Assessment of the Quality of Digital Terrain Models

It is the objective of this course to get acquainted with methods which check and improve Digital Terrain Models using manual and automatic procedures. Results with these methods and test material of EuroSDR and other projects, comprising DTMs derived from laser scanning and digital photogrammetry, are presented. The applied methods use standard and robust statistical concepts. Photogrammetry and correlation techniques are applied in the automated procedures. The different standards in Europe regarding the assessment of the DTM quality are compared.
