What is Impact of Cell Resolution on DEM Depressions about?
1) The number and characteristics of depressions in a digital elevation model (DEM) depends on the resolution of the DEM. Higher resolution DEMs contain more but smaller depressions. 2) Depressions can be artificial, caused by errors in data collection and processing, or real features in the landscape. It is difficult to distinguish artificial from real depressions using only DEM data. 3) The presence of depressions prevents hydrological modeling of surface water flow. Depression removal techniques like
