DESCRIPTION:Mankind has been flattening the Earth for more than two thousan
 d years to represent and process geo-spatial data. This practice has impos
 ed relevant penalties in accuracy with the distortions inherent to map pro
 jections. An holistic approach to global geo-spatial was never really tack
 led.\n\nBut a new era is dawning. Computer Systems are finally brewing the
  impact on geo-spatial information the were always meant to have. As geo-s
 patial data are no longer stored on flat sheets\, the distortions and liab
 ilities of traditional cartography can be addressed. \n\nSince 1990 resear
 chers and computer programmers have worked on methods and models to partit
 ion the surface of the Earth\, paving the way for a modern representation 
 of geo-spatial data. Broadly known as Discrete Global Grid Systems (DGGS) 
 these models map any location on the surface to both a unique logical inde
 x and a geodetical zone. These zones form a regular or quasi-regular parti
 tion of the Earth's surface in its entirety\, and may be created at differ
 ent sizes or scales (also known as grid resolutions).\n\nIn recent years t
 he number of institutions and enterprises adopting or developing DGGSs has
  erupted\, leading to numerous tools and implementation\, progressively ap
 proaching the expectations of regular GIS users. Moreover\, members of the
  OGC have developed two standards\, an abstract DGGS specification and jus
 t this year a data provision API. These developments usher a new era\, in 
 which most users will have some means of working with DGSSs. \n\nThis addr
 ess presents in first place a brief history of DGGS. It then lays out the 
 current spectrum of DGGS tools and their applications. It closes with note
 s on expected developments in the near future.
