Point-based and Area-based Deformation Analyses

Since several years, the areal acquisition of objects and their geometries - up to an integrated space continualization - got into focus of engineering geodesy. Consequently, objects are no longer sampled and discretized by a small number of individually defined signalized points. Instead, they are area-wise sampled by a large number of non-signalized points whose individual positions cannot be set up.




This fact makes completely new demands regarding the subsequent data processing: Up to now, deformation analyses are focused on analyzing single points or point differences to decide whether the sampled object is deformed at selected positions. Since there are no longer signalized points when using laser scanners and, thus, also no longer identical points between two epochs, judging an object to be deformed can only be based on an areal parameterization.
