I've written a arcpy script that creates terrain datasets from LiDAR. After 18 hours it bombed.
Instead of starting the entire process over again, I want the script to pick up where is failed. How do I check, with arcpy/python, if a Terrain Dataset has pyramids? If it does, then how do I check if the Terrain Dataset has data sources already added to build the terrain? Basically, how do I access the Terrain Model Properties to check for... anything really... so that I can verify that they exist or not?
This is a fairly simple process for just about every other kind of feature using code like Exists or Describe, but I have been unable to find any documentation on how to do this with a Terrain Dataset.
