JavaScript module for converting Gauß-Krüger-coordinates 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.
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}If you found a bug, want to propose a feature or feel the urge to complain about your life, feel free to visit the issues page.
