Download or read book Evaluation of Aerial Remote Sensing Techniques for Defining Critical Geologic Features Pertinent to Tunnel Location and Design written by and published by . This book was released on 1976 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operational testing and evaluation of commercially available remote sensing data including space imagery, side-looking airborne radar, black-and-white, color infrared, color, and low sun angle photography. Multispectral scanner data (including thermal infrared), and airborne geophysical systems over the East River Mountain tunnel in West Virginia and the Carlin Canyon tunnel in Nevada demonstrates that, if integrated with conventionally acquired geologic data, remote sensing can reduce the cost of tunnel site selection and evaluation and in almost every instance provides unique geologic information.
