Python-geotiepoints is a python modules that interpolates (and extrapolates if needed) geographical tiepoints into a larger geographical grid. This is usefull when the full resolution lon/lat grid is needed while only a lower resolution grid of tiepoints was provided.
Some helper functions are provided to accomodate for satellite data, but the package should be generic enough to be used for any kind of data.
The full documentation of the module can be found here: http://adybbroe.github.com/python-geotiepoints/.
