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.
