Indexing Mixed Aperture Icosahedral Hexagonal Discrete Global Grid Systems
ISPRS International Journal of Geo-Information, 2020 Discrete global grid systems (DGGSs) are an emerging multiresolution 3D model used to integrate and analyze big earth data. The characteristic of multiresolution is usually realized by hierarchically subdividing cells on the sphere using certain ...

Duality and Dimensionality Reduction Discrete Line Generation Algorithm for a Triangular Grid
ISPRS International Journal of Geo-Information, 2018 Vectors are a key type of geospatial data, and their discretization, which involves solving the problem of generating a discrete line, is particularly important. In this study, we propose a method for constructing a discrete line mathematical model for a

A global hierarchical and Equal-Area Sphere Grid and Its Geometry Distortion Analysis [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 A spatial data management and analysis frame is required for global problem application. Global Discrete Grid (GDG) has seamless, excellent hierarchy characteristics. GDG has been used for spatial data management, indexing and cartographic generalization.

Effective Local-Global Upscaling of Fractured Reservoirs under Discrete Fractured Discretization
Energies, 2015 The subsurface flow in fractured reservoirs is strongly affected by the distribution of fracture networks. Discrete fracture models, which represent all fractures individually by unstructured grid systems, are thus developed and act as a more accurate ...
