# US Parcel Layer — The Landrecords.us Nationwide Parcel Dataset

The [Landrecords.us](https://www.landrecords.us) National Parcel Dataset is a comprehensive,
standardized geospatial dataset aggregating **~157 million** parcel boundaries and their
associated land-ownership and taxation attributes, harmonized from thousands of local
jurisdictions across the United States into a single national schema.

Each record is a land parcel: a polygon representing the boundary of an individual tract of
land as delineated for tax-assessment purposes by the jurisdiction in which it resides, together
with ~94 standardized attributes describing that parcel. Geometries are derived from digitized
cadastral maps, surveys, recorded deeds, and legal descriptions.

This dataset redacts property ownership details.

## Dataset Creation

### Source Data

Parcel geometries and attributes are aggregated from **county and municipal tax-assessor
offices, planning departments, and GIS departments** across the United States. The raw source
data is ingested, harmonized to the common schema above, and validated. Locality-specific codes
(e.g., `zoningcode`, `usecode`) are mapped to standardized categories where possible and
otherwise retained in their original form.

### Precision & Processing

- **Source precision varies** with the original survey method vs. digitization from aerial
  imagery; there is no standardized way to ascertain per-county source accuracy.
- **Output geometry** is snapped to a `1e-7` uniform grid (~1 cm at most North American
  latitudes) and reprojected from source **NAD83** to **WGS 84** output; the datum
  transformation is typically accurate to within one meter but varies by latitude.
- Some structural attributes (`numunits`, `numfloors`) are **estimated** where direct source
  values are unavailable and confidence is high.

## Bias, Risks, and Limitations

- **Attribute completeness varies by jurisdiction.** Many `NULLABLE` fields are sparsely
  populated because thousands of independent authorities publish different attribute sets.
- **`lrid` identifies a parcel across space but not perfectly across time** — subdivisions and
  boundary changes can break lineage between quarterly versions.
- **Personal information:** ownership fields (`ownername`, `owner*` mailing address) originate
  from public records and may include the names/addresses of individuals. Handle in accordance
  with applicable privacy law and the non-commercial license terms.
- Standardized codes are best-effort mappings; verify against the originating jurisdiction for
  authoritative or legal use.
