Hi Ron, Not sure, but then I'm not sure what form such an output would take.
There's the UniformRasterClassifier which would create bands of elevation (eg 0-100m, 100-200m, 200-300m etc). Hypsometric Tinting I think the term is. The other option is to convert the DEM from absolute values to angle of slope, and colour it accordingly. That would be a bit convoluted, but possible; it's also something that we're likely to provide for in the future with some form of raster neighbour calculator. But presumably for relief shading you'd need a defined light source, and only shape areas facing away from the light? I can't see a simple way to do that in FME, and I can't really see that being something we'd do in the future. Hope this helps - let us know if you've any more details about what form of output data you're looking for. Regards, Mark Ireland, Senior Product Specialist Safe Software Inc.
