What is ISO 19170‑1— Discrete Global Grid Systems Specifications about?

ISO 19170‑1 is an international standard that deals with geographic information to help researchers more about the Earth reference system.

ISO 19170‑1 gives technical specifications such as terms, conventions, DGGS specification overview, common Spatio-temporal classes package, DGGS core package, equal-area Earth DGGS for explaining the Discrete Global Grid Systems Specifications.

ISO 19170‑1 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

Who is ISO 19170‑1— Discrete Global Grid Systems Specifications for?

ISO 19170‑1 on Discrete Global Grid Systems Specifications is useful for:

Geological organizations

Why should you use ISO 19170‑1— Discrete Global Grid Systems Specifications?

A single-parent global geometry is chosen to define the dimensionality and orientation of the region of space-time occupied by the DGGS. Discrete Global Grid Systems (DGGSs) provide a new way to organize, store and analyze Spatio-temporal data.

ISO 19170‑1 gives you the Spatio-temporal scope that is constrained to spatial classes that are invariant through all time, and to temporal classes that are invariant throughout space, which is flexible enough for a very large body of social and environmental modelling.

ISO 19170‑1 specifies data models for a consistent set of common Spatio-temporal classes, a DGGS core built on the common Spatio-temporal classes, and a DGGS EAERS (Equal-Area Earth RS). The Common Spatio-temporal Classes, DGGS Core, and Equal-Area Earth DGGS packages each have their own conformance classes with their associated specifications and requirements.
