wrong?


thanks!
