I have been using ArcMap to construct a contour map using an ALOS PALSAR high resolution terrain corrected digital elevation model. The resulting contours initially look like this
I knew that there's a method to smoothen out the rugged/intersecting/un-interpretable contour lines which is applying Focal Statistics to the DEM. I was wondering which neighborhood method that is suitable to prepare the DEM for contouring
I found this tread that seems like it has an answer.
Here is another short video with a very simple way to do it.
