Global Grids for Statistical Data

7 September 2022 - 14.00 Geneva time

Recording (on YouTube)

This coffee talk featured the following presentations, followed by an open discussion:

1) Kevin Sahr (Southern Oregon University) and Richard Barnes – “Getting Started with DGGRID:  Everything you need to know to begin using hexagonal DGGs” (see also Kevin's demonstration files)

DGGRID is one of the most widely used tools for working with hexagonal Discrete Global Grids (DGGs). We’ll give a quick overview of DGGRID, and then demonstrate how to use it to generate and populate a DGG.

2) Alexander Kmoch (University of Tartu) –  “SAGEGRID - Spatial Analysis and Areal Statistics as a Service with Discrete Global Grid Systems”

SAGEGRID is the acronym of a EU Horizons grant proposal that aims to apply Discrete Global Grid Systems to the European Data Strategy. The concept revolves around a spatial data trade paradigm based on DGGS to support API-based data markets. DGGS software is becoming increasingly available, and cell ID-based encoding of data allows targeted and seamless data selections, extraction, and tabular alignment which is ideal for aggregation in downstream analytics and machine-learning for value-added data products in a thriving data market.
