This document supports the definition of: A Discrete Global Grid Systems (DGGS) core comprising: an RS using zonal identifiers with structured geometry, and functions providing import, export and topological query, Common spatio-temporal classes for geometry, topology, RS using zonal identifiers, zonal identifiers and zones, based on ISO19111 CRS. The spatio-temporal scope is constrained to: spatial elements that are invariant through all time, and temporal elements that are invariant across all space. Equal-Area Earth Reference Systems (EAERSs) for Equal-Area Earth DGGS.
