hi everyone, i am dealing with DEM data for a river basin area. The question is after some execution, each pixel (e.g. pixel A) will be assigned a value which represents the number of pixels above the location of pixel A. But i found the highest value in the content layers are much smaller than those in the map window. (showed in figure 1) Could anyone tell me whats going on? Thanks a lot! By the way, i dont know what is that streched value mean, but it all showed 255.
