I have a DEM, resampled at 100 x 100 and clip by mask with a polygon.
Unique values report give me Total pixel count: 733810 with NODATA pixel count: 427098.
Aspect and Slope map give me the same number of pixels but NODATA pixel count: 423251.
My question is why when i clip by extent or clip by mask , area around my raster has NODATA values? How can i get rid of these so have same amount of pixels to every parameter? The problem doesnt solves if i reclassify them with zero because i need to export them to csv and analyze them and need exactly same number of pixels.
