Persistent Change Monitoring

Identify and monitor relevant change at scale

Discover change

Changes in infrastructure and land use are frequent and widespread, making it challenging for analysts to locate, map and monitor change over broad areas of interest. Persistent Change Monitoring (PCM™) highlights human changes in an area and displays persistent change accessibly as a color-coded geospatial data layer.

Filter out noise

Traditional two-date change detection often presents false positives, attributable to factors like sun angle and harvested farmland. PCM™ uses extensive sampling to see past cyclical change and shine a light on the most important changes in an area.
