An interactive web map of the New Zealand Transport Agency's Crash Analysis System (CAS) data, representing all accidents that have been attended by police, given a location, and that we have chosen to present (based on currency).
Made with Python (to read the raw CSVs and produce a nice GeoJSON with useful filters and attributes to build the popups) and Leaflet (to display the GeoJSON on the map).
- Chris Hewitt (NZTA), for early feedback and a "go ahead"
- Tom Pettit (Wellington City Council; New Zealand Centre for Sustainable Cities) for support and feedback
- The NZTA, for publishing this data in a largely machine-readable format
