A fast grid generation algorithm for local irregular parts of hexagonal discrete global grid systems
Cartography and Geographic Information Science, 2023 Discrete Global Grid Systems (DGGS) provide a multi-resolution discrete representation of the Earth and are preferable for the organization, integration, and analysis of large and multi-source geospatial datasets.

Geodesic Discrete Global Grid Systems
Cartography and Geographic Information Science, 2003In recent years, a number of data structures for global geo-referenced data sets have been proposed based on regular, multi-resolution partitions of polyhedra. We present a survey of the most promising of such systems, which we call Geodesic Discrete Global Grid Systems (Geodesic DGGSs).

A comparison of intercell metrics on discrete global grid systems
Computers, Environment and Urban Systems, 2008Abstract A discrete global grid system (DGGS) is a spatial data model that aids in global research by serving as a framework for environmental modeling, monitoring and sampling across the earth at multiple spatial scales. Topological and geometric criteria have been proposed to evaluate and compare DGGSs; two of which, intercell distance and the ...

Datacubes: A Discrete Global Grid Systems Perspective
Cartographica, 2019Datacubes are increasingly being implemented to manage big data workflows efficiently, particularly those for processing geospatial data. However, there is confusion in both the definition of the term “datacube” and the choices for how it is implemented.

A Review of the Research on Discrete Global Grid Systems in Digital Earth
2022 IEEE 10th Joint International Information Technology and Artificial Intelligence Conference (ITAIC), 2022Discrete global grid systems (DGGSs) have been widely used in digital earth to simulation and manager massive geo-data. To sustainably develop and keep interoperability through the usage of DGGS, the Open Geospatial Consortium (OGC) make a series of ...

Applying discrete global grid systems to sensor networks and the Internet of Things
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017The rapid growth in global sensor networks is leading to an explosion in the volume, velocity and variety of geospatial and geoscientific data. This coupled with the increasing integration of geospatial data into our everyday lives is also driving an increasing expectation of spatial information on-demand, and with minimal delay.

A discrete global grid system for earth system modeling
International Journal of Geographical Information Science, 2017ABSTRACTTo support Earth system modeling, we propose a discrete global grid system that expresses multi-resolution spatial data. Specifically, a unified coding model that expresses a grid of nodes, edges, and cells is constructed for a triangular discrete global grid system.
