Dr. Cornelis Stal is a post-doctoral researcher with experience in the field of the combination, processing and quality analysis of airborne and terrestrial laser scanning for 3D city modeling. His special interest is in the (automatic) generation of geometric, radiometric and semantic rich 3D models, derived from irregular point sets and other spatial data sets. This means that both laser scanning as a discipline in the land survey and geo-IT (GI-systems, GI-programming, GI-management, ...) are important pillars of his research. Recent research opportunities have allowed him to add an additional focus on geomatics applications for bathymetric modelling. He is currently working on the analysis and processing of GNSS data acquired from tidal buoys.
