Geos.722 Digital Terrain Modeling (3 C.H)
Course Objectives
The proposed course is aimed to aware the students with the importance and applications of the digital terrain modeling. The students will learn the concept and will be trained using computer- based exercises to develop their capacity of deriving topographic information from the remote sensing based digital elevation models.
Course Contents
- Introduction to Digital Elevation Model (DEM), Digital Terrain Model (DTM), Digital Surface Model (DSM) and Triangulated Irregular Network (TIN)
- Downloading and processing remote sensing based DEMs; Computation of primary topographic attributes: terrain slope, aspect, hill shade and view shade
- Application of DEM for drainage network mapping and watersheds demarcation.
Practical: Computer exercises to develop DEMs, analyze them and derive topographic basic attributes.
