DGGRID Authalic conversion clarity and DGGAL code examples #5
Description
- to apply authalic conversion to the WGS84 ellipsoid instead of the spherical approximation
- a rotation of the base icosahedron of 0.05 degrees to align the vertices better with water bodies through a specific parameter in DGGRID
In practice this means that IGEO7 as described in the original publication is not the same as the ellipsoid-adjusted IGEO7 version, though both can be generated through dggrid4py, and DGGAL only provide the corrected ellipsoidal version
