METHODS AND SYSTEMS FOR LAND SURVEYING

Disclosed herein is a computerized method for land surveying. The method includes a calibration stage and a land surveying stage. The calibration stage includes: placing a total station (TS) at an origin; selecting at least three reference positions, each having good satellite reception and being at a line-of-sight from the TS; using an antenna(s) to obtain satellite coordinates of the reference positions; using the TS to obtain coordinates, relative thereto, of the reference positions; determining absolute coordinates of the origin, based on the obtained satellite coordinates and the coordinates relative to the TS. If the absolute coordinates of the origin are not determined to a required precision, repeating the calibration stage taking into account an additional reference position(s). Else, continuing to the land surveying stage, wherein the TS is used to measure coordinates, relative to the TS of locations in a surveyed area, thereby obtaining absolute coordinates of the locations.
