    Independent demonstrations using open official imagery. These locations are not presented as Earth-Audit customers; monitored areas are approximate, not legal property boundaries.

    From location to evidence

    The property boundary comes first.

    Earth-Audit analyses only the land you define—not an arbitrary neighbourhood-sized square around a pin.

    A parcel map or a registry plan shows where the property ends. Bring that outline here and see what happened inside it since 1984.

    See how measurements work
    1. 01

      Choose the property

      Search an address, paste a Google Maps link or enter coordinates.

    2. 02

      Define its real boundary

      Upload a boundary file, draw the polygon or select a radius when no parcel file exists.

    3. 03

      Read the change history

      Review imagery, vegetation trajectory and pixel-level change inside that boundary only.

    4. 04

      Keep the evidence

      Use dated sources and a verifiable fingerprint when you need to share the record.

    A complete property record

    One record. Every relevant signal.

    Compare dated imagery, vegetation trends and risk context without piecing together separate tools or screenshots.

    No invented certainty.

    If a source has no coverage for your property, Earth-Audit says not available. Every available figure names its source, date and resolution. Evidence is not a legal opinion.
