Map showing vegetation distribution in the central part of the East Tintic Mountains, Utah Map showing vegetation distribution in the central part of the East Tintic Mountains, Utah
With the development of remote sensing technology has come the capability of defining and mapping plant communities by means of their spectral properties. Such maps will be an important aid in resource evaluation and management, especially in densely vegetated and remote areas of the world. This study in part of a broader program to determine the usefulness of multispectral scanner...
Maps showing aeromagnetic survey and geologic interpretation of the Chignik and Sutwik Island quadrangles, Alaska Maps showing aeromagnetic survey and geologic interpretation of the Chignik and Sutwik Island quadrangles, Alaska
An aeromagnetic survey over part of the Chignik and Sutwik Island quadrangles, on the southern Alaska Peninsula, was flown in 1977 as part of the Alaska mineral resource assessment program (AMRAP). Maps at scales 1:250,000 and 1:63,360 have been released on open-file (U.s. Geological Survey, 1978a, 1978b). This report includes the aeromagnetic map superimposed on the topographic base...
