Abstract
This article reflects on the geodetic measurement techniques and processing methodologies that have been applied for subsidence monitoring in the Netherlands since the 1960s, driven by the legal obligation (according to the Dutch Mining law) for Nederlandse Aardolie Maatschappij (NAM) to monitor subsidence due to hydrocarbon extraction. Traditional geodetic techniques such as leveling have been supplemented with satellite based techniques such as GNSS (Global Navigation Satellite System, GPS) and InSAR (Interferometric Synthetic Aperture Radar, satellite radar interferometry). Processing methodologies, all with a solid foundation in the Delft adjustment and testing theory, have developed over the decades by and in collaboration with Delft University of Technology. All these developments undoubtedly carry the fingerprints of the scientific contributions of Prof. Teunissen. Precise and reliable estimation of deformation signals is more relevant than ever, with shallow subsidence issues induced by climate change and the millimetric computations required to determine relative sea level rise.
