Geoid model CHGeo2004 in ETRS89
Swiss geoid model in the version of 2004 (CHGeo2004) in the reference system ETRS89. It forms the zero reference surface (approximated mean sea level) for height determination a...

Transition of reference frames LV03 - LV95: Combined transformation accuracy map
From the combined accuracy map can be derived the accuracy of GNSS data measured, e.g. with swipos positioning service, in LV03 (with real-time-FINELTRA) or LV95, compared to na...

Transition of reference frames LV03 - LV95: Coordinate changes LV03->LV95
The coordinate changes between the old frame of reference LV03 and the new one LV95, respectively the deformations from MN03, are represented in relation to Zimmerwald (BE): the...

Transition of reference frames LV03 - LV95: Triangular network (CHENyx06 and...
The triangular network of the national survey (FINELTRA-LV) was completed in the 90's and has permitted to transform geodata from LV03 to LV95 and vice versa with an accuracy of...

Low distortion area
During fieldwork in the official cadastral survey, a local adaptation must be made or proof must be provided that this is not needed. In low distortion areas, a local adaptation...

Planimetric control Points LFP1 (National Survey)
All spatial data is based on measurement points. It is recommended to use the so-called fixed control points for all technical works which need reliable and accurate position me...
