Why Discrete Global Grid Systems (DGGS) Matter Now: From Grids to AI-Ready Geospatial Systems
February 25, 2026 11:00 am (Central Time)
Abstract
Discrete Global Grid Systems (DGGS) have shifted from theoretical models to operational infrastructure, thanks to recent OGC standards. The ISO 19170-1 standard (2021) and the OGC API – DGGS (2025) provide a shared foundation for interoperability, allowing DGGS to support consistent, scalable, and standards-based spatial services. These developments are critical for advancing AI-ready, digital-first spatial representation. The AI-DGGS Pilot, focused on flood risk in Manitoba’s Red River Basin, demonstrated how DGGS infrastructure aligned with OGC standards can integrate diverse datasets and support explainable, AI-driven disaster response. A live demo will showcase DGGS service interactions.
