PROJ implementation of the Mayotte deformation model (2018–2022)

A ground surface deformation model has been calculated to reconstruct the time-space distribution of ground displacement caused by the volcano-tectonic crisis that impacted Mayotte over the period 2018-2022.

In this dataset, the model is provided in proj format (https://proj.org) to facilitate its usage.

Additionnal proj files are available on the website https://geodesie.ign.fr/index.php?page=mayottedeformation. They allow the deformation model to be used with other coordinate reference systems. The new RGM04 to RGM23 transformation is also provided for use in PROJ.
