A New Reference System “Discrete Global Grid System”

One of the basic tasks of geodesy science is undoubtedly to create the model closest to the reality of the earth. Many models have been tried from past to present and of course they all have their own pros and cons. Nowadays, however, the Open Geospatial Consortium (Geospatial Consortium) has announced a new reference system called the Discrete Global Grid System. If you say what the form looks like, we are actually switching to a fully detailed soccer ball model.

Although the OGC Standard was prepared at the beginning of 2017 under conditions that set the basic rules for recognition, the standard is accepted by some authorities. The new standard describes the reference guide to optimize the loss of geospatial data during projection and to seamlessly integrate GIS data from various sources. The objective of the DGGS is to quickly integrate spatial data without the hassle of working with predicted coordinate reference systems.

Essentially, the new reference grid is a multi-faceted grid of equal-area grids to form a hierarchical mosaic of the entire world. Although the new reference system seems very promising, it is curious how this new standard will change the work of Geographical Information Systems and how GIS developers and analysts will model GIS data. subject. Can this standard be another alternative reference system, or will it completely change the traditional coordinate system and become our “new toy”? We’ll wait and see…
