A discrete global grid system for earth system modeling

International Journal of Geographical Information Science, 2017
ABSTRACTTo 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.

Geodesic Discrete Global Grid Systems

Cartography and Geographic Information Science, 2003
In 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, 2008
Abstract 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 ...

A spatial indexing method for the hexagon discrete global grid system

2010 18th International Conference on Geoinformatics, 2010
With the development of remote sensing technologies, computer friendly systems for the display and analysis of global geospatial information become more and more important. This paper concerns a method for computer representation and manipulation of global data based on multi-resolution subdivisions of regular polyhedra. A simple and efficient indexing

Applying discrete global grid systems to sensor networks and the Internet of Things

2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017
The 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.

Discrete global grid systems: generating algorithm and software model

SPIE Proceedings, 2006
Discrete global grid system (DGGS) is a promising data structure for global geo-referenced data sets based on regular, multi-resolution partitions of polyhedra. The equal-area DGGSs, however, have the important theoretical meaning and applied potential on large-scale remote sensing data processing and management.
