GeoTess

A GeoTess model is comprised of 2D triangular tessellations of a unit sphere with 1D radial arrays of nodes associated with each vertex of the 2D tessellations. Variable spatial resolution in both geographic and radial dimensions is supported. Users have considerable flexibility in how to define the data stored on the grid.

The GeoTess library is provided in Java and C++, with a C interface to the C++ library. The most recent release has been tested on Linux, with Mac and Windows versions coming soon. Source code and pre-compiled binaries are provided.
