1. What LANDOS is

The land signal engine. It turns county parcel records into scored, ranked opportunity leads, with a receipt for every lead.

How the score works in this demo

Each detected signal adds fixed points. The score is the sum of detected signal points, on a 0 to 100 scale. Category caps: Tax 25, Ownership 25, Land 25, Market 20, Condition 5. Bands: 70 and above is Priority, 50 to 69 is Qualified, below 50 is Watch. The scoring math is deterministic: the same signals always give the same score.

SignalCategoryPoints

The 12 named signals are a subset of the documented 50-signal model. Weights in this demo are illustrative and fixed for demonstration. They are not the production weights.

2. The synthetic dataset

Three invented parcels in a fictional county. No real owner names, no real addresses, no real parcel IDs.

ParcelLotAcresZoningAssessed value (synthetic)Owner

SYN-002 SyntheticCreek Lot1.1R-1$12,000Withheld in demo
SYN-003 SyntheticOld Grove Tract9.6AG$41,000Withheld in demo

Do not treat these as real parcels. Demo County does not exist. Lot names are invented. Assessed values are invented. Owner information is withheld by design; no owner PII appears anywhere in this demo.

3. The walkthrough

Run the full pipeline at once, or step through it one stage at a time. Five stages: ingest, signal detection, scoring, ranking, provenance receipts.

Stage 0 of 5: idle

    4. Provenance receipts

    Select a parcel to inspect its receipt. Copy the receipt, or copy the full run as one JSON document.

    Selected parcel: SYN-003 (highest score)

    
      

    Nothing copied yet.

    The receipt hash is a real SHA-256 of the canonical receipt text, computed in your browser. You can verify it: take the canonical text shown in the receipt under hash_input, hash it with any SHA-256 tool, and compare it to sha256.

    5. What you would get as a buyer

    In the live system, not in this demo. This section describes the deliverable, so you can judge it against the demo above.
