Why this directory matters
These pages are designed to work as dataset landing pages first, download guides second, and interactive previews only where that adds value. Search engines and AI answer engines can read the summaries, steps, FAQs, and structured data directly from the HTML.
The directory clusters related sources so DEM, boundaries, OSM, transport, land cover, imagery, hydrology, and infrastructure data are easy to compare and cross-reference from one canonical hub.
