Script for downloading New York City building footprints and converting them to OpenStreetMap format.
nyc_osm_blockmaker.py block [nyc_geoservice_api_key]
block should be a 6-digit code that specifies a city block -- 1 digit for the borough (1=Manhattan, 2=Bronx, 3=Brooklyn, 4=Queens, 5=Staten Island) and 5 for the block number within that borough. Additional digits can be appended to request a partial block, up to a full 9-digit BBL (borough-block-lot) code.
All building footprints that match the requested block will be converted to OpenStreetMap features and saved in a single .osm file. Building ways and multipolygons will be tagged with building=yes, height, and nycdoitt:bin, as in the original NYC building import. (See https://github.com/osmlab/nycbuildings.)
Optionally specify a nyc_geoservice_api_key to add addresses from NYC's Geoservice API to the footprint features. (See https://geoservice.planning.nyc.gov/Register to request a Geoservice API key.) Buildings with only a single address will be tagged with addr:housenumber, addr:street, and addr:postcode. Buildings with multiple possible addresses will remain untagged -- address data for these is best determined by survey.
