Sign-coverage explorer

A maintainer QA tool. This map plots every NYC street segment's parsed alternate-side-parking coverage, colored by how confidently each block matched a SODA sign record — so coverage gaps and low-confidence matches are visible and navigable. This is not the onboarding demo; it's for finding and inspecting the holes in the data.

Data as of

Confidence tiers

  • High — exact block match
  • Medium — approximate match
  • Low — fuzzy or fallback match
