The data. And the data underneath the data.
Two catalogs. Bield's per-vertical data products live in Hunt, Fish, and Farm — rut dates, frost dates, hatch calendars, SST thresholds, livestock breeds, regulations. Each one is built on top of the federal data stack below: USGS, NOAA, USDA, NHD, and the rest. Both layers are surfaced here.

The federal data stack underneath
We don't resell data. We self-host it.
Every layer below is public-domain federal data, processed on our own infrastructure (Hetzner + Cloudflare R2) and rendered without a tile-vendor middle layer. Each dataset has its own landing page with coverage, refresh cadence, and the Bield features it drives.
