My data is in WGS84 Major Auxiliary Sphere (as outputted by ArcGIS)..
EPSG:3857
- Using this<http://rinnerweb.arts.ryerson.ca/cgi-bin/mapserv.exe?map=/ms4w/Apache/htdocs/moot2_dev/hii_railroads.map&REQUEST=GetMap&WIDTH=500&HEIGHT=500&LAYERS=HII_railroads&VERSION=1.1.1&SRS=EPSG:3857&bbox=-10995797.347,5031174.730,-7855157.347,7815054.730&MAPUNIT=DecimalDegree&FORMAT=image/png&ClientId=&CLIENTMODE=TiledWmsRasterSource>GetMap
request, I have verified that my data is in fact queryable
So I changed a few settings in my tilecache.cfg as so based on the GetMap
query:
[HII_railroads]
type=WMS
url=http://141.117.104.183/cgi-bin/mapserv.exe
mapfile=C:/ms4w/Apache/htdocs/moot2_dev/hii_railroads.map

Still no luck <http://rinnerweb.arts.ryerson.ca/moot2_dev/>, darn.
You can see that layer hii_6 doesnt produce any images and I am given this
error when I explore the
url<http://rinnerweb.arts.ryerson.ca/cgi-bin/tilecache.cgi?LAYERS=HII_railroads&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A3857&BBOX=-10995797.347,6283519.00125,-9743453.07575,7535863.2725&WIDTH=256&HEIGHT=256>to
