Analysis of Position for Underground Facility Using GPS

The complex facilities on the ground have begun to be laid under the ground as increasing emphasis on the beauty of Cities due to centralization. But, as the kind of the facilities have been concentrated on the narrow area, accidents occur due to the difficulty of maintenance and the inaccuracy of data. In this study, for the evaluation of exact depth using the electro-magnetic induction method and GPR(Ground Penetration Radat) m city area, the practicability of the underground probing, field test IS proved to be excellent by experimentally. It was acqwred the position information for the underground facilities using a RTK-GPS. As the result, we have analyzed the accurate position of the underground facility and show the way uuproving accuracy in detecting and surveying comparing with the tradttional surveying method Also, we hope to contnbute the effective maintenance and the prevention of disasters to the underground facility.
