Summary

This contains the North American portion of the Hydrologic Derivatives for Modeling and Analysis (HDMA) database. The HDMA database provides comprehensive and consistent global coverage of raster and vector topographically derived layers, including raster layers of digital elevation model (DEM) data, flow direction, flow accumulation, slope, and compound topographic index (CTI); and vector layers of streams and catchment boundaries. The coverage of the data is global (-180º, 180º, -90º, 90º) with the underlying DEM being a hybrid of three datasets: HydroSHEDS (Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales), Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010) and the Shuttle Radar Topography [...]

Purpose

This contains the North American portion of the Hydrologic Derivatives for Modeling and Analysis (HDMA) database. This dataset is appropriate for use in continental-scale modeling effort. The Pfafstetter codes provide topological information that can be useful for upstream and downstream tracing.
