DEM filtering Algorithm


Recommended Posts

Hi,

I have a sample DEM that has been generalized and filtered but keeping the sharpness of features. I have tried all filters i know but i couldn't replicate it. I would like to see if someone knows how to do it.

Below are the links for the original and processed DEM:

Thanks in advance

Stuart
