Hi All,
I am trying to A) determine the mean aspect for a watershed and B) determine the mean aspect for the stream network in that watershed. I have tried both determining the aspect from the DEM/NHD and then clipping the raster to the watershed/stream and I have tried clipping the DEM/NHD first and then determining the aspect. When I attempt to clip a raster and then use the raster calculator, ArcMap entirely shuts down and a "Send Error Report" box pops up. This happens after I attempt to recalculate the new raster. Any ideas why this maybe happening and a solution around this? Many thanks in advance.
