Global River Network from Sentinel-2 (GRS)

Google Earth Application Description: GRS is a global, high-resolution (10 m) river network derived from Sentinel-2 imagery using optical-based water detection with DEM-based flow accumulation. Attributes: QA: River segment quality label from GRS, where "observed" indicates the segment was directly detected from Sentinel-2 imagery, "interpolated" indicates the segment was inferred using DEM fallback. geometry: River segment geometry from GRS. LEN_KM: Geodesic length of the river segment (in kilometers), calculated from the GRS geometry. HYRIV_ID: Nearest segment ID from HydroRIVERS dataset. NEXT_DOWN: HYRIV_ID of the downstream segment. NEXT_DOWN field in GRS dataset is corrected by ensuring that downstream segment IDs point only to valid segments within the dataset. If a NEXT_DOWN ID is missing, it traverses the HydroRIVERS network downstream until it finds an avaliable segment in GRS. ORD_STRA: Strahler stream order from HydroRIVERS. DIST_DN_KM: Distance (km) from the segment to the river outlet from HydroRIVERS (without modification).
