Transformation and calculation services

REFRAME

With REFRAME you can convert coordinates to position and/or height. Here you can use the REFRAME service online.

NAVREF

With NAVREF you can convert Swiss national survey (LV) coordinates into global WGS84 GPS coordinates. Enter the desired coordinates and click on “Calculate”.

REST web geoservices (REFRAME Web API)

swisstopo’s REST geoservices support the transformation between ellipsoidal WGS84 data and the Swiss LV03 and LV95 coordinates.

KML generation

With swisstopo’s KML generation geoservice you can convert a file with Swiss national coordinates or GPS data into a KML file.

Magnetic declination

Here you can calculate the magnetic declination, compass declination and other values of the earth’s magnetic field, e.g. inclination or field strength.
