This paper describes the computational experience of generating the first 10m-resolution Height Above Nearest Drainage (HAND) raster data for the conterminous U.S. using the National Science Foundation (NSF) CyberGIS Facility based on the ROGER supercomputer. The HAND experiment is a joint effort with the NSF HydroShare project and the National Water Center for developing national-scale inundation mapping methodologies and data.
