Python-geotiepoints is a Python module that interpolates (and extrapolates if needed) geographical tiepoints into a larger geographical grid. This is useful 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 accommodate for satellite data, but the package should be generic enough to be used for any kind of data.

In addition python-geotiepoints provides a fast multilinear interpolation of regular gridded data using Cython.
