Discussion from Pangeo Discourse on DGGS use with Pangeo.
Pangeo discourse on "Discrete Global Grid Systems (DGGS) use with Pangeo"
Pangeo discourse announcement Show & Tell on "October 6, 2022: DGGS and their potential impact in Geoscience and Geospatial communities"
Github repository with examples used during the Pangeo Show and Tell - 06. Oct., 2022 on "DGGS and their potential impact in Geoscience and Geospatial" by Alexander Kmoch (Landscape Geoinformatics Lab, University of Tartu, Estonia). Twitter: @Lgeoinformatics │ @allixender
This is the shared document we use for all the Pangeo Show and Tell. We collect information, Q&A and feedback. Each Show and Tell has its own sub-section.
Conda environment for running DGGS notebook examples.
Jupyter Notebook demonstrating how to perform Spatial Data Analysis with H3.
A Discrete Global Grid Systems (DGGS) is a unique type of spatial reference system comprising of a hierarchy of uniquely identifiable discrete grid cells that span the globe at multiple resolutions. A DGGS can support efficient management, storage, integration, exploration, mining, and visualisation of large geospatial datasets, and several systems of tesselation and indexing schemes exist. The main topic of this session is to introduce the audience to the theoretical background of Discrete Global Grid Systems (DGGS), current real-world implementations and exemplary use cases. This includes grid generation, data indexing and sampling with DGGRID, and some spatial analysis with with H3 and rHealPix.
