Method and apparatus for displaying an object at an earthworking site

A computer-based method for displaying a location of an object at an earthworking site, including the steps of:

• determining a location in geographical coordinates of an earthworking implement at the earthworking site;
• determining a location in geographical coordinates of the object;
• displaying the earthworking implement and the object on a display having a top view and a side profile view of the earthworking site;
• determining a region of uncertainty of the object as a function of at least one parameter;
• and
• enlarging the side profile view of the image of the object as a function of the region of uncertainty.

A computer-based method for displaying a location of an object at an earthworking site, including the steps of:

• determining a location in geographical coordinates of an earthworking implement at the earthworking site;
• determining a location in geographical coordinates of the object;
• displaying the earthworking implement and the object on a display having a top view and a side profile view of the earthworking site;
• selecting a perimeter of interest in the top view with respect to the earthworking implement;
• determining the coordinates of a portion of the object bounded by the perimeter of interest;
• displaying a three-dimensional image of the portion of the object in the side profile view as a function of the perimeter of interest;
• determining a region of uncertainty of the object as a function of at least one parameter;
• and
• enlarging the side profile view of the image of the object as a function of the region of uncertainty.

An apparatus for displaying a location of an object at an earthworking site, comprising:

• a position determining system adapted to determine a location of an earthworking implement at the earthworking site;
• means for determining a location of the object;
• a display having a top view and a side profile view of the earthworking site;
• means for selecting a perimeter of interest in the top view;
• and
• a processor adapted to determine a set of coordinates of a portion of the object within the perimeter of interest, display a three-dimensional image of the portion of the object in the side profile view, determine a region of uncertainty of the coordinates of the object, and enlarge the image of the object in the side profile view as a function of the region of uncertainty.
