OGC DGGS Standard


Discrete Global Grid Systems are an Open Geospatial Consortium Standard
Abstract

15-104r5_Topic_21_Discrete_Global_Grid_Systems_Abstract_Specification


This document specifies the core Abstract Specification and extension mechanisms for Discrete Global Grid Systems (DGGS). A DGGS is a spatial reference system that uses a hierarchical tessellation of cells to partition and address the globe. DGGS are characterized by the properties of their cell structure, geo-encoding, quantization strategy and associated mathematical functions. The OGC DGGS Abstract Specification supports the specification of standardized DGGS infrastructures that enable the integrated analysis of very large, multi-source, multi-resolution, multi-dimensional, distributed geospatial data. Interoperability between OGC DGGS implementations is anticipated through implementation standards, and extension interface encodings of OGC Web Services.
