# TODO - Map quality
|
|
|
|
## Boundary clipping
|
|
|
|
- roads
|
|
- what if they start/end in bounds, but briefly dip out? arboretum place east
|
|
|
|
- intersections
|
|
- some intersections partly cross border, is that actually fine?
|
|
|
|
- areas
|
|
- move the code to do this to clip. can probably get rid of find_blah_btwn for lonlat, right?
|
|
- some areas in small_seattle are borked or missing
|
|
- at least for lakeslice, we have points in good orders, but need to clip areas too.
|
|
|
|
- use real map background by default
|
|
|
|
## 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?
|
|
|
|
## More data
|
|
|
|
- lanes: https://data-seattlecitygis.opendata.arcgis.com/datasets/49d417979fec452981a068ca078e7070_3
|
|
- not filled out for most streets
|
|
- traffic circles: https://data-seattlecitygis.opendata.arcgis.com/datasets/717b10434d4945658355eba78b66971a_6
|
|
- https://data-seattlecitygis.opendata.arcgis.com/datasets/sidewalks
|
|
- disagrees with OSM road centers sometimes
|
|
- https://data-seattlecitygis.opendata.arcgis.com/datasets/curb-ramps
|
|
- high quality thick roads: https://seattlecitygis.maps.arcgis.com/apps/webappviewer/index.html?id=86cb6824307c4d63b8e180ebcff58ce2
|
|
- 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?
|
|
- experiment with https://docs.rs/clipping/0.1.1/clipping/gh/struct.CPolygon.html and https://github.com/21re/rust-geo-booleanop
|

## 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
