Add matplotlib mpl_toolkits.natgrid package
|Reported by:||ccrook||Owned by:||alexbruy|
The mpl_toolkits.natgrid module adds more robust triangluation to matplotlib. From the matplot lib documentation for the griddata function (used in at least one Quantum GIS plugin!) ...
"The triangulation algorithm in this package is known to fail on some nearly pathological cases. For this reason, a separate toolkit (mpl_tookits.natgrid) has been created that provides a more robust algorithm fof triangulation and interpolation. This toolkit is based on the NCAR natgrid library, which contains code that is not redistributable under a BSD-compatible license. When installed, this function will use the mpl_toolkits.natgrid algorithm, otherwise it will use the built-in matplotlib.delaunay package"
In this case it seems not difficult to find "nearly pathalogical".
I'm not sure what the implication of the license would be for OsGeo4W? Does this prohibit its inclusion?
The natgrid matplotlib toolkit can be downloaded from http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=142792
