Crunching Data In GeoServer with Discrete Global Grid Systems (DGGS)
2021-09-30, 09:30–10:00, Buenos Aires

Discrete Global Grid Systems are a way to tessellate the entire planet into zones sharing similar characteristics, with multiple resolutions to address different precision needs, allowing integration of data coming from different data sources, and on demand analysis of data.

Come to this presentation to have an introduction to the DGGS concepts, learn when they are a good fit for a specific problem, and get an update on their implementation in GeoServer.

GeoServer is a web service for publishing your geospatial data using industry standards for vector, raster and mapping. It powers a number of open source projects like GeoNode and geOrchestra and it is widely used throughout the world by organizations to manage and disseminate data at scale.

Discrete Global Grid Systems are a way to tessellate the entire planet into zones sharing similar characteristics, with multiple resolutions to address different precision needs, allowing integration of data coming from different data sources, and on demand analysis of data.

The presentation will introduce: * Basic DGGS concepts * The Uber H3 and the rHealPix DGGSes, comparing and contrasting their structure and use cases * A OGC API exposing DGGS for data access, and another, DAPA, for data analysis * GeoServer implementations of the DGGS concepts and APIs, based on a ClickHouse OLAP database.

Come to this presentation to have an introduction to the DGGS concepts, learn when they are a good fit for a specific problem, and get an update on their implementation in GeoServer.
