I am a student and I have to work out a project about soil loss on a plot. I need basic measurements of this plot such as length, width, area and slope for my erosion calculations.
I have got my hands on a 4 GB large DHM measured by LIDAR in a TIFF file format.
My question is now, how do I preform these calculations on this file format? I guess I need to convert it so I can use it in IDRISI or ArcMap?
