Which MERIT Hydro tiles do I need?

FullBasin is computed from MERIT Hydro, and MERIT Hydro is downloaded as 5°×5° tiles. Pick a region on the map and this page names the tiles that region was built from, so you fetch exactly those and nothing else. For that region this page names the FullBasin package to download and the MERIT Hydro source tiles you need, and gives its window on the global 90 m grid. The MERIT Hydro layers are not redistributed here; you obtain them from their own archive under their terms. The dataset is cut into 96 regions. A region groups whole basins — a region is a unit for processing and downloading, not an arbitrary square of raster.

What to download for this region
Pick a region on the map, or choose one from the list above.
The tiles listed below are not ours to give. They are MERIT Hydro (Yamazaki et al., 2019); register on the MERIT Hydro site and download them there. This panel only tells you which of their files this region needs.

This site runs on a basic hosting plan with a fixed number of requests a day. If a map stops loading, it is most likely that a lot of people are using it at once — try again in a few minutes. We will raise the budget as the traffic grows. The archived files on Zenodo are never affected.
