ABSTRACT:
An integrated earth contouring system uses a postioning system such as a GPS system to track the location of an earthmover on a work site. A display device visible to a driver of the earthmover displays a difference between an existing surface contour and a desired surface contour of the work site. The display device may show a three-dimensional image which rotates or a two-dimensional image having a cursor which rotates to represent the earthmover. A blade sensor tracks the position of the earthmover blade, and the display is updated to show changes in the existing surface contour when the earthmover is moved on the site with the blade height between the height of the existing surface and the height of the desired surface. An orientation sensor on board the earthmover provides the microprocessor with the orientation of the earthmover, and a memory unit is provided to allow storage and retrieval of surface data by the microprocessor. The system can integrate the tracking of earthmover activity and surface development, as well as a utility line avoidance feature and a hydrology analysis function.
