Australian Racing Open Data
Open, machine-readable datasets for Australian racing — the kind of data that
normally sits behind a login, a paywall, or nowhere at all.
Two of these datasets, as far as we can tell, have never existed publicly
before: track geometry (turn radii, cambers, straight lengths, first-split
distances — gathered by writing to 111 racing clubs and state bodies) and
greyhound GPS sectionals at 50-metre resolution.
Everything here is rebuilt and pushed every… See the full description on the dataset page: https://huggingface.co/datasets/brucem1967/au-racing-open-data.NYC-Airbnb-Open-Datawhatsapp-open-data
