I love this one screenshot from when I first got nice rendering implemented, showing all sorts of detailed rivers. I’ve backed way off that because it’s so much data, etc. But in filtering so much I’ve lost something.
Mike Bostock did a pure-D3 vector tile renderer, so I bashed up a river renderer. And it’s fast. So I made some screenshots where I don’t filter the data on Strahler number at all; all rivers, all the time!
The server generation time is acceptable once you rely on caching. Data sizes are pretty bad though, 27 megs a tile :-P
