General Method for Extending Discrete Global Grid Systems to Three Dimensions
ISPRS International Journal of Geo-Information, 2020 Geospatial sensors are generating increasing amounts of three-dimensional (3D) data. While Discrete Global Grid Systems (DGGS) are a useful tool for integrating geospatial data, they provide no native support for 3D data.

ISPRS International Journal of Geo-Information, 2022 DGGS (Discrete Global Grid System) has many subdivision models and coding methods. Due to the lack of underlying consistency of different DGGS codes, most of them are converted through longitude–latitude, which greatly reduces the interoperability ...

A Topology Preserving Gridding Method for Vector Features in Discrete Global Grid Systems
ISPRS International Journal of Geo-Information, 2020 Topological distortion seriously affects spatial cognition. To solve this problem caused by the integration of vector features in discrete global grid systems (DGGs), a topology-preserving gridding method for vector features is proposed.
