I need to generate random points using a raster layer, which is classified into 5 classes of TPI (terrain position index). This should be a stratified random sampling design, with an equal amount of points on each class and ideally a minimum distance between the points.
I prefer to work in ArcMap. Does a tool for this exist? I heard Hawths tools could work, but I have v.10.3 so maybe not.
You can see one of the sites (classified TPI) here:
