Los DGGS y su importancia en el gobierno del dato
DGGS son las siglas de Discrete Global Grid System (Sistema de Rejilla Global Discreta). En este artículo se explica qué es exactamente un DGGS, por qué sus propiedades son relevantes para el dato, y cómo ciertas iniciativas están demostrando su valor.
DGGS en la práctica: quién los está usando
Aunque los DGGS pueden parecer un estándar reciente, varias organizaciones llevan años usando estos sistemas en producción con resultados muy concretos. Algunos ejemplos ilustrativos:
Uber con H3. H3 nació dentro de Uber para resolver un problema muy concreto: calcular precios dinámicos y casar oferta y demanda en cada ciudad. La compañía agrupa los millones de eventos diarios (viajes, peticiones, posiciones de conductores) en celdas hexagonales y, sobre esa rejilla, calcula tarifas, predice demanda y optimiza despachos. La librería es de código abierto desde 2018 y se ha convertido en estándar de facto en muchos sectores.
...
La buena noticia es que el ecosistema está madurando rápido: el estándar abstracto está consolidado, hay una API oficial, existen implementaciones abiertas —H3, S2, DGGAL, rHEALPix— y los pilotos como AI-DGGS demuestran que la pieza encaja con las arquitecturas modernas de datos e IA. La conversación, simplemente, ha empezado, y a las oficinas de gobierno del dato les corresponde liderarla en sus organizaciones.

Greetings from the #OGC members meeting - Helsinki Connect … in Helsinki 🍦🌎 Completed the first day of #interoperability #standards and #connecting . Already had fruitful conversations on #DGGS of course, global spatial IDs and #Europe data sovereignty

@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

• Hexagonal multi-structural elements enhance Earth's surface modeling precision.
• Integration of indexing and conversion rules improves geospatial data computation.
• DGGRID implementation shows increased precision in raster and vector data modeling.
• Addresses limitations in existing software for Earth observation data.
