Landslide GPS data centre

Description of the service

The objective of the landslide GPS data centre is to propose a near-real time characterization of the displacements using permanent GPS stations. Several GPS receivers have been installed on active landslides (e.g. La Clapière and Séchilienne rockslides, Avignonet and Villerville rotational slides, Super-Sauze and La Valette mudslides) since a few years. These landslides show very different displacement rates (ranging from a few centimetres to several meters per year) and different kinematic regimes (e.g. continuous displacement of nearly constant rate or succession of periods of acceleration/deceleration).

For landslide monitoring, where the required accuracy is millimetric, GPS has been mainly used for repeated measurements, as a complement to conventional geodetic methods. Permanent monitoring is still not usually performed operationally in near-real time, and specific processing had to be developed.
