nadar/swiss-coordinates

Converting swiss coordinates to Lat/Long global coordinates.

Convert WGS (Word Geodetic System) coordinates into CH (Swiss-Coordinates) and vice versa.

Wrapper class with composer support based on http://www.swisstopo.admin.ch/internet/swisstopo/de/home/products/software/products/skripts.html, _(*1)

Informations about coordinates:

• Lat/Long = Latitude And Longitude
• WGS = Word Geodetic System
• Lat = Y-Axis
• Long = X-Axis

Example swiss coordinates:

• Rigi: Y = 679520, X = 212273
• Zürich-Seebach: Y = 684592, X = 252857

Installation

composer require nadar/swiss-coordinates

Usage example:

use swisscoordinates\Converter;

echo Converter::CHtoWGSlat(679520, 212273); // 47.056709
echo Converter::CHtoWGSlong(679520, 212273); // 8.485306
