Hydro1k

HYDRO1k is a geographic database developed to provide comprehensive and consistent global coverage of topographically derived data sets, including streams, drainage basins and ancillary layers derived from the USGS' 30 arc- second digital elevation model of the world (GTOPO30). HYDRO1k provides a suite of. HYDRO1k Documentation ReadMe. HYDRO1k Documentation. Table of Contents Introduction Data Layers Data Set Development HYDRO1k, developed at the U.S. Geological Survey's (USGS) EROS Data Center, is a geographic database providing comprehensive and consistent global coverage of topographically derived data sets. Developed from the USGS' recently released 30 arc-second digital elevation model (DEM) of the world ( GTOPO30).

9 Dec Abstract: HYDRO1k is a geographic database developed to provide comprehensive and consistent global coverage of topographically derived data sets, including streams, drainage basins and ancillary layers derived from the USGS' 30 arc-second digital elevation model of the world (GTOPO30). 5 May The database used in the development effort was the HYDRO1k product (http:// #/Find_Data/Products_and_Data_Available/HYDRO1K) with a native spatial resolution of 1 km, the highest resolution database of global coverage of standard elevation-based derivatives (slope, aspect, elevation. The database used in the development effort was the HYDRO1k product (http:// #/Find_Data/Products_and_Data_Available/HYDRO1K) with a native spatial resolution of 1 km, a high resolution database of global coverage of standard elevation-based derivatives (slope, aspect, elevation, compound.

5 Aug Currently, there are three authoritative sources of global hydro data out there, all available free to the public for non-commercial use: HydroSHEDS, HYDRO1K, and the GRDC's Major River Basins of the World. The HydroSHEDS dataset was derived from SRTM elevation data, while the HYDRO1K and. Index of /dist/Hydro1k. [ICO], Name · Last modified · Size · Description. [ PARENTDIR], Parent Directory, -.
