Claim plotting

Claim plotting turns paper — location notices, certificates, survey descriptions — into claim polygons plotted on your interactive map.

How it works

Upload the documents for a claim block into a Petra chat and say you want them plotted. Petra reads the paper (with vision — old scans and handwritten notices included), frames the map on the ground the notice names, and works out the geometry: bearings and distances, tie points to known corners, and the metes-and-bounds arithmetic that turns "N 45° E, 600 feet" into a polygon on the ground.

When the notice ties to a landmark no record can resolve — an old shaft, a named boulder, a survey monument — Petra tells you what the monument is (in the notice's own words), roughly where to look, and how rough that estimate is, then asks you to click the spot on the live map. Your click establishes the point; a block that names several monuments collects them one ask at a time, and every claim gets its own.

The result lands as plotted claims on your map with an honest per-claim confidence tier, alongside the land holdings you imported directly. Plotted claims keep their link back to the source paperwork, so you can always answer "why is this corner here?"

Availability

Claim plotting is being rolled out gradually. If it's enabled for your account, just ask Petra — "can you plot claims from a location notice?" — and upload the paper in chat. If it isn't enabled yet and you need it, get in touch — we're onboarding projects steadily. This topic will grow a live walkthrough when the rollout completes.
