Data

This project relies on open data shared by the City of Ottawa and OC Transpo. The methodology page explains how the OC Transpo GTFS data is processed using the supporting project repository.

You can download a copy of the data supporting this site. The data is available in both CSVs and Parquet format, depending on your preference.

The explorer tool itself uses a few additional GIS files from the City of Ottawa:

• Wards 2022–2026
• Ottawa Neighbourhood Study
• Road Centrelines (through doing this project, I learned how crucial roads are to making a map feel right)

Each of these files were downloaded as GeoJSON, modified using mapshaper (mildly simplifying geometry, removing unused data properties, and exporting at a lower level of lat/lon precision), then used in either GeoJSON or Shapefile format. The optimizations are (somewhat) tracked in issue #5, “Optimize geo datasets”.
