Method and apparatus for displaying an excavation to plan
First Claim
1. A method for providing a display in real time of an excavation site having underground objects, including the steps of:
- determining a location of an earthworking machine in site coordinates;
determining a location of an earthworking implement relative to the earthworking machine, the earthworking implement being controllably mounted to the earthworking machine;
determining the location in site coordinates of at least one underground object at the excavation site and responsively inputting the location of the at least one underground object to a terrain map of the excavation site; and
displaying the terrain map including the location of the earthworking machine, the location of the earthworking implement, and the location of the at least one underground object in real time.

Abstract
A method and apparatus for providing a display in real time of an excavation site having underground objects. The method and apparatus includes determining a location of an earthworking machine in site coordinates, determining a location of an earthworking implement relative to the earthworking machine, determining the location in site coordinates of at least one underground object at the excavation site and responsively inputting the location of the at least one underground object to a terrain map of the excavation site, and displaying the terrain map including the location of the earthworking machine, the location of the earthworking implement, and the location of the at least one underground object in real time.

11. An apparatus for providing a display in real time of an excavation site having underground objects, comprising:
-
an earthworking machine having an earthworking implement controllably attached, the earthworking implement being adapted to perform excavation;
a position determining system located on the earthworking machine;
a terrain map of the excavation site;
means for determining the location in site coordinates of at least one underground object at the excavation site;
a controller adapted to receive a signal from the position determining system and responsively determine a position in site coordinates of the earthworking machine and the earthworking implement, to receive a signal indicating the location of the at least one underground object, and to provide a real time update to the terrain map of the terrain, and the locations of the earthworking machine, the earthworking implement, and the at least one underground object; and
a display adapted to receive a signal indicating the updated terrain map and to responsively display the location of the earthworking machine, the location of the earthworking implement, and the location of the at least one underground object. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
