Discrete Global Grid Systems with quadrangular cells as reference frameworks for the current generation of Earth observation data cubes [PDF]
Environmental Modelling and Software, 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.

Discrete Global Grid Systems as scalable geospatial frameworks for characterizing coastal environments [PDF]
Environ Model Softw, 2021 Data portals and services have increased coastal water quality data availability and accessibility. However, tools to process this data are limited – geospatial frameworks at the land-sea interface are either adapted from open- water frameworks or ...

Drivers of global irrigation expansion: the role of discrete global grid choice [PDF]
Hydrology and Earth System SciencesGlobal statistical irrigation modeling relies on geospatial data and traditionally adopts a discrete global grid based on longitude–latitude reference. However, this system introduces area distortion, which may lead to biased results.

Resolution Adaptive Vector Rasterization in Discrete Global Grid Systems
, 2022 Discrete Global Grid Systems (DGGS) are relatively new globe-based digital earth systems capable of integrating large geospatial datasets. In this report, we describe a new algorithm for rasterizing vector data to DGGS that relies on the hierarchical property of DGGS and adaptively changes to coarser rasterization to reach to target resolution high ...
