GeoJSON.NET

GeoJSON.Net is a .NET library for the RFC 7946 The GeoJSON Format and it uses and provides Newtonsoft Json.NET converters for serialization and deserialization of GeoJSON data.

Installation & Usage

GeoJSON.Net NuGet package: Install-Package GeoJSON.Net

Serialization

Position position = new Position(51.899523, -2.124156);
Point point = new Point(position);

string json = JsonConvert.SerializeObject(point);

Deserialization

string json = "{\"coordinates\":[-2.124156,51.899523],\"type\":\"Point\"}";

Point point = JsonConvert.DeserializeObject<Point>(json);

See the Tests for more examples.

Special considerations for ASP.Net Core 3.1+

System.Text.Json is the default (recommended) serializer. GeoJSON.Net does not play well with System.Text.Json and only supports Newtonsoft.Json

GeoJSON.Text is a fork of this repository and have been developed to support System.Text.Json.

If you still need to use Newtonsoft.Json in ASP.Net Core 3.1+, you must overwrite the default serializer.

add the "Microsoft.AspNetCore.Mvc.NewtonsoftJson" NuGet Package
add "services.AddControllers().AddNewtonsoftJson();" to your service configuration.
