All 106 entries of sites.json in one table. Click a column head to sort; type in the box to filter; a kind, a country or a map can be picked from the lists. Every site name opens our page about it; the licence cell opens the site's own terms page where we found one. "Data and models" is what the site itself says, where we read it. Back to the ranking and the ten ideas.
