Apologies if this is covered by the mailing list already. I have looked through
the documentation etc. and couldn’t find a clear explanation and have tried a
variety of srs settings to no avail. (BTW, how do you search the mailing lists
for multiple words?)
I have a map file with a mixture of vector and raster layers. For the vector
layers, my request url works fine with Lat/Lon ranges for the bounding box but
the raster layer requires the bounding box in eastings/northings ranges. I
would like one url that can query both layers with a latitude/longitude range
only. I think I’m missing something in explicitly declaring the overriding
projection scheme for the raster layer, is that correct? (The vector layers are
epsg:4326).
Thanks,
Andy
