I once wanted to generalize a high resolution raster and instead of MEAN i accidentally selected the default SUM technique, using a cell factor 5 (Lidar DEM is 1m resolution). When I used this result as input to the hillshade funciton what I got was what I can only describe a highly exaggerated hillshade. I deleted the results and recreated the generalized DEM but now I have the need to show more exaggerated terrain characteristics in a topographic map and it seems to produce the results I want albeit generalized. Is this a common way to do this or should I be using a different technique? How would I exaggerate a DEM without having to aggregate the raster?
