H3.NET.Native

An idiomatic P/Invoke binding over Uber H3 v4.5.0 for .NET. The package bundles the native libh3 for the supported runtimes, so consumers do not build or ship the native library themselves.

The NuGet package id is H3.NET.Native (the GitHub repository is H3.NET.Native).

Install

dotnet add package H3.NET.Native

At a glance

  • Target frameworks: net10.0, net8.0.
  • Bundled native runtimes (RIDs): linux-x64, linux-arm64, linux-musl-x64, osx-arm64, win-x64 (Intel macOS, osx-x64, is not currently bundled).
  • Angular units: all latitude/longitude values are in degrees (not radians).
  • API surface: the public H3.NET.Native namespace. The internal H3.NET.Native.Interop marshalling layer is intentionally not documented.

Quickstart

using H3.NET.Native;

// Index a coordinate (near the Ferry Building, San Francisco) at resolution 9.
var sanFrancisco = new LatLng(LatitudeDegrees: 37.7752, LongitudeDegrees: -122.4188);
H3Index cell = H3Index.FromLatLng(sanFrancisco, resolution: 9);

Console.WriteLine(cell);            // 08928308280fffff
Console.WriteLine(cell.Resolution); // 9
