Remote Sensing of Earth Resources (1970-1973 Supplement): A Literature Survey with Indexes
This literature survey cites 4930 reports, articles and other documents that were announced between March 1970 and December 1973 in Scientific and Technical Aerospace Reports (STAR) or in International Aerospace Abstracts (IAA). This publication supplements Remote Sensing of Earth Resources (NASA-SP-7036) that cited documents announced between January 1962 and February 1970. Beginning in 1974, a quarterly publication, Earth Resources, A Continuing Bibliography (NASA-SP-7041) was initiated. The first issue, NASA-SP-7041(01), was published in June covering the document announced between January 1974 and March 1974. The coverage includes documents related to the identification and evaluation by means of sensors in spacecraft and aircraft of vegetation, minerals, and other natural resources, and the techniques and potentialities of surveying and keeping up-to-date inventories of such riches. It encompasses studies of such natural phenomena as earthquakes, volcanoes, ocean currents and magnetic fields; and such cultural phenomena as cities, transportation networks, and irrigation systems. Descriptions of the components and use of remote sensing and geophysical instrumentation, their subsystems, observational procedures, signature and analyses and interpretive techniques for gathering data are also included. Reports generated under NASA's Earth Resources Survey Program and announced during the period covered by this bibliography are included.
