nycbuildxwalks 0.0.0.9001

  • Boundary layers labelled with a geographic CRS but holding coordinates outside longitude/latitude ranges are now treated as EPSG:2263 (NY State Plane, US feet), with a warning, before reprojection. The NYC Open Data Historic Districts GeoJSON (hd) currently has State Plane coordinates labelled as EPSG:4326, which previously produced near-global polygons and made build_crosswalks() fail with a GEOS topology error.

  • The Business Improvement Districts layer (bid) now takes feature names from f_all_bi_2. NYC Open Data changed the dataset’s schema, and the previous name column, f_all_bids, now holds numeric codes (0.0 for several districts), so distinct districts were merged when dissolving by name.

  • process_dataset() now warns when every value of a layer’s name column looks like a decimal number, a sign that the source schema has changed.

  • Invalid geometries in the combined boundaries are now repaired with GEOS in planar coordinates rather than with s2 on the sphere, matching the original Python tool. s2 repair could turn a polygon with reversed ring orientation into its complement.

nycbuildxwalks 0.0.0.9000

  • Initial package creation. Port of the Python NYC geography crosswalks tool by Nathan Storey at MODA-NYC.
  • Added nyc_datasets tibble with definitions for 15 NYC geographic boundary datasets.
  • Added download_all_boundaries() to download and combine boundary data from official NYC sources.
  • Added build_crosswalks() to generate long-form and wide-format crosswalk CSVs from boundary data.
  • Added make_run() to orchestrate the full pipeline.
