We have started to develop an integrated airborne survey system for three years from FY2003 to FY2005. In this system, we designed that the system could not only investigate underground structure but also survey water and temperature distribution for contributing disaster prediction. For these purposes, we will apply four geophysically different methods; the electromagnetics, the magnetics, the infrared images and the gamma-ray spectrometry in one survey and repeat this survey to monitor the underground structure and water and temperature distribution changes. In FY2003, a new electromagnetic survey system was designed and manufactured to investigate the underground structure to a depth of more than 300 m up to 1,000 m. Data acquisition and processing methods for the magnetics, the infrared images and the gamma-ray spectrometry were developed.
