Advanced Dtm Generation from Lidar Data
The introduction of laser scanning has triggered off a revolution in topographic terrain capturing, especially in the generation of digital terrain models (DTM). In this article refined methods for the restitution of airborne LIDAR data are presented which have been developed at the Institute of Photogrammetry and Remote Sensing (Institut für Photogrammetrie und Fernerkundung, I.P.F.) at Vienna...
متن کاملGeneration of Dem and Orthoimages from Spot Hrs Stereo Data without Using Gcp
The High Resolution Stereo (HRS) Scientific Assessment Program offered by the French space agency CNES and ISPRS, provided data sets from the SPOT stereo camera system (HRS) together with high precision ancillary data. Two test data sets from this program were evaluated: one is located in Germany, the other in Spain. The first goal was to derive orthoimages and digital surface models (DSM) from...

متن کاملState-of-the-Art: DTM Generation Using Airborne LIDAR Data
Digital terrain model (DTM) generation is the fundamental application of airborne Lidar data. In past decades, a large body of studies has been conducted to present and experiment a variety of DTM generation methods. Although great progress has been made, DTM generation, especially DTM generation in specific terrain situations, remains challenging. This research introduces the general principle...
متن کاملPrimary Data Analysis and Preparation for Dtm Generation
Experience in digital terrain modelling has shown, that analysis and preparation of the primary data is of great importance both for the productivity and the quality of DTM modelling. The paper presents a semi-automatic procedure to analyze the primary data in a numerical and graphical way. After gross error detection and data structuring using a triangular irregular network (TIN) the density a...
