Message	Is there a way to extract minimum/maximum elevation data for each square km from clipped DEM? I have created a polygon network covering desired area, but it is a large number of polygons considering the area of 12500 square kilometers, if it is necessary to use polygons can I do it in some automated way to obtain the raster containing minimum/maximum elevation data for each square km?
