Google’s S2, geometry on the sphere, cells and Hilbert curve | Terra Incognita
Google’s S2, geometry on the sphere, cells and Hilbert curve Update – 05 Dec 2017: Google just announced that it will be commited to the development of a new released version of the S2 library, amazing news, repository can be found here. Google’s S2 library is a real treasure, not only due to its capabilities for spatial indexing but also because it is a library that was released more than 4 years
GitHub - google/open-location-code: Open Location Code is a library to generate short codes, called "plus codes", that can be used as digital addresses where street addresses don't exist.
Codes are made up of a sequence of digits chosen from a set of 20. The digits in the code alternate between latitude and longitude. The first four digits describe a one degree latitude by one degree longitude area, aligned on degrees. Adding two further digits to the code, reduces the area to 1/20th of a degree by 1/20th of a degree within the previous area. And so on - each pair of digits reduces
