Map restoration: latest advances.

@inproceedings{121_lallier,
 abstract = { In geology, most of the tectonic deformations might be described by a combination of two main
models of deformation: 
exural slip and shear. These two end-models have been used to develop
di
erent map restoration methods. In 
exural slip context, the restoration is often based on a
parameterization of the surface. In this paper, two main aspects to improve the applicability of
map restoration are presented.
Through a sensitivity study on subdivision surfaces, we show that the mesh resolution has to
adapted to the complexity of the model to show consistent results. This study also exhibits that the
strain is sensitive to the location of the seed of the parameterization, which is the point from which
restoration is initiated. Therefore, we propose the user to provide the seed location. If not, we also
introduce a new method to make map restoration independent on the seed location: several seed
locations are set on the geological horizon to compute restoration realizations, and the resulting
restoration vectors are averaged. It also highlights the importance of the pin vector orientation.
Another proposal is to restore back not to a 
at geometry as usually performed, but to a target
paleotopography. Paleotopography may indeed be available for instance from facies information,
and in
uences restoration results. This new method combines two parameterizations, and uses a
matching of the target topography and the geological horizon in parametric space. },
