3D Utility Mapping Using Integrated Geophysical Technologies

This paper provides a conceptual overview of the field data collection process and briefly discusses how geophysical data, georeferenced to map coordinates, are merged through the processing, analysis and interpretation stages into an on-screen format. Within this merged format, the processed and properly position-referenced geophysical data are overlaid and viewed in a selectable fashion, together or alone in any combination with georeferenced maps, CAD drawings, aerial photos or other suitable information.
