My apologies if I have posted this in the wrong area.
I am looking for a way to selected micro-topographic features. Pretty much I want to extract all knolls, eskers, hummocks etc that are evident on the lidar into their own raster. Does anyone have any idea or any programs that can do this.

Many thanks
