1. An apparatus for determining the location of a digging implement at a work site, comprising:
- an undercarriage;
a car body rotatably connected to said undercarriage;
a receiver connected to said car body;
positioning system means for determining the location of said receiver in three dimensional space;
means for rotating said car body whereby said receiver moves through an arc, said positioning system means determining the location of said receiver at a plurality of points along said arc; and
a processing means for determining the location of said car body in response to the location of said plurality of points.
