H3/PostGIS: Hands-on example – Spatialists – geospatial news

Darafei Praliaskouski, member of the #PostGIS PSC, walks through an interesting hands-on case study of modelling #LoRa radio tower range in the mountains of Georgia using #H3 and PostGIS. The example covers data preparation, #DGGS indexing, and spatial analysis, and offers some food for thought.

AI-ready OGC standards – Spatialists – geospatial news

The #OGC ran an #AI-#DGGS pilot on disaster management and derived five pillars for geospatial AI readiness from it: tool-ability, machine-readable metadata, guardrails, reproducibility, and trust & security. Among the interesting follow-up work items: enabling non-DGGS clients, treating the time dimension as a first-class topic alongside space, and cataloging which spatial analysis functions should be available in a standardized #DGGS-based manner.

@jsonsingh Don’t limit yourself to the above mentioned ones of our are interested in #DGGS - learn about actual DGGS and gridding concepts and not a handful of fancy technologies, look at OGC API DGGS, look at HEALPIX, DGGAL, GeoPlegma, DGGRID, ISO DGGS definitions

I am looking to learn more about #DGGS and use cases surrounding to it. If you think your #geospatial data could some #h3, #a5 or #s2 sprinkle on top, please reach out.

Using Uber H3 Indexing Library in Postgres for Geospatial Data Analytics

Introduction H3 is a hierarchical grid system designed to efficiently index and organize geospatial data. It divides the Earth’s surface into hexagonal cells of various sizes, creating a hierarchical structure that allows for spatial indexing and querying. In context to postgres, uber h3 can be used to represented your spatial data as h3 indexes which are 64bit integers which can be used to turn your spatial operations into relational operations.
