The proposed course provides basic understanding about digital elevation models (DEMs) and their applications in Civil Engineering and Earth Sciences. Further, in the proposed course various DEMs, their source, generation techniques, derivatives, errors and limitations would be discussed extensively. Surface Hydrologic Modelling using DEMs, modelling derivatives and their applications would also be discussed.

Intended audience: Under and post-graduate engineering and post graduate science students/Faculty

Prerequisites: Current students of engineering, post graduate science students and PhD students should have basic knowledge of GIS and Remote Sensing
