20100030528 | Method, Apparatus, and System for Determining Accurate Location Data Related to Underground Installations - A system for determining location data related to at least one underground installation includes a non-invasive underground structure detection system, at least one analyzer mechanism, and at least one computer. The non-invasive underground structure detection system is configured to scan a survey area and transmit a first data set at least partially representative of the survey area. The survey area includes at least one underground installation. The at least one analyzer mechanism is configured to measure at least one physical characteristic associated with the at least one underground installation and transmit a second data set at least partially representative of the at least one measured physical characteristic. The at least one computer receives the first transmitted data and the second transmitted data, and determines location data related to the at least one underground installation based at least in part on the first and second transmitted data sets. | 02-04-2010 |
