Is there a way to clip a terrain in ArcMap, or make sure it doesn't exceed a certain geographical extent area in the first place?
After creating my terrain from a multipoint file it looks like this:
As you can see, the interpolation goes beyond the extent of the original las files (red boxes).
With a TIN it's possible to limit the extent either before or after you create it; before by adding a surface constraint to the las dataset and after with tools like Edit TIN and Delineate Tin Data Area. However, these options doesn't seem to be available when working with terrains.
