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). One approach in particular, the rHEALPix DGGS, has the rare property of distribution of cell nuclei along rings of constant latitude (or isolatitude rings ...

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 ...

Applied open-source Discrete Global Grid Systems
AGILE: GIScience Series, 2022 Abstract. Discrete Global Grid Systems (DGGS) are spatial reference systems that use a hierarchical tessellation of cells to partition and address the globe and provide alternative spatial data format and indexing methods as compared to traditional vector and raster spatial data.
