Scope

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.
