Positioning & Remote Sensing

This module aims to provide a basic understanding of the principles of topographic positioning and mapping. Basic knowledge of GNSS and laser positioning methods is covered in detail in lectures, followed by fieldwork and practical exercises. Finally, project work will enable students to apply the practical and theoretical knowledge acquired at the start of the module, and above all to gain a better understanding of 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, anthropogenic deformation, etc.)
- Measuring topography (DTM, LIDAR, etc.)

- Theoretical approach: physical principles of measurement and errors (CM)
- Fieldwork on a case study: multi-instrument (theodolite levelling and geodimeter, GNSS, LIDAR, MNT)
- Project work: data combination and interpretation (TP / TD / personal work)

Prerequisites*: None

Recommended prerequisites* : 

- Basic statistics (mean, stdev, histogram and some distributions)
