Change detection FAQ

How does the change detection workflow work?

Change detection compares two capture dates over the same coverage area and reports additions, removals, and modifications for mapped feature layers.

Which features can be monitored?

Buildings, vegetation, land-cover surfaces, pools, sheds, garages, fences, walls, and other visible site features can be tracked when the imagery supports them.

What outputs are delivered?

Deliverables include change polygons, before-and-after layers, added/removed/modified flags, and review-ready packages for GIS teams.

Who uses these outputs?

The workflow is built for systematic temporal monitoring, portfolio updates, municipal mapping refreshes, and operational review programs.
