Digital Land Surveying and Mapping

Digital Land Surveying and Mapping. Instructor: Prof. Jayanta K. Ghosh, Department of Civil Engineering, IIT Roorkee. The objective of the course is to provide basics of digital surveying and mapping of earth surface using total station, GPS and mapping software. The course starts tith introduction to land surveying followed by fundamentals of total station and its working and measurements for land surveying. Then, fundamentals, working and measurements using GPS for land surveying will be discussed. Followed by mapping fundamentals, digital surveying procedure, working, data reduction etc. Finally, the course will deal with working and demonstration of a digital land surveying and mapping of an area.
