Liechtenstein; Switzerland.

code 1676

Accuracy 1.0 m (default)
3 parameters

Method: Geocentric translations (geog2D domain)

Remarks: Parameter values are from CH1903+ to CHTRF95 (1) (code 1509) assuming that CHTRF95 is equivalent to WGS 84. That transformation is also given as CH1903+ to ETRS89 (1) (code 1647). CHTRF95 is a realisation of ETRS89.
