GLObal river Width from Sentinel-2 (GLOW-S)

Introduction:

The GLOW-S dataset is a global river width dataset generated from Sentinel-2 imagery.                                                                                                                                                         

Dataset Features:

• Temporal Coverage: Data spans from 2017 to 2022.
• Spatial Resolution: Cross section level.

Postprocessing: When multiple observations for the same cross-section and date exist, the dataset averages these widths to enhance usability.

Column names for river width data:

• crossSxnID (cross section identifier): R<COMID>XS<Section ID>
• date (image capture date): YYYY-MM-DD
• width (river width captured in meters)

Column names for cross section shapefiles:

• crossSxnID (cross section identifier): R<COMID>XS<Section ID>
• lat (latitude in WGS84)
• lon (longitude in WGS84)

 Version updates:

19 Jun 2025: (1) The widths estimates below 10m have been removed.

                     (2) The cross-sections files and width data files have been mrged, so the user has to download only one file for                              each region
