ABSTRACT:
A method and apparatus for determining an offset path from an actual path using a mobile surveying device. In one embodiment, a sequence of continuous measured points is generated using a satellite positioning system included with the disclosed mobile surveying device. Offset points are computed relative to the measured points using half angle calculations. Each offset point is computed relative to the middle point of three continuous measured points generated by the satellite positioning system along the actual path. The offset points are continuously generated with the mobile surveying device in real time and in the field.
