FINELTRA data viewer

You can use the FINELTRA data viewer to assess the precision of the transformation between the LV03 and LV95 global reference frames and thereby evaluate the accuracy of positioning with swipos® in the LV03 reference frame (service LV03/LN02).

The new CHENyx06 triangular transformation network enables you to transform coordinates from the old Swiss LV03 coordinate system to the new LV95 system and vice versa. The FINELTRA data viewer shows the triangular transformation network and the transformation reference points on an interactive map, thus enabling you to assess how accurately the conversion between the LV03 and LV95 reference frames and, indirectly, the connection to international reference systems such as WGS84 or ETRS89 can be carried out. WGS84 is used as the reference frame for GPS observations as well as in Google Earth and Google Maps, for example.

For users of the swipos positioning service with the real-time FINELTRA option (service LV03/LN02), the empirical accuracy map indicates the attainable positioning accuracy in the LV03 reference frame (without local adjustment) for all regions in Switzerland.
