FullDivide v1.0 · HydroSHEDS v2.0 30 m ====================================== Released 2026-09-23, tables rewritten 2026-09-30 Code FullHydro C code v10.01 (FlowDivide) What changed First release, North America and South America. Regions at three sizes: at most 2³¹, 2³⁰ and 2²⁹ pixels each (2³¹ is what a 32-bit integer can index). In the file names they are 160deg2, 80deg2 and 40deg2. 2026-09-30: every rectangle in the tables and vector attributes is left closed and right open: row_max, col_max (and their basin_, bbox_, window_ and cell_ twins) are one past the last pixel, so nrow = row_max - row_min. global_basin_id is -9999: a rank over two continents is not a global id; it will be given once every continent is computed. 2026-10-08: every table also as Parquet, every outline layer as GeoPackage and GeoParquet (.geo.parquet); nothing else changed. The basin tables are plain .csv now (they were .csv.gz): the same bytes, not compressed. Files are in one folder per continent: north-america/ and south-america/.
