Sandra K. Poppenga, Bruce Worstell, Jason M. Stoker, Susan Greenlee
2010, Conference Paper, Remote sensing and hydrology
The methods to extract surface flow from coarse elevation data are well documented; however, the methods to extract surface flow from high-resolution, high-vertical accuracy digital elevation models (DEMs) derived from light detection and ranging (lidar) are less documented, but yet more complex. As lidar data are increasingly used to generate...
