alt Hacker NewsIt's blowing mind a bit that you made this and released it because I was on the verge of doing it myself. Very nice work.
Really curious about your data sources. Where are you getting all this stuff?

Thanks, that's really nice to hear. Happy to share:
- Listings: RentCast's API (licensed), pulled weekly.
- Parcel boundaries: state and county GIS services where they publish statewide parcels (about 20 states), and Realie (licensed) for the rest.
- Public land: USGS PAD-US 4.1, filtered to fee-owned, open-access land of 50+ acres.
- Elevation: USGS 3DEP point queries. Roads: Census TIGER. Flood: FEMA's National Flood Hazard Layer. Wildfire: Forest Service Wildfire Hazard Potential (2023). ZIP search: Census ZCTA centroids.
The free state parcel services were the biggest hunt: every state publishes differently, and a couple that looked open turned out to be test or internal-use-only endpoints.
