I have two surfaces loaded of the same area from different years. I would like to compare them to check for changes in elevation. Is there a way to create a file of the differences between these two surfaces?

    Actually we have added the ability to do exactly that in our latest v9.00 beta release. You can download the v9.00 trial from the main http://www.globalmapperforum.com and then load your terrain files, then use the File->Combine Terrains menu command to combine the terrain files with a subtraction operation to find the differences.

    Let me know if I can be of further assistance.

    Thanks,
