I am writing a report about vertical changes for a ice-cored moraine, using multitemporal DTMs. The DTMs are made from stereomodels from aerial photos. I try to find som statistical tools that I can use for verify changes between the DTMs. I was thinking to use a significance test between the DTMs, but i don`t know how to use it. Did someone have any idea? Greatful for all help.
