Name: CH1903 to ETRS89-CHE [CHTRS95] (2)
Method: Geocentric translations (geog2D domain)
Remarks: Parameter values from CH1903+ to ETRS89-CHE [CHTRS95] (CT code 1509). Application of these parameters to CH1903 ignores the scale distortions in the CH1903 network, hence low accuracy. This transformation is also given as CH1903 to ensemble-based ETRS89 (code 1646).
