Area and shape distortions in open-source discrete global grid systems
Big Earth Data, 2022 A Discrete Global Grid System (DGGS) is a type of spatial reference system that tessellates the globe into many individual, evenly spaced, and well-aligned cells to encode location and, thus, can serve as a basis for data cube construction.
