Popis
BS ISO 19170-1:2021
This standard BS ISO 19170-1:2021 Geographic information. Discrete Global Grid Systems Specifications is classified in these ICS categories:
- 35.240.70 IT applications in science
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.
