According to a field support system for spatial information on roads and ground facilities using an NFC tag according to the present invention, a location information providing device including an NFC tag can expand and contract according to buried depth by having multi-stage structure. As a result, the signal recognition rate of a NFC tag can be improved, and backfilling and layer compaction can be easily performed during underground facility construction. Also, the signal recognition rate of an NFC tag can be significantly improved by providing, by the location information providing device, a leveling function to an NFC tag to be leveled even though an underground environment changes. The field support system for spatial information on roads and ground facilities using an NFC tag comprises: a ground indicator which is installed at multiple spots on the ground, and stores information on an underground facility buried nearby; a location information providing device which is mounted on the top of the underground facility buried at a location corresponding to the ground indicator, and provides the spatial information on the underground facility using an NFC tag; a user terminal which has an NFC reader, receives the spatial information on the underground facility transmitted by the NFC tag from the location information providing device when the user terminal approaches the ground indicator, and transmits the information over a communication network; and a location information server which receives an encoding code including the spatial information on the underground facility from the user terminal, decodes the spatial information on the underground facility, and transmits the decoded information to the user terminal or stores the decoded information. |
