Illinois Geology From Space (Classic Reprint)

Excerpt from Illinois Geology From Space Geologists have largely made use of these new data in the way that they have been accustomed to using aerial photographs. The synoptic views provided by the small – scale, uniformly illuminated views are valuable for surficial geo logic mapping. A single scene covers a wide variety of terrain, geology, and land-use types, and is presented under nearly Optimum viewing conditions that emphasize the contextural relations of surface features. Enhancement by com puter processing and photographic techniques has been used to get more information from data from space platforms. The purpose of this paper is to review the availability of erts images and Skylab and high – altitude aircraft photographs of Illinois and to discuss their use and value to the geologist. These images and photographs are also of great value to soil scientists, agricultural experts, foresters, engineers, cartographers, local and regional planners, limnologists, hydrologists, highway planners, and others. General reviews of the value of erts images to these and other specialists can be found in publications by nasa-goddard Space Flight Center (finch, 1972; Freden, Mercanti, and Becker, 1973; Freden, Mercanti, and Witten, 1973; Freden and Mercanti, 1973; Freden, Mercanti, and Friedman, l97ha, l97hb; Freden, Mercanti, and Becker, 197a), the American Society of Photogrammetry and Anson A useful review of geological applications of erts and Skylab data is available in Short and Lowman 3 earth resources technology satellite (erts) The first of two preposed erts satellites was launched into a polar rbit on July 23, 1972. Since then, more than photograph-like images overing more than 80 percent of the earth’s land surface have been returned.
