Disdyakis Triacontahedron Discrete Global Grid System
… this thesis, we explore the idea of creating a Discrete Global Grid System (DGGS) using a Disdyakis Triacontahedron (DT) as the initial polyhedron. We have adapted a simple, closed‑form, equal‑area projection to reduce distortion and speed up queries. We have also derived an efficient, …

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 …

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 …
