Attributes

Geodetic CRS: CH1903

Datum: CH1903

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: OGP

Information source: Bundesamt für Landestopografie swisstopo; www.swisstopo.ch. Aufbau der Landesvermessung der Schweiz 'LV95' Teil 3: Terrestrische Bezugssysteme und Bezugsrahmen. L+T 1999. Also at Eurogeographics http://www.crs-geo.eu/ to 1 decimal place precision.

Revision date: 2017-10-16

Scope: Parameter values from CH1903+ to ETRS89 (tfm code 1647) and are used as an approximation from CH1903 with a lesser accuracy of 1.5m which equates to the magnitude of distortions in the CH1903 network.

Remarks: In EPSG db v5.2 to v8.9 given to 1dm to accord with Eurogeographics precision ; the difference in output coordinates of cms is considered by swisstopo to be insignificant given the tfm accuracy. Superseded by CH1903 to ETRS89 (2) (tfm code 7674).

Method: Geocentric translations (geog2D domain)

Area of use: Liechtenstein; Switzerland.

Description: (674.374, 15.056, 405.346, 0.0, 0.0, 0.0, 0.0)
