Discrete Global Grid System (DGGS) is a spatial reference system that uses a hierarchy of equal area tessellations to partition the surface of the Earth into grid cells or their analogous lattice points. In this way, information recorded about phenomena and observation measurements at a location can be easily referenced to the explicit area of the associated cell, integrated with other cell values, and provide statistically valid summaries based on any chosen selection of cells. In order for a grid based global spatial information framework to operate effectively as an analytical system it should be constructed using cells that represent the surface of the Earth uniformly. With equal area partitioning, spatial analyses can be replicated consistently anywhere on the Earth independently of resolution or indeed scales. The quadrilateral-based approach of the rHEALPix DGGS was found more suitable for a geospatial application as it mirrored the geographic grid more closely.

The AusPIX DGGS is an Australian Government implimentation of the rHealpix DGGS model.
