FDBNS ISO 19170-1:2021 Geographic information — Imagery and gridded data

The Bahamas Bureau of Standards and Quality (BBSQ) is in the enquiry phase of developing the following standards that have been prepared by the Technical Committee comprising of technical experts from a wide cross section of stakeholders. The standard being issued for public comment, in accordance with the provisions set out in the Standards Act, Chapter 338 (2006), and in keeping with the international best practices and standards development procedures. Please note that these standards should not be reprinted or used for any other purpose other than review and public comments. This is due to the documents being copyrighted by ISO and being the sole property of the Bahamas Government.

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.
