Description
This tool saves grid cell values to point (grid nodes) or polygon (grid cells) shapes. Optionally only points can be saved, which are contained by polygons of the specified polygons layer. In addition, it is possible to exclude all cells that are coded NoData in the first grid of the grid list.
