Gregory's ServerThat's pretty neat, but the cool thing is that the low zoom support means you can zoom out and see a pretty good overview. This really makes Firefox work hard (it's deciding on colors for 100k's of features), but it works. https://iandees.github.io/TIGERMap/docs/WorldMap/?filter=%28color%29%2540user#map=6.45/44.986/-93.331

 One interesting thing that's hard to see with Matt's tool is that the tiles all have information about any large polygons they sit in. For example, you could use this to build a reverse geocoder by mapping the point you're looking for to a tile, fetching the tile, and looking at what polygons your point sits in. Neat! Another thing I'm thinking about: what if we pass the filtering logic to @bdon@mastodon.sociall's pmtiles Cloudflare Worker code and have it do server-side filtering so the tiles aren't as big on the wire. 🤔 |
The tiles are pretty big (tiles in Manhattan are 2-15MB), but they compress well (900KB-5MB). The output pmtiles file is 530GB. I built the profile here if you're interested in how it works: https://github.com/onthegomap/planetiler/compare/main...iandees:planetiler:lowzoom-qa-tiles
