In order to fundamentally solve the problem of inaccurate cadastral information across the country, our country has promoted the reinvestigation, remeasurement and re-registration of cadastral information with the object of the homeland. The existing cadastral information has changed a lot as the reinvestigation of cadastre was proceeding. Hence, the attention has also been concentrated at the interior and underground space of the building except for the land surface. However,the practical situation is that the research about of the underground space position determination is not enough.

In this research, the possibility and validity of the 3D underground space position determination application by using MEMS INS and air pressure sensor for the underground space as tunnel and underground floors has been discussed. Through this research, the possibility of the position determination and underground space position service depended on the underground space construction process has been confirmed.

The verification results of accuracy of 3D position determination technique on the ground/underground and the practicability in the underground space are as follows: The accuracy of the horizontal position in the long tunnel can be obtained around 10 m.The accuracy of the vertical position (scale height) of the construction’s interformational division can be obtained around 4 m. The result of performance has identified the practical possibility in plenty of underground places such as underground parking garages.
