great video! I have a problem where I've classified a clipped raster (watershed) and now wish to generate some accuracy assessment points using the create accuracy assessment points tool. However, when I run the tool, it generates points in the NoData extent beyond the boundary of my watershed. Reclassifying or IsNulling the NoData values didn't help because all it does is create a new class in my classified raster and hence points are still generated throughout the rectangular extent of my study area. Any pointers would be much appreciated.

If I want to create a ROC curve, is it possible to only use the results from the confusion matrix? Can you please make a tutorial of making a ROC curve? I don't know what to do

Is this process only for LuLC classification?
