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