After getting all the projection sections into my .map file without any correctly-drawn tiles, I've given up on tilemode for now and am trying out tilecache with MapServer's WMS. However, it appears that EPSG:900913 is not known in my system. On a Linux install, where is the list of projections/WKT?
I've tried using upper and lower-case namespace (epsg and EPSG) to no avail. I get the following error through tilecache when it attempts to hit my WMS: <ServiceExceptionReport version="1.1.1"> <ServiceException code="InvalidSRS"> msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS must be valid for all requested layers. </ServiceException> </ServiceExceptionReport> URL it tries: http://209.98.160.119:8080/cgi-bin/mapserv?map=/var/www/map/map.map&layers=states&styles=&service=WMS&width=256&format=image%2Fpng&request=GetMap&height=256&srs=EPSG%3A900913&version=1.1.1&bbox=-20037508.34%2C-20037508.34%2C20037508.3384%2C20037508.3384 On Wed, Jan 6, 2010 at 2:56 PM, Ian Dees <[email protected]> wrote: > I tried this and am still not getting anything from my TIFFs.
