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 ISO 19111 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.
