Maxar’s patented Persistent Change Monitoring (PCM) information layer with premium subscriptions will now also be included in SecureWatch. SecureWatch is Maxar’s cloud-based subscription service for on-demand access to satellite imagery and Earth Intelligence.
PCM is an image-based change detection capability that utilizes scale and sensor independent algorithms to feature areas of human activity and other change. Any change which becomes permanent after being made to Earth’s surface is “persistent change”.
For example, new building construction will be persistent change, while vegetation varying with the seasons will not.
The capability to visualize PCM is now also available to SecureWatch Premium subscribers and is made available via the web application or through the SecureWatch Web Map Services (WMS). Additionally, Maxar offers PCM as a stand-alone, offline product too accompanied with robust metadata and complete attribution unlocking the ability to perform more in-depth analysis.
