Vector tiles

TODO

Maybe integrate into this page:

• User:Bk#Vector-Tiling
• Tile data server
• WikiMiniAtlas/Vector tiles - Documentation for the Vector tile system currently in use by the WikiMiniAtlas, Wikimedia page
• further work on links below; verify links and descriptions; discuss structure; integrate with Tile data server --Ikonor (talk)
