Questions and answers

Q: What is the reduction distance of length taken into the account in the program, is it possible to take into account atmospheric corrections (for example temperature, pressure), geometric and projection corrections. Is it possible to choose its zero level of length reduction?

A: Atmospheric corrections are supposed to be done by the instrument. Geometric and projection corrections can be set as PPM (mm/km) in the Calculation parameters dialogue. GeoEasy is mainly used for engineering surveying, and the default value for geometric and projection correction is 0.

Q: How do we calculate the difference in height difference with geometric levelling technology (correction of the partition, consideration of the temperatures and taking into account the calibration report of the levelling staff).

A: GeoEasy cannot take into consideration the calibration of levelling staff and temperature. You should input the corrected height difference. It can read GSI files from DNA03 instrument, but no calibration data can be considered.

Q: Is it possible that a horizontal geodetic network can be offset as a free net, where all coordinates of points represent approximate values.

A: Yes, do not specify any given points. In the adjustment result if the "Network defect" is not zero then free network adjustment were made and all coordinate changes are considered in the minimum condition.
