Space-related services for building stock monitoring

The Building Stock Monitor Service aims at aiding municipalities with monitoring the entire building stock within their geographical borders. Presently, municipal map information and accompanying building polygon data are updated with a low frequency, depending on the budgets available. By using satellite data, the service is able to give the municipalities weekly updated data for their community which makes it possible for the municipalities to work more efficiently. The service’s target users are case officers, planners and operative staff of a municipality, whose daily operations consist of evaluating and following up on building permit applications (case officers), monitoring illicit building construction (operative staff) or perform urban or rural planning (planners). The service uses SAR data from Sentinel-1 and optical data from Sentinel 2 in order to perform change detection using machine learning and deep neural networks.
