Description
This module aims to provide the basics of the principles of positioning and mapping of topography. The basic knowledge of GNSS and laser positioning methods are detailed in the course and then used in the field and during practical work. Finally, a project work will allow students to implement the practical and theoretical knowledge seen at the beginning of the module and especially to better understand the complementarity and accuracy of geodesy measurements.
Course content:
- Introduction from ground geodesy to space geodesy
- Geodesy reference frames
- Traditional ground geodesy tools
- The GNSS positioning system
- Geodesy applications (active tectonics, landslides, anthropic deformation...)
- Topography measurement (DTM, LIDAR, ...)
Objectives
- Theoretical approach: physical principles of measurements and errors (CM)
- Fieldwork on a case study: multi-instrumental (Theodolite levelling and geodimeter, GNSS, LIDAR, DTM)
- Project work: data combination and interpretation (TP / TD / personal work)
Necessary pre-requisites
Required prerequisites* : None
Recommended prerequisites*:
- Basic statistics (mean, stdev, histogram and some distributions)
- Python basics (loop, variable, array, read ascii file)
- Geographic projection and coordinate system
- Altitude (geoid) and height (ellipsoid)
Knowledge control
100% Continuous control in the form of MCQs, TP report, Field report
