Sidewalk Widths Toronto

Sidewalk Widths Toronto uses the City of Toronto's open sidewalk dataset to produce a map of sidewalk widths for the city.

This is inspired by, and forked from, Meli Harvey's Sidewalk Widths NYC project. We borrow methods and code from the original project.

This repo contains the notebooks to reproduce this work, as well as the finished Sidewalk Width dataset in GeoJSON format.

Methodology

  1. Polygons from City of Toronto's open data portal: Sidewalk Polygon

  2. Dissolved touching sidewalk polygons (this example doesn't show a difference) Dissolved Polygon

  3. Find sidewalk centerlines Centerlines

  4. Remove short ends and simplify Centerlines Simplified

  5. Measure distance from centerlines to original polygon Centerlines Widths
