The proposed course provides detailed understanding about Geographic Information Systems and their applications in Civil Engineering and Earth Sciences. All aspects starting from data input to modelling would be discussed in this course. Further, in the proposed course various datasets including 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, post graduate and doctoral studentsPREREQUISITES : Current students of engineering, post graduate science students and PhD students should have basic knowledge of computersINDUSTRIES SUPPORT :Geoinformatics companies, e.g NIIT, ESRI India, Leica Geoinformatics, MapmyIndia, ISRO, etc.
