This document supports the definition of:

  1. A Discrete Global Grid Systems (DGGS) core comprising:

    1. an RS using zonal identifiers with structured geometry, and

    2. functions providing import, export and topological query,

  2. 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:

    1. spatial elements that are invariant through all time, and

    2. temporal elements that are invariant across all space.

  3. Equal-Area Earth Reference Systems (EAERSs) for Equal-Area Earth DGGS.
