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.

Public-domain data, kept current for you.
Every layer below is public-domain federal data. We keep our own current copy of each one and refresh it on a regular schedule, so the maps and tables you see are always tied to the official record. Each dataset has its own landing page with coverage, refresh cadence, and the Bield features it drives.
Terrain & elevation
Ground-truth land shape — slope, aspect, contours, hillshade — sourced from federal LiDAR programs.
- Detailed
USGS
USGS 3DEP LiDAR-derived terrain
Bare-earth elevation that sees through the canopy.
The USGS 3D Elevation Program publishes airborne LiDAR scans of the United States, processed to bare-earth elevation, canopy height, and derived layers at 10m and finer resolutions. It is the foundation of Bield: Hunt's terrain stack.
Open USGS
USGS topographic contours
Tri-resolution contour lines, rendered from 3DEP elevation.
Vector contour lines derived from USGS 3DEP elevation at 100ft, 40ft, and 20ft intervals. Rendered server-side so contours stay sharp at every zoom without round-tripping to a vendor.
OpenUSGS
USGS rendered hillshade
Photorealistic terrain shading.
Multi-direction hillshade tiles generated from USGS 3DEP. Three azimuths blended (315°, 270°, 45°) so terrain reads naturalistic without the harsh single-light look of stock renders.
Open
Hydrography & marine

USGS / NHDPlus
NHD — National Hydrography Dataset
Every river, stream, and waterbody, classified.

OpenUSGS Water Services
USGS river gauges (live)
Live flow, stage, and temperature from every USGS station.
Real-time and historical USGS gauge data, synced hourly to Bield's backend so river pages always show current conditions without an external API round-trip on every page view.

USGS Gap Analysis Project
PAD-US public lands
Every public-land polygon in the United States.

OpenCounty GIS offices (aggregated)
County parcels
Private parcel boundaries from county GIS.
County-level parcel polygons aggregated from public GIS offices. Coverage hits ~80% of US counties; the remaining 20% are honest gaps with no fake polygons drawn.

NOAA NCDC
NOAA climate normals (1991–2020)
30-year frost-date probability and growing-degree-day baselines.
The NOAA 1991–2020 US Climate Normals — 30-year averages for temperature, precipitation, and derived agricultural indicators. The statistical backbone of Bield: Farm's frost-date probabilities and growing-degree-day modeling.

OpenApple WeatherKit
WeatherKit (per-trip auto-capture)
Conditions auto-stamped on every Hunt sit, Fish trip, Farm log entry.
Apple WeatherKit returns hyper-local conditions for any lat/long. Bield queries it at the moment a hunt, trip, or log entry is created so the conditions get stamped automatically — no manual entry, no rounding, no guessing later.
