How LandBinder works
LandBinder checks a user-defined boundary against available public datasets and organizes the results into a source-linked report. Returned facts, derived measurements, AI observations, and unavailable checks remain visibly separate.
Effective August 1, 2026
Four evidence classes
- Official
- A fact returned directly by an identified government source. Official does not mean current for every legal purpose.
- Derived
- A deterministic calculation from cited geometry or source data, such as geodesic acreage, overlap, proximity, or sampled terrain.
- AI observation
- An optional machine-generated imagery observation shown separately and never used to replace an official or derived result.
- Unknown
- A source was unavailable, unsupported, outside documented coverage, or returned no usable evidence. Unknown never means absent or safe.
Spatial basis
Each result states whether it uses the exact AOI polygon, a polygon intersection, an interior representative point, the centroid, deterministic samples, a nearby-radius search, or broader tract, county, watershed, or regional context. Generalized context is not presented as parcel-level evidence.
Provider isolation
Sources run independently with bounded requests and timeouts. One failed source does not fail the report. A report may therefore be useful and incomplete at the same time. Unavailable checks can be retried without replacing already returned facts.
Provenance and caching
Evidence records include source, source link, retrieval time, effective release where known, method version, spatial basis, and limitations. Completed analyses may be reused for 24 hours for the same account or anonymous browser session and exact geometry.
No composite score
The product does not create an overall land-risk or suitability score. Different users, projects, codes, financing requirements, and risk tolerances cannot be responsibly compressed into one universal number.
What still requires verification
Mapped screening cannot determine title, recorded easements, legal access, boundary location, local zoning interpretation, permits, utility capacity, water rights, environmental liability, subsurface conditions, or field conditions. Confirm those matters with the appropriate public office and qualified professional.
