## OpenSky S2Geometry

This repository contains the C# code for handling S2 Geometry calculations used in OpenSky, published as a [nuget package](https://www.nuget.org/packages/OpenSky.S2Geometry/).

This is a fork from novotnyllc's C# port of Google's S2 Geometry Library from both Java and C++, the aim of this fork is to provide a shared version for both .net 4.8 and 5/6 with some added convinience methods

This library is can be used to create GeoHashes for fast querying. The Java version is used by AWS for 

GeoSpatial queries in DynamoDB.

S2 uses Hilbert Curves extensivly.
