data sheet Features and benefits URCHN draws from Persistent Change Monitoring (PCM) data and OpenStreetMap (OSM) editing statistics to provide the most complete view of urban change available. ■ Maxar PCM data: This highly curated product identifies areas of persistent change within a time series of satellite images, tagging change polygons with the date of first detected persistent change. ■ OSM changeset data from OSMesa to track OSM edits in near-real time. ■ Maxar's Plus Metro basemap: This imagery basemap is updated annually to provide a current high resolution picture of thousands of major urban areas. ■ Maxar's Metro basemap project overview Preparing a mission (be it operational or foundational) requires up-to- date knowledge of features in the area of interest (AOI). In dynamic urban environments, the pace of change can exceed the pace of map creation. Maxar's change to Urban Change (URCHN) application can assist in answering the question of "where do I need to map next" to collect additional ground data and start answering the complex questions the GEOINT community face each day. Urban Change (URCHN) URBAN CHANGE (URCHN) info@maxar.com maxar.com Maxar has collaborated with Development Seed and Azavea to create a tool that combines multi- spectral change data, map currency statistics, and Maxar imagery to better understand the current state of urban development and how well its mapped. This capability will answer the question "where should I map" for those responsible for maintaining feature currency. Persistent Change Monitoring data coupled with OpenStreetMap editing statistics will highlight places that have changed and have not yet updated on the map. The URCHN dashboard above shows areas of detected change. The grid on the le displays aggregate change from spectral data, while the detail map to the right shows specific areas of multi-spectral change and mapping activity with supporting statistics.
