I've been given a raster of degree slope which I need to convert to percent slope. As the original DEM is not available and those who provided the raster want me to work with this one, I have to convert the degrees to percent. I've attempted to do this with raster calculator, in ArcMap, with the formula (Tan("Degrees"))*100 but this returns nonsensical values with 9+ digits and positive and negative values.
I imagine this is simple but I am doing something incorrectly. Am I missing something or is the wrong syntax? How do I properly convert a degree slope raster to percent slope raster?
