Geospatial Data Analysis for Global Maritime Risk Assessment Using the Discrete Global Grid System [PDF]

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The effective management of the safety of navigation by coastguards is challenged by the complexity in quantifying and describing the relative risk of accidents occurrence. The discovery of patterns in observation data is reliant on the collection and analysis of significant volumes of relevant heterogenous spatial datasets.

A discrete square global grid system based on the parallels plane projection

International Journal of Geographical Information Science, 2009
We developed a direct partitioning method to construct a seamless discrete global grid system (DGGS) with any resolution based on a two-dimensional projected plane and the earth ellipsoid. This DGGS is composed of congruent square grids over the projected plane and irregular ellipsoidal quadrilaterals on the ellipsoidal surface.

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.

Datacubes: A Discrete Global Grid Systems Perspective

Cartographica, 2019
Datacubes are increasingly being implemented to manage big data workflows efficiently, particularly those for processing geospatial data. However, there is confusion in both the definition of the term “datacube” and the choices for how it is implemented.
