Consulting / Analyses

As a provider of consulting services, swisstopo is able to offer support both at home and abroad with the planning and optimisation of geodata network installations, the planning and evaluation of GNSS survey campaigns, the calculation of spatially-related geo-potential models, deformation analyses and the transformation of coordinates.

Deformation monitoring of a dam
Deformation monitoring of a dam

These services are offered for the following topics:

  • Coordinate transformation between different reference systems (i.e. between the local Swiss reference systems CH1903 and CH1903+ and the global reference systems ETRS89, CHTRS95, ITRS89 or WGS84, and vice-versa)
  • Three-dimensional computations with geopotential models: geoid (geoid-ellipsoid separation, deviations from the vertical), quasi-geoid (geoid anomalies), gravity (normal gravity, interpolated gravity), etc.
  • Computation of rigorous heights, e.g. orthometric and normal heights from geopotential numbers
  • Project planning and adjustment of geodetic networks (triangulation, levelling and GNSS)
  • Planning GNSS observations, which includes the determination of satellite visibility and the computation of visibility on the ground, and processing the observations with GNSS software
  • Deformation analysis based on repeated geodetic observations
  • Transformations and interpolations of coordinates and heights in existing constrained reference frames (LV03, LN02, etc.)
