Global Triangular and Hexa-Pentagonal Grids Based on Tessellated Icosahedra
The icosa package provides tools to aggregate and analyze geographic data using grids based on tessellated icosahedra. The procedures can be set to provide a grid with a custom resolution. Both the primary triangular and their inverted penta- hexagonal grids are available for implementation. Additional functions are provided to position points (latitude-longitude data) on the grids, to allow 2D and 3D plotting, use raster data and shapefiles.
This is still the Beta version. Notes about found bugs and suggestions are more than welcome!
