Omschrijving
One of the tasks of Rijkswaterstaat is to carefully map the surface height of the Netherlands. Normaal Amsterdams Peil (NAP) is the reference level for heights in the Netherlands. It consists of a network of leveling benchmarks, that have been measured for more than 200 years by traditional leveling. Recent developments in geodesy contain the upswing of Interferometric Synthetic Aperture Radar (InSAR) to measure surface deformation. Through the InSAR technique dozens of SAR images are stacked and amplitude and phase information is used to detect, either permanent or distributed, scatterers and estimate surface displacements up to mm-accuracy, respectively. Rijkswaterstaat has a growing interest for nationwide deformation maps.
