The definition of the FINELTRA- triangulation CHENyx06 was elaborated during several years in
collaboration of the national and the cantonal surveying authorities.
A large amount of triangles was defined unter analysing the local deformation situation. The used
triangulation definition points (TSP) are at least national and cantonal geodetic control points (LFP1
and LFP2) and also reliable controllpoint from local geodetic networks and some virtuall definition
points. The mean size of triangles is about 6.5 km^2.
For the controlling of the accuracy about 45'000 checking points (local controll point and property
border points). The mean accuracy over all of Switzerland is about 2 cm (± 1.1 cm).
With the FINELTRA CHENyx06, the regional deformations of the geodetic network can be
eliminated, the local deformations have to be eliminated by cadastral renewal projects.
