Digital terrain models and geomorphometry  

The aim of the study course is to give students an insight into digital terrain models and their application. The tasks of the study course are: to provide knowledge about different types of digital terrain models; to promote understanding of impact of methods of storage and creation of these models on their quality and potential usage; to introduce popular open access and paid models; explain the sources of errors in digital terrain models and the adaptation of the models to various popular practical applications; to provide skills in the preparation of digital terrain models and acquisition of geomorphometric indicators based on them; to provide practical insight into the possibilities of using models in conducting applied research of physical and human geography. Language of course teaching: English, Latvian. Results Knowledge: 1. is familiar with different types of digital terrain models and their acquisition methods; 2. characterizes the impact of acquisition methods on quality; 3. explains the principles of error propagation in the process of development and application of digital terrain models; 4. characterizes geomorphometric measures and their potential use; 5. explains the possibilities of digital terrain model usage in the study of processes of different scales. Skills: 6. prepares digital terrain models; 7. prepares visualizations of digital terrain models; 8. critically analyzes the accuracy and errors of digital terrain models; 9. adapts models for selected application; 10. performs extraction of the geomorphometry characteristics of the terrain; 11. analyzes the directions and properties of water flow; 12. analyzes the visibility of the terrain. Competences 13. reasonably selects the digital terrain model acquisition methodology and storage method appropriate for the intended use; 14. assesses the impact of errors and uncertainties in the data and their analysis on the results obtained; 15. makes suggestions for improving data processing processeses in order to draw higher quality conclusions.
