Full Description

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.
