SHUTTLE IMAGING RADAR PROVIDES FRAMEWORK FOR SUBSURFACE GEOLOGIC EXPLORATION IN EGYPT AND SUDAN.
Carol S. Breed, John F. McCauley, Gerald G. Schaber
1984, Conference Paper
Shuttle Imaging Radar provides a pictorial framework to guide exploration for mineral resources (potential placers), groundwater sources, and prehistoric archaeological sites in the Western Desert of Egypt and Sudan. Documented penetration by the SIR-A signal of dry surficial sediment to depths of a meter or more revealed bedrock geologic features...
ANALYSIS AND REDUCTION OF LANDSAT DATA FOR USE IN A HIGH PLAINS GROUND-WATER FLOW MODEL.
Gail Thelin, Leonard Gaydas, Walter Donovan, Carol Mladinich
1984, Conference Paper
Data obtained from 59 Landsat scenes were used to estimate the areal extent of irrigated agriculture over the High Plains region of the United States for a ground-water flow model. This model provides information on current trends in the amount and distribution of water used for irrigation. The analysis and...
The relationship of Landsat digital data to the properties of Arizona rangelands
Emil H. Horvath, D. F. Post, J. B. Kelsey
1984, Soil Science Society of America Journal (48) 1331-1334
Pedon descriptions, vegetation transect information, and Landsat digital data were obtained for 110 sites on the Tonto National Forest in central Arizona. Using the field and satellite data, 33 variables were evaluated and prediction models were generated using stepwise multiple regression techniques. The following six factors explained 84% of the...
Alternate data sources for soil surveys on rangeland
Emil H. Horvath, A. A. Klingebiel, D. G. Moore, E. A. Fosnight
1983, Open-File Report 83-880
Soil information is an essential theme in a digital information base for land management and resource monitoring, but public land management agencies seldom have detailed soil maps available for all of the area under their administration. Most of these agencies conduct soil surveys on a scheduled basis, but escalating costs...
Linear features determined from Landsat imagery in North Dakota
M. E. Cooley
1983, Open-File Report 83-937
The report consists of a map (scale 1:500,000) that shows the linear features determined from Landsat imagery in North Dakota. The linear features, sometimes called linear trends or lineaments, are not identified as to type or origin. Most probably represent fractures or fracture zones, which may affect the movement of...
Use of digital land-cover data from the Landsat satellite in estimating streamflow characteristics in the Cumberland Plateau of Tennessee
E. F. Hollyday, G.R. Hansen
1983, Water-Resources Investigations Report 82-4059
Streamflow may be estimated with regression equations that relate streamflow characteristics to characteristics of the drainage basin. A statistical experiment was performed to compare the accuracy of equations using basin characteristics derived from maps and climatological records (control group equations) with the accuracy of equations using basin characteristics derived from...
Landsat analysis for uranium exploration in Northeast Turkey
Keenan Lee
1983, Open-File Report 83-99
No uranium deposits are known in the Trabzon, Turkey region, and consequently, exploration criteria have not been defined. Nonetheless, by analogy with uranium deposits studied elsewhere, exploration guides are suggested to include dense concentrations of linear features, lineaments -- especially with northwest trend, acidic plutonic rocks, and alteration indicated by...
General characteristics and availability of Landsat 3 and heat capacity mapping mission thermal infrared data
C. Scott Southworth
1983, Open-File Report 83-123
Two satellite systems launched by the National Aeronautics and Space Administration (NASA) in 1978 carried sensors which operated in the thermal infrared (IR) region of the electromagnetic spectrum, The final IR radiation data provide spectral information about the physical properties of the Earth's surficial materials not duplicated in either the...
Preliminary map of limonitic hydrothermal alteration for portions of the Needles 1° x 2° quadrangle, Arizona and California
Gary L. Raines
1983, Open-File Report 83-421
Portions of the Needles quadrangle have been designated by the Bureau of Land Management as potential wilderness areas and are being evaluated by a multidisciplinary team to determine the mineral-resource potential. As a part of this study Landsat images are being used to map the generalized distribution of limonitic materials...
The Alaska Mineral Resource Assessment Program: Guide to information contained in folio of geologic and mineral resource maps of the Philip Smith Mountains quadrangle, Alaska
H. N. Reiser, W. P. Brosge, T. D. Hamilton, D.A. Singer, W. D. Menzie II, K. J. Bird, J. W. Cady, J. R. Le Compte, J. B. Cathrall
1983, Circular 759
The geology and mineral resources of the Philip Smith Mountains quadrangle were virtually unexplored until the investigations for oil began in northern Alaska. Construction of the Trans-Alaskan Pipeline System has now made the quadrangle accessible by road. In 1975 and 1976 a team of geologists, geochemists, and geophysicists investigated the...
The Alaska Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Ambler River quadrangle, Alaska
Charles F. Mayfield, I.L. Tailleur, N. R. Albert, Inyo Ellersieck, Donald Grybeck, S. W. Hackett
1983, Circular 793
The Ambler River quadrangle, consisting of 14,290 km2 (5,520 mi2) in northwest Alaska, was investigated by an interdisciplinary research team for the purpose of assessing the mineral resource potential of the quadrangle. This report provides background information for a folio of maps on the geology, reconnaissance geochemistry, aeromagnetics, Landsat imagery,...
