Spherical Ranges and Parametrization of Geographic Shapes
Details
A collation of tools and metrics to characterize distribution data on the surface of a sphere or an ellipsoid. The primary group of these metrics is those that describe the extent of a distribution (geographic ranges). The calculation of geographic ranges can be executed using point coordinates data, vector polygons, as well as cells on a discretized sphere. Besides ensuring the use a geometrically correct implementations, the package offers the exploration of partial results for visual diagnostics. This is still the pre-alpha version. Notes about found bugs and suggestions are more than welcome!
