M. D. Dettinger
1987, Water-Resources Investigations Report 87-4007
As a result of rapid urban growth in Las Vegas Valley, rates of water use and wastewater disposal have grown rapidly during the last 25 years. Concern has developed over the potential water quality effects of this growth. The deep percolation of wastewater and irrigation return flow (much of which...

Charles Berenbrock
1987, Open-File Report 86-315
Ground water is the sole source of water in Indian Wells Valley. Since 1966, annual ground-water pumpage has exceeded estimates of mean annual recharge, and continued and increased stresses on the aquifer system of the valley are expected. In 1981 the U.S. Geological Survey began a 10-year program to develop...

Methods and applications in surface depression analysis
Susan K. Jenson, Charles M. Trautwein
1987, Conference Paper, Auto-Carto VIII: Proceedings of the international symposium on computer-assisted cartography
Gridded surface data sets are often incorporated into digital data bases, but extracting information from the data sets requires specialized raster processing techniques different from those historically used on remotely sensed and thematic data. Frequently, the information desired of a gridded surface is directly related to the topologic peaks and...

J. Wright Horton, Jr., J. F. Sutter, T. W. Stern, D.J. Milton
1987, American Journal of Science (287) 635-660
Evidence of late Paleozoic (Alleghanian) penetrative deformation, amphilbolite-facies, metamorphism, and syntectonic granite emplacement has been found in an area of the central Piedmont in the southern Appalachians. The High Shoals Granite batholith in the Kings Mountain belt of south-central North Carolina consists of coarse-grained, megacrystic biotite granite with a strong,...
An algorithm for locating candidate labelling boxes within a polygon
Jan W. van Roessel
1987, Conference Paper, Auto-Carto VIII: Proceedings of the international symposium on computer-assisted cartography
Vector-based geographic information systems usually require annotation, such as a polygon number or attribute data, in a suitable location within a polygon. Traditional methods usually compute the polygon centroid, test the centroid for inclusion or exclusion, and select some alternative point when the centroid falls outside the polygon. Two problems...
Thermal maturity of tectonostratigraphic terranes within the Franciscan Complex, California
M.B. Underwood, M. Clark Blake Jr., D. G. Howell
E.C. Leitch, Erwin Scheibner, editor(s)
1987, Book chapter, Terrane Accretion and Orogenic Belts
Indicators of organic metamorphism provide valuable tools for analyzing the thermal history of tectonostratigraphic terranes. Paleotemperature estimates derived from vitrinite reflectance, for example, are more precise than values based upon inorganic mineral assemblages in low‐grade rocks. Isothermal geometries must be interpreted within the context of structural...

James D. Nichols, Holliday H. Obrecht III, James E. Hines
1987, Journal of Wildlife Management (51) 700-710
Banding and recovery data from American black ducks (Anas rubripes) and mallards (A. platyrhynchos) banded in the same breeding or wintering areas over the same time periods were used to estimate annual survival and band recovery rates. Recovery rates, based on preseason bandings, were very similar for sympatric black ducks...

1987, Journal of Geophysical Research B: Solid Earth (92) 10194-10206
Aeromagnetic data from surveys flown by the U.S. Geological Survey over Mount St. Helens, Washington, before and after the climactic May 18, 1980, eruption were used to determine the bulk magnetic properties of the volcano and to delineate a buried source. We assumed that most of the edifice of preeruption...

Image restoration techniques as applied to Landsat MSS and TM data
David Meyer
1987, Pecora XI Symposium 427-427
Two factors are primarily responsible for the loss of image sharpness in processing digital Landsat images. The first factor is inherent in the data because the sensor's optics and electronics, along with other sensor elements, blur and smear the data. Digital image restoration can be used to reduce...

Age-specificity of black-capped chickadee survival rates: Analysis of capture-recapture data
G. Loery, James D. Nichols, Kenneth H. Pollock, James E. Hines
1987, Ecology (68) 1038-1044
The ornithological literature indicates a widespread belief in two generalizations about the age—specificity of avian survival rates: (1) survival rates of young birds for some period following fledging are lower than those of adults, and (2) after reaching adulthood survival rates are constant for birds of all ages. There is...
Producing Alaska interim land cover maps from Landsat digital and ancillary data
Katherine Fitzpatrick-Lins, Eileen Flanagan Doughty, Mark Shasby, Thomas R. Loveland, Susan Benjamin
1987, Conference Paper, Pecora XI Symposium
In 1985, the U.S. Geological Survey initiated a research program to produce 1:250,000-scale land cover maps of Alaska using digital Landsat multispectral scanner data and ancillary data and to evaluate the potential of establishing a statewide land cover mapping program using this approach. The geometrically corrected and resampled Landsat...
Data integration using color space transforms
Jay W. Feuquay
1987, Pecora XI Symposium 326-326
The demand for increased spatial resolution without sacrificing spectral discrimination can be fulfilled by integration of data from different sensor systems and satellite programs. Data of high spatial resolution are frequently available in panchromatic (black-and-white) form rather than multispectral. Techniques gave been developed to combine the higher resolution...
Digital processing techniques and film density calibration for printing image data
Pat S. Chavez, Joseph A. McSweeney, Douglas R. Binnie
1987, Conference Paper, Pecora XI Symposium
Satellite image data that cover a wide range of environments are being used to make prints that represent a map type product. If a wide distribution of these products is desired, they are printed using lithographic rather than photographic procedures to reduce the cost per print. Problems are...
