Survey Computations for PC
A powerful and comprehensive suite of programmes for the manipulation of complex formulae for the survey world.
New Hydro version available
includes “Law of the Sea” option
Provides a simple quick means to:
Manipulate complex formulae on a variety of ellipsoids, grids and projections to:
Convert co-ordinates from grid to geographic to cartesian values.
Compute parameters to change from one geodetic datum to another and perform the change.
Compute conformal or non-conformal parameters to change fromone grid to another and perform the change.
Reduce terrestrial observations to the ellipsoid and grid.
Compute co-ordinates by triangle, traverse, resection and intersection.
Compute level networks and height determinations by least squares.
Compute co-ordinates by a variation of co-ordinates using the principle of weighted least squares with a full analysis of the results.
Compute pre-observation analysis of terrestrial and GPS networks.
Determine astronomic azimuth and right ascension and declination from the azimuth and altitude of the stars.
Determine spheroid azimuth and ellipsoid distance from latitude and longitude.
Determine latitude and longitude from ellipsoid azimuth and distance.
Determine grid bearing and distance.
Compute gravity earth tide corrections.
Interpolate geoid / ellipsoid separation using the Earth Geoid Model 1996 and DoD multiple regression equations.
Compute velocity updates for the GPS Fiducial stations.
Compute the least squares solution of Ax = b + v.
New! An online Calculator containing a fully comprehensive range of specialised survey functions is now available with all versions.
