DTIC AD0748663: Tunnel-Site Selection by Remote Sensing Techniques

A study of the role of remote sensing for geologic reconnaissance for tunnel-site selection was commenced. For this study, remote sensing was defined as ultraviolet to thermal infrared multispectral scanning, X- and L-band synthetic aperture radar, and aerial photography. Data from these sensors were processed and evaluated in terms of their complementary use. This report can be used tutorially on the data processing and basic instrumentation of conventional remote sensing. Future research directions are suggested, and the extension of remote sensing to include airborne passive microwave sensor systems, magnetometry, gamma-ray sensors, gravimetry, and airborne electromagnetic sounding systems is discussed.
