Some questions about Open DGGS

[Peter_Krauss]

Creating a topic to discuss DGGS and similar “grid technologies”.

If you’re not familiar with DGGS, here are some links:

• ISO 19170-1: “Geographic information — Discrete Global Grid Systems Specifications — Part 1: Core Reference System and Operations, and Equal Area Earth Reference System”, from 2021, ISO 19170-1:2021 - Geographic information — Discrete Global Grid Systems Specifications — Part 1: Core Reference System and Operations, and Equal Area Earth Reference System

• OGC Topic 21: “Discrete Global Grid Systems - Part 1 Core Reference system and Operations and Equal Area Earth Reference System”, version 2 from 2021 (link www.opengis.net/doc/AS/dggs/2.0); version 1 from 2017 (link www.opengis.net/doc/AS/dggs/1.0).

• DGGS APIs: https://docs.ogc.org/per/20-039r2.html (implementation p1)

Is there anything in particular you would like to discuss about DGGS?

We have had an ongoing discussion about DGGS on this forum for several years in this thread:

Discrete Global Grid Systems (DGGS) use with Pangeo

Dear all, there has been increasing interest in working with DGGS, e.g. local to global spatial statistics and analysis, and connecting the DGGS and Pangeo communities. For example, Uber’s H3 is one type of DGGS that has been very popular recently. I’d like to use the chance to start communications around how DGGS are useful and how they connect to and bridge traditional cartographic GIS (flat earth, Cartesian gridding). The core concept of DGGSs is to discretize the Earth into a globally conti…
