Hydrological models can beneยฎt from satellite-derived digital elevation models (DEMs) only after determining the hydrological model sensitivity to DEM inaccuracies. This study examined how vertical errors within a SPOT satellite-derived DEM of the 532 km 2 Little Washita River, OK, watershed aected

Digital elevation models (DEMs) are currently generated using satellite imagery, but little is known about how errors in satellite-derived DEMs aect hydrogeomorphological products such as relief, elevation contours, basin boundaries and stream networks. This study identiยฎed and minimized vertical er
