For the needs of Geodesy and Land Surveying swisstopo produces or procures software and constantly improves and maintains it since a long time. The programs cover all areas of traditional surveying, geodesy and GPS positioning.
CHGEO2004 DLL
Swiss geoid model for REFRAME DLL,
REFRAME FME Plug-in or third-party products
The current geoid model of Switzerland, CHGeo2004, allows to transform ellipsoidal heights (Bessel) to orthometric heights (LHN95) and vice versa.
GEOREF
Change between reference systems and
map projections for the exchange and the migration of data of different origin
Software to transform between reference systems and map projections for the exchange and migration of data from different origins.
KOORDIFF
Calculation and representation
of coordinate differences
Program for calculation and display of coordinate differences in point fields, especially for the analysis of deformation measurements, the comparison of LTOP calculation variants or the analysis of residuals after transformations.
LTOP
Adjustment of geodetic networks
Pre-analysis and adjustment software for polygon networks, triangulation networks, combinations of GNSS observations and terrestrial measurements as well as leveling networks.
PLANETZ
Graphic representation of networks
Software for the graphical presentation of surveying network plans and results of network compensation with LTOP.
REFRAME
Planimetric and/or altimetric reference frame
change (GPSRef + Fineltra + CHGeo + Htrans + TransILI)
Software for the transition of reference frames in position and/or height for applications in the Swiss national survey and in the cadastral survey with highest accuracy requirements.
TRANSINT
Transformation and interpolation of points
Software for planimetric transformation and interpolation of points that allows the comparison of geodetic networks or adjustments with existing fixed points.
