DTIC AD0734028: Tunnel-Site Selection by Remote Sensing Techniques

An investigation designed to utilize simultaneously aerial photographs, microwave radar, and multispectral scanners for geologic studies was commenced. In conjunction with ground-truth investigations, the authors used aerial photographs and data acquired from both passive multispectral scanning and multispectral, multipolar, microwave radar systems in the attempt to construct geologic and lithological maps applicable to the selection of tunnel sites.
