A procedure to derive a digital elevation model (DEM) over a region spanning a few square kilometres by means of a ground-based interferometric synthetic aperture radar (GB-InSAR) is described. The results obtained at a test-site near the village of Sauze d'Oulx, Italy, are presented. The comparison with an existing DEM shows the good accuracy of the proposed DEM retrieval technique.
