23. Digital Watershed Hydrologic Observation Data Geospatial Data (GIS) (Relational database) Digital Watershed Remote Sensing Data Weather and Climate Data (EOS-HDF) (NetCDF) A digital watershed is a synthesis of hydrologic observation data, geospatial data, remote sensing data and weather and climate data into a connected database for a hydrologic region
