International Journal of Digital Earth, 2020 The foundation of modern Digital Earth frameworks is the Discrete Global Grid System (DGGS). To standardize the DGGS model, the Open Geospatial Consortium (OGC) recently created the DGGS Abstract Specification, which also aims to increase usability and ...

The rHEALPix Discrete Global Grid System [PDF]
IOP Conference Series: Earth and Environmental Science, 2016 In light of the new standard for Discrete Global Grid Systems (DGGS) currently being proposed by the Open Geospatial Consortium (OGC), we revisit our earlier work on defining the rHEALPix DGGS. This paper briefly restates the definition of the rHEALPix DGGS and shows how the cell geometries, and schema for cell identifiers are both compliant with the ...

Area and shape distortions in open-source discrete global grid systems
Big Earth Data, 2022 A Discrete Global Grid System (DGGS) is a type of spatial reference system that tessellates the globe into many individual, evenly spaced, and well-aligned cells to encode location and, thus, can serve as a basis for data cube construction.

On the isolatitude property of the rHEALPix Discrete Global Grid System [PDF]
Big Earth Data, 2019 Digital Earth frameworks provide a way to integrate, analyze, and visualize large volumes of geospatial data, and the foundation of such frameworks is the Discrete Global Grid System (DGGS).

Enhancing Authalic Latitude Calculation for the rHEALPix DGGS
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingDiscrete global grid systems (DGGSs) enable georeferencing spatial data directly on the surface of the ellipsoid by linking data to areal cells with unique identifiers.

Discrete Global Grid Systems with quadrangular cells as reference frameworks for the current generation of Earth observation data cubes [PDF]
, 2023 Discrete Global Grid Systems are spatial reference frameworks that associate information to multi-resolution grids of uniquely identified cells; they are proposed as mechanisms to facilitate the efficient integration of heterogeneous spatial data.

Open-source DGGS comparison data supplement
, 2022 A DGGS is a type of spatial reference system that partitions the globe into many individual, evenly spaced, and well-aligned cells to encode location. We calculated normalized area and compactness of cell geometries for 5 open-source DGGS implementations

Enabling a Digital Earth for methane emissions management with equal-area discrete global grids
International Journal of Digital EarthWe develop a spatially explicit methane inventory for Alberta’s upstream oil and gas sector using the rHEALPix Discrete Global Grid System. The objective is to demonstrate an equal-area, hierarchy-aware framework that assigns facility-reported emissions ...
