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...
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...
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...
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...
Linear features determined from Landsat imagery in Wyoming
M. E. Cooley
1983, Open-File Report 83-935
This map is one of a series of linear-features maps compiled for the U.S. Geological Survey's Northern Great Plains Regional Aquifer System Analysis (U.S. Geological Survey, 1979).  This map shows the linear features that were recognized in Wyoming.  Other maps in the series cover South Dakota (Cooley, 1983a), Montana (Cooley,...
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,...
Estimating 1980 ground-water pumpage for irrigation on the High Plains in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
F.J. Heimes, R. R. Luckey
1983, Water-Resources Investigations Report 83-4123
Current ground-water use is required for the High Plains Regional Aquifer-System Analysis. In response to this need, a sampling approach was developed to estimate water pumped for irrigation on the High Plains during 1980. Pumpage was computed by combining application estimates with mapped irrigated-acreage information. Irrigation application (inches of water...
