Is there any alternative to Google's S2 geometry library? It looks it was updated 4 years back and hardly any documentation.
I need a library to divide cities into zones of the area I need. S2 looks good solution, but its documentation is very poor. I have even no clue how to use it. I am looking at its Java library which will be compatible with the project I am doing.
If no alternative, any pointers how to start on S2? Like, how do I create cells with IDs of the resolution I need? How do I use them to search for the proximity given a point??
