Paste a written legal description and get a mapped parcel you can download as GeoJSON, KML, or a shapefile. Section and aliquot descriptions are resolved against BLM survey data; metes-and-bounds descriptions are computed as a traverse. Everything runs in your browser — nothing is uploaded and nothing is stored.
No AI is involved. The description is parsed with fixed grammar rules and the geometry is computed with survey math. The same text always produces the same polygon.
Section geometry comes from the BLM National PLSS CadNSDI survey grid (public REST service), queried directly from your browser.
Aliquot parts are approximate. Quarters and halves are produced by proportionally subdividing the section polygon. A real survey subdivides by measured corners, and sections are rarely perfect squares — closing sections on the north and west edges of a township are routinely short or long. Expect a good approximation, not a boundary survey.
Metes and bounds are computed exactly as written. Bearings are taken at face value. If the deed uses an assumed or grid basis of bearings, the figure will be rotated relative to true north until you correct it with the rotation field. The reported closure error is the honest misclosure of the calls as entered — a large value means a call was misread, omitted, or is wrong in the deed.
Not supported: lot-and-block subdivision descriptions (the geometry lives on the recorded plat, not in the text); government lots (irregular survey remnants); "less and except" clauses, which are not subtracted; and states with no PLSS survey — Texas, Kentucky, Tennessee, and the original colonies — where section references cannot be resolved, though metes and bounds still work if you supply a starting point.
This is a mapping aid, not a survey. Nothing here is a substitute for a licensed surveyor, and it should not be used to establish boundaries, resolve disputes, or record instruments.
