CH1903 to ETRS89-CHE [CHTRF95] (1)

Koordinat Referans Sistemleri

Açıklamalar

Parameter values from CH1903+ to ETRS89-CHE [CHTRF95] (CT code 1647). Application of these parameters to CH1903 ignores the scale distortions in the CH1903 network, hence low accuracy. In EPSG db v5.2 to v8.9, parameter values were given to 1dm; the difference in output of cms is considered by swisstopo to be insignificant given the transformation accuracy. Superseded by CH1903 to ETRS89 (2) (CT code 7674).
