Applied open-source Discrete Global Grid Systems
AGILE: GIScience Series, 2022 Abstract. Discrete Global Grid Systems (DGGS) are spatial reference systems that use a hierarchical tessellation of cells to partition and address the globe and provide alternative spatial data format and indexing methods as compared to traditional vector and raster spatial data.

Efficient Calculation of Distance Transform on Discrete Global Grid Systems
ISPRS International Journal of Geo-Information, 2022 Geospatial data analysis often requires the computing of a distance transform for a given vector feature. For instance, in wildfire management, it is helpful to find the distance of all points in an area from the wildfire’s boundary. Computing a distance

Area and shape distortions in open-source discrete global grid systems
Big Earth Data, 2022 A Discrete Global Grid System (DGGS) is a type of spatial reference system that tessellates the globe into many individual, evenly spaced, and well-aligned cells to encode location and, thus, can serve as a basis for data cube construction.

Wāhi, a discrete global grid gazetteer built using linked open data
International Journal of Digital Earth, 2017 Discrete global grid systems have become an important component of Digital Earth systems. However, previously there has not existed an easy way to map between named places (toponyms) and the cells of a discrete global grid system. The lack of such a tool
