In order to integrate the different datasets into the DGGS, several methods were required and are described in …
The ISEA4H grid used in this paper is generated based on icosahedral structure, which has fivefold symmetry. In this grid, by rotating the coordinate system all the grid points on a face can coincide with the positions of all the grid points on other faces. This is considered an important advantage of the ISEA4H compared with the geographic ...
