Lat / Lng to Gauss–Krüger coordinate system conversion in C#

🇩🇪 C# Functionality for converting Latitude and Longitude (WGS84) values to the Gauss–Krüger coordinate system (Gauß-Krüger-Koordinatensystem). *

* also sometimes referred to as GK or the German Grid System.

📱 This C# code has been derived from that used in my Grid Ref GK mobile app.

How to use

⬇️ Download the repository and open the LatLngToGaussKruger.sln file in Visual Studio.

▶️ Then run it.

✏️ Modify Program.cs to set the WGS84 Latitude and Longitude input variables - lat and lng.

Example

Functions.LLtoGaussKruger(53.551085, 9.993682, out gkEasting, out gkNorthing);

would return gkEasting = 3565935, gkNorthing = 5935969

Whilst the entire repository can be compiled and used as a C# / .NET Console App, these are the main files.

💻 Program.cs - the controller of the console app, showing you how to use the LLtoGaussKruger (double Lat, double Long, out double GKEasting, out double GKNorthing) function.

🔢 Functions.cs - the mathematical functions that perform the grid coordinate conversion.
