# gauss-krueger

JavaScript module for converting [*Gauß-Krüger*-coordinates](https://en.wikipedia.org/wiki/Gauss%E2%80%93Kr%C3%BCger_coordinate_system) into WGS84 latitide and longitude, and vice versa. Supported zones: **GK2** *(EPSG:31466)*, **GK3** *(EPSG:31467)*, **GK4** *(EPSG:31468)*, **GK5** *(EPSG:31469)*, based on the the **Bessel** ellipsoide and **Potsdam / Rauenberg** datum.

## Usage

```javascript

const gk = require('gauss-krueger')

let wgs84 = gk.toWGS({x: 4591270, y: 5819620}) // {longitude: 13.34255019849783, latitude: 52.50210050984162}

let gk = gk.toGK({longitude: 13.4, latitude: 52.5}) // {x: 4595175.488530577, y: 5819460.402152777}

// The script guesses the GK zone based on the input coordinate longitude.

// You can also supply a zone directly via the zone parameter:

let gk5 = gk.toGK({longitude: 13.4, latitude: 52.5}, 5) // {x: 5391482.283752493, y: 5819737.58836849}

```
