Abstract
We describe a system for displaying buried utilities to the operator of an excavator. The display is based on 3D images of the subsurface obtained from advanced locating methods. As the excavator moves, the display changes so that it remains centered on the region near the bucket where the buried pipes are in danger of being broken.
