Hello all, I'm Rémi, I'm a working colleague of Martin and work among other things on Mathematical GIS projections.
Moreover, into Geomatys compagny, I work more precisely on Geotiff and rasters data using objects like iterators, color interpretation with style, and also some other mathematical tools like R-Tree and more ...
