AERIAL PHOTOGRAPHY IN ENGINEERING GEOLOGY. ENGINEERING GEOLOGY IN PRACTICE IN BRITAIN: 8

The relation is reviewed of the needs and effects of construction to the conditions and limitations presented by the natural environment. The intrepretation of aerial photographs requires the application of dual expertise: a thorough understanding of land surface structure and development, petrology, sedimentary, physical, structural, stratigraphical and hydro-geology; and knowledge of civil engineering requirements, design, limitations, economics, and construction techniques. The proper use of serial photography involves the correct selection of the right film media, the use of the appropriate geometrical controls, scale, angle etc. and intelligent timing. Criteria related to each of these factors are discussed. Characteristics of panchomatic (its' value is in its tonal and textural exactness), infrared black and white, infrared false color, and multispectrual photography are discussed. Reflectivity of the ground, and the medium of reproduction of the photo image are also considered. Three major ways of viewing photographs are described as well as image enhancement techniques. Various interpretation techniques are outlined, and comments are made on various other types of remote sensing techniques.
