Optimization of ASTER Elevation Data to Improve Watershed Delineation

The primary goal of this research is to examine the practical use of public domain satellite data in natural hazard modeling. Watershed delineation and characterization is one of the most important step in hydrological modeling. In last decade, considerable developments have been achieved for satell...
