I would tend to utilize ArcGIS to perform surface difference between two TIN's or Terrains but my recent attempts have been too costly computationally. Instead, what I would like to accomplish is to perform a surface difference between two raw XYZ files and produce an output XYZ file. Is there a mathematical equation (via Python code) that I can use to generate this desired output? Obviously it would be focused on the difference in elevation (Z) of one file versus the other.
Once i have the new XYZ file, i would just proceed to create a TIN or Terrain of this XYZ file.
