The Global Positioning System, with its capability for both precisely positioning and navigating an aircraft, has created new scientific opportunities for studying the earth. This book examines the state of the art in airborne geophysics as integrated with new precise positioning systems, and it outlines the scientific goals of focused effort in airborne geophysics, including advances in our understanding of solid earth processes, global climate change, the environment, and resources.

This volume includes papers from around the world, including China and the Soviet Union, and besides the papers on exploration techniques and case histories there are sections on the use of remote sensing in logistical planning, hydrogeology and in studies of the environment aspects of mining operations. Gold exploration receives special attention and there is considerable emphasis on the integration of remotely sensed imagery with other data sets in geographic information systems. Advances in high spectral resolution remote sensing, particularly in China and the United States are presented in a series of papers.

As a slag heap, the result of strip mining, creeps closer to his house in the Ohio hills, fifteen-year-old M. C. is torn between trying to get his family away and fighting for the home they love.
