The coordinate calculation allows to convert LV95, LV03 and WGS84/GPS coordinates.

Usage

To use the coordinate converter within ERPNext, include it like this

from erpnextswiss.erpnextswiss.swisstopo import GPSConverter

Then, create your instance and use as you like

converter = GPSConverter()
# Coordinates
wgs84 = [47.50564, 8.72413, 0]

# Convert WGS84 to LV03 coordinates
lv03 = converter.WGS84toLV03(wgs84[0], wgs84[1], wgs84[2])
