ISO 19170:2021 Geographic information – Discrete Global Grid Systems Specifications – Part 1: Core Reference System and Operations, and Equal Area Earth Reference System
CDN $422.00
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 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.
