After successful completion of the course, students are able to calculate digital surface and terrain models as well as orthophotos based on data from laser scanning and stereo photogrammetry and to analyze and visualize them. Students have knowledge of the basic techniques for capturing topographic and hydrographic data and are able to apply different interpolation methods depending on the data situation. They are able to program simple interpolation approaches themselves and they are able to analyze and visualize topographic models and to assess their quality. The students know how to access and useuse nationally and globally available data sets and to apply them as a basis for individual questions in environmental engineering.
