Semiregular Degenerate Refinement for 3D Discrete Global Grid Systems
… of the surface of the Earth, known as Discrete Global Grid Systems (DGGS), have proven to be useful tools for integrating data on the Earth's surface; however, they have no native support for 3D data. Instead, a 3D version of this data structure is needed. An Earth-centric 3D DGGS that …

Hexagonal Discrete Global Grid Systems in Topographical and Hydrological Modeling
Geographic Information Systems (GIS) have dominated geospatial analysis since the 1960s, where spatial phenomena were normally represented by individual thematic layers at a specific resolution, and commonly projected to a two-dimensional Cartesian coordinate system for analysis. Discrete Global …

Real-Time Multiresolution Management of Spatiotemporal Earth Observation Data Using DGGS
… challenges, this thesis adopts a triangular Discrete Global Grid System (DGGS) as the foundation for a spatiotemporal data management framework. The hierarchical and globally consistent structure of DGGS enables efficient multiresolution representation and indexing of spatial data, while …
