Settlement monitoring using space-borne radar interferometry, in the context of large infrastructure projects

Geodetic data acquisition in urban areas and along linear infrastructure are major cost drivers in big infrastructure projects. Modern remote sensing methods help us to manage data acquisitions with high effectiveness during the different phases of such projects. Here, we show how we apply space-borne radar interferometry to monitor settlements. We showcase two examples: a) the new E18-highway development project in Bærum, Norway; and b) the Follo Line railway project between Ski and Oslo. Monitoring is done by exploiting very high resolution TerraSAR-X data (ca. 1.5 x 1.5 m spatial ground resolution) in the E18 case, and high resolution Radarsat-2 data (ca. 7 x 7 m spatial ground resolution) in the Follo Line case. In both cases,
