Transition of reference frames LV03 - LV95: Combined transformation accuracy map
type: DataService
description: 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 national survey and cadastral data (frame of reference). Therefore, it is for instance possible to avoid a local adjustment…
description: This API provides access to the combined accuracy map for the transformation between the Swiss reference frames LV03 and LV95. It allows users to derive the accuracy of GNSS measurements, for example from the swipos positioning service, in LV03 (using real-time FINELTRA correction) or LV95, relative to national survey and cadastral reference data. The dataset supports assessment of positional accuracy across the country, helping determine where local adjustment to survey or cadastral data can be avoided. It is published by swisstopo, the Swiss Federal Office of Topography, and covers national territory under Switzerland's official geodetic reference frame infrastructure.
