intersections that would be connected by a road that starts or ends OOB. result looks great!

TODO - Map quality
Boundary clipping
- lakes missing from small_seattle
- some border intersections have weird OOBish geometry, or the arrows look weird
- simplify border node detection, only do it in convert_osm?
Geometry
-
bad polyline shifting remains
- from the remaining cases, looks like we need to totally remove some tight points and retry
- make polygons use the corrections too?
- bad polyline shifting causes jagged lane endings in generalized_trim_back
-
handle small roads again somehow?
- reduce degenerate min trim. the disabled fix doesn't look great.
- I40, I25, I0 cut corners when merged. disabled fix works, but breaks other things.
- try it bigger
- deal with loop roads?
- model U-turns
-
degenerate-2's should only have one crosswalk
- then make them thinner
-
car turns often clip sidewalk corners now
-
figure out what to do about yellow center lines
- intersections on one-ways look weird
- yellow and white lines intersect cars and turn icons and such
- who should own drawing them?

- OSM has footways
- but theyre not marked everywhere
- and theyre hard to associate with roads (sometimes need to infer a planter strip)
- draw benches, bike racks
- render trees
- look for current stop sign priorities

Low-priority geometry issues
-
if building front path intersects another building, then scrap that building.
- or wait, just require bldgs to be even closer to sidewalk first.
- need to do polygon vs polygon check!
- will need to speed it up with quadtree containing entire buildings. make sure these are easy to use.
-
can we make OSM buildings with holes?
More problems to fix
- Disconnected map
- now that LCing model is simple...
- Impossible turns (from a far bus lane to a crazy left)
- Buildings intersecting roads, probably because bad lane inference
- when this happens, get rid of parking lanes first (one or both sides?)
- iterative process... have to redo affected roads and intersections
- we havent filtered buildings by proximity to sidewalk yet
- if we dont filter at all, we pick up some houseboats! :) should draw water...
- undo disabled traffic signal assertion
Release
- publish the map data
