Proposal: make use of OSM vector data rather than bitmap analysis #7

Closed kekscom closed 7 years ago

Drawback of vector might be rasterization effort. OTOH yoi get much clearer information about feature types. There are already nice data services like https://mapzen.com/projects/vector-tiles/

I could also provide you with pre-rasterad data via http://osmbuildings.org/

The system I've used could easily be changed to use alternate tiles. The ideal tiles would have no line-borders on polygons, no text and no anti-aliasing.

To try it out with alternate map tiles, edit the tile URL in generate-world and colour. You can then pick lat/long locations from the tiles to see what the colour is, and update a copy of the colours config file for that tileset.

I use http://lemur.ecs.soton.ac.uk/~cjg/clickymap/ to get the lat/long for the thing I'm interested in and then ./colour --ll --point 50.93659,-1.39536

I've seen it. Alternate map tiles would also mean redefinition of colors. Not to mention anti alias etc. However, I like the idea for simplicity.

Meanwhile I have proper X/Y/Z rasterization for buildings in place. Just need to connect to geocraft via synchronous coordinates. Plus removal of the current building detection.

I'll show you a demo asap.

For coordinate picking, I can recommend http://osm.org ("Export"). But still I didn't manage to configure with --ll See #6
