Abstract
Underground Scanning Technology by Drone Electromagnetic Survey
The electromagnetic survey equipment, normally suspended with a helicopter, has recently been improved in Japan by downsizing and can be suspended with a drone. The electromagnetic drone survey was conducted for the first time in Singapore in November last year, and the resistivities in the ground at a depth of more than 100 m could be successfully measured to assume the geological conditions in the subsurface. This geophysical survey method has the potential to improve the quantity and quality of geophysical surveys. Even in areas that are difficult to access, geophysical surveys can be carried out quickly and easily by drone. Aerial electromagnetic surveys provide continuous three-dimensional digital data.
