Geological questions and significant results provided by early ERTS-1 data

There are no author-identified significant results in this report. The organization for evaluating the uses of Earth Resources Technology Satellite data of the United States and foreign areas is described. The implementation of a system to disseminate the data to the geographical areas of interest is discussed. Brief descriptions are included of data received for the following areas: (1) east coast, (2) central United States, (3) western mountain areas, (4) west coast areas, and (5) Alaska. It is concluded that the multiband approach is useful with each of the bands providing unique and useful information. The difficulties in handling the data if all seven bands are used are examined.

A first look at geological aspects of ERTS imagery of Wyoming

There are no author-identified significant results in this report. The analysis of six MSS-5 frames covering most of the western half of Wyoming is discussed. The frames under consideration covered the following areas: (1) Rock Springs, (2) Western Wind River Basin, and (3) Bighorn Basin-Absarokas Mountains. Miscellaneous observations concerning identification of natural and man-made structures are included.

A first-look machine analysis of ERTS-1 data

There are no author-identified significant results in this report. The preliminary analysis of a black and white image of channel 5 data together with tapes from the multispectral scanner is discussed. Four sub-projects based on the initial analysis are discussed. The sub-projects are the analysis by multispectral pattern recognition techniques of the full frame and two particular subframes and a study of the data quality. The procedures for conducting the study and the limitations in analyzing the data are examined. Methods for improving the analysis of the frames by first and second iteration are presented.
