| bsn_south-america_ge1km2.parquet | 8.1 MB | 2026-09-16 | simplified basin polygons, GeoParquet: one row per basin of at least 1 km² in id order, with the same rows and ids as the basin table (a basin too small to hold a cell keeps its row but has no geometry). Columns: the id, the area, the outlet, the map-view columns, and color_id (1–8, no two neighbours alike) so a map can colour the basins directly; the other columns are in the basin table |
