Pangeo Show-and-Tell presentation by Alexander Kmoch, Department of Geography of the University of Tartu, (Estonia).

**Bio**

**Alex Kmoch** is a Distributed Spatial Systems Researcher with many years of  
international experience in geospatial data management and web- and  
cloud-based geoprocessing with a particular focus on land use, soils,  
hydrology, and water quality. His interests include open standards and  
web-services for location-based data sharing, modelling workflows,  
machine learning, and interactive geo-visualisation. In his research on  
DGGSs, Alex looks at the challenges in indexing, storing and querying  
data via a DGGS to integrate, visualise and analyse arbitrary raster and  
vector data and perform ML workloads on DGGS-based datacubes. He was  
recently elected board member of the Estonian Geoinformatics Society  
(EstGIS) and European Co-Chair for the OGC University Domain Working  
Group. He is a member of the [Landscape Geoinformatics Lab at the  
Department of Geography of the University of Tartu, Estonia](https://landscape-geoinformatics.ut.ee/).

**Abstract**

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.

Looking forward to this! I think I’ll be in SF that day so this will be great to start the day with.
