1979, Open-File Report 79-960
The Virginia Range, immediately southeast of Reno, Nev., consists mainly of flows, breccias, and turfs of Miocene age. Most of these volcanic rocks are of intermediate composition; rhyodacite is the most common rock type. Basalt, rhyolite and rhyolite tuff, and tuffaceous sedimentary rocks of Miocene and Pliocene age also cover...

In the past several years, earthquake research has been greatly accelerated in China, Japan, USSR, and the United States. Presently, about 2,500 earthquake-related publications (including meeting abstracts) are produced yearly. In order to keep up with this current literature, a computer based bibliographic system was implemented as part of a...

1979, Open-File Report 79-1466
A detailed stratigraphic and geochemical program was conducted in 1978 on the strata of the upper phosphatic mudstone member of the Santa Margarita Formation at Newsome Canyon, Santa Barbara County, California, (fig 1). This program was undertaken to determine the phosphate content of each stratigraphic unit in an area of...
Surveying Antarctica: from dogsled to satellite
Richard S. Williams Jr.
1979, Air and Space (3) 3-4
Base maps of Antarctica are needed at scales of 1:250,000 to plot scientific data, yet after 20 years of a major mapping effort, only about 20 percent of the continent has been accurately mapped using aerial photographs and ground surveys. Encompassing nearly 14.3 million square kilometers (5.5 million square miles),...
Satellite-aided evaluation of population exposure to air pollution

1979, Environmental Science & Technology (13) 970-974
The Clean Air Act Amendments of 1977 set schedules for states to implement regional, spatial assessments of air quality impacts. Accordingly, the U.S. Environmental Protection Agency recently published guidelines for quantifying population exposure to adverse air quality impact by using air quality and population data by census tracts. Our research...
Satellites monitor Atlanta regional development

1979, Practicing Planner (9) 6-10
Since the adoption of a Regional Development Plan in 1975, the Atlanta Regional Commission has investigated methods for monitoring regional development patterns in a periodic, efficient manner. A promising approach appears to be the use of Landsat satellite data. In cooperation with the Earth Resources Observation Systems (EROS) Data Center,...
Inventory and mapping of flood inundation using interactive digital image analysis techniques
Wayne G. Rohde, Charles A. Nelson, J. V. Taranik
1979, Canadian Journal of Remote Sensing (5) 43-52
LANDSAT digital data and color infra-red photographs were used in a multiphase sampling scheme to estimate the area of agricultural land affected by a flood. The LANDSAT data were classified with a maximum likelihood algorithm. Stratification of the LANDSAT data, prior to classification, greatly reduced misclassification errors. The classification results...
