Our first MapRoulette challenge is online--check it out!
Coordination for the NYC bike lane cleanup and update. We plan on creating MapRoulette challenges to update OSM's bike lane data using the latest data available from the city.
The simplest way to get going is to clone this repository, cd
into it and run:
make
This will download all the relevant data and process it, then create challenge data.
The data is in two shapefiles: data/nyclines.shp
and data/osmlines.shp
. The
data was created using the Makefile
.
The Makefile
contains recipes for downloading an OSM extract for NYC.
It clips to NYC borders (not just the bounding box) and attempts to select just
the features that are bicycle-related. Run the following to get OSM data:
make boroughs osm_bikelanes
You'll need osmtogeojson to run the above recipe, you can install it with npm:
npm install -g osmtogeojson
The city's latest bike lane data is in data/cscl_bike_routes/original
. This
data is not available online, otherwise we would download it from there. We have
reprojected and simplified it, and you can do the same with:
make nyc_bikelanes
