Summary

This dataset contains the slope grid for the Asian continent from the Hydrologic Derivatives for Modeling and Analysis (HDMA) database. The slope data were developed and distributed by processing units. There are 19 processing units for Asia. The distribution files have the number of the processing unit appended to the end of the zip file name (e.g. as_slope_3_2.zip contains the slope data for unit 3-2). 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 [...]

Purpose

This dataset contains the slope grid for the Asian continent from 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.
