Sorry to ressurect an old topic, but I see that the ability to reproject raster layers has been added. That's great news for me! However, I can't seem to get her working... I've just downloaded, intalled, and referenced to version 6, but appears that GeoTiffRasterLayer.ImageSource doesn't have a "Projection" property available (from the sample code here wiki.thinkgeo.com/wiki/Source_Code_ServicesEditionSample_GeoRasterProjection_CS_120720.zip). I could be missing something, but have you got any hints on what I am doing wrong? Thanks for the help again!
