Scope

This part of ISO 19170 supports the definition of:

- a reference system using geometry with zonal identifiers, and
- functions providing import, export and topological query,

Common Classes for spatio-temporal geometry, topology, zones, and zonal identifiers based on ISO 19111 coordinate systems. The spatio-temporal scope is constrained to:

- spatial elements that are invariant through all time, and
- temporal elements that are invariant across all space.
