This tool can be used to remove pits from a digital elevation model (DEM). Pits are single grid cells with no downslope neighbours. They are important because they impede overland flow-paths. This tool will remove any pits in the input DEM that can be resolved by raising the elevation of the pit such that flow will continue past the pit cell to one of the downslope neighbours. Notice that this tool can be a useful pre-processing technique before running one of the more robust depression breaching (breach_depressions_least_cost) or filling (fill_depressions) techniques, which are designed to remove larger depression features.
