TL;DR: In this article, robust methods for the automatic determination of a digital terrain model (DTM) from point cloud data are presented, which operate on the original data points and allow the elimination of off-terrain points and the modelling of the terrain surface within one process.
Abstract: Different data sources for the determination of a digital terrain model (DTM) are available. New measurement techniques like laser scanning (LS) and interferometric synthetic aperture radar (InSAR) allow a high degree of automation and dense sensing. They pushed the development of new methods for data modelling. This paper presents robust methods for the automatic determination of a DTM from point cloud data. These robust methods operate on the original data points and allow the elimination of off-terrain points and the modelling of the terrain surface within one process. After a short description of the algorithms the paper focuses on the results of this technique applied to datasets from different sensors (airborne LS, terrestrial LS, satellite LS, tacheometry and photogrammetry). * Corresponding author.
