Geographic information. Discrete Global Grid Systems Specifications -- Core Reference System and Operations, and Equal Area Earth Reference System
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 ISOÂ 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.
