How it works

Part of GeoAI & Satellite Intelligence

  1. 1

    Set the baseline

    We fix a reference date and boundary, from satellite archive or a fresh drone flight.

  2. 2

    Capture each epoch

    New imagery is acquired on your schedule and aligned to the baseline.

  3. 3

    Detect and verify

    Models flag change. An analyst reviews each flag before it reaches your list.

  4. 4

    Alert and report

    Changes land in your dashboard with dates, areas and image pairs.

Who uses it

Works with

Put change detection to work on your site.

A KML, a sketch on a map or a district name is enough to start.
