Water supply potential of the Lake Sally System, Marquette County, Michigan
Norman G. Grannemann
1978, Open-File Report 78-1046
Six lakes in the headwaters of Ely Creek form the Lake Sally system. This system is the source of water for Ishpeming and several small communities in the central part of Michigan's Upper Peninsula. During years of average precipitation, more water is used from the system than is supplied to...
Water resources data for Indiana, water year 1977
Water Resources Division, U.S. Geological Survey
1978, Water Data Report IN-77-1
Water resources data for the 1977 water year for Indiana consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels in wells. This report contains discharge records for 191 gaging stations; stage and contents for 12 lakes...
Water quality investigation of Francis Slocum Lake, Luzerne County, Pennsylvania
James L. Barker
1978, Open-File Report 78-819
This report summarizes water-quality data collected in the Francis Slocum Lake drainage basin, Pennsylvania, during an assessment from October 1976 to September 1977. Data were collected for nitrogen, phosphorus, carbon, and fecal coliform and fecal streptococcal bacteria.Results of the restricted sampling indicate that nutrient recycling within the lake is sufficient...
EROS Data Center Landsat digital enhancement techniques and imagery availability
Wayne G. Rohde, Jinn Kai Lo, Russell A. Pohl
1978, Canadian Journal of Remote Sensing (4) 63-76
The US Geological Survey's EROS Data Center (EDC) is experimenting with the production of digitally enhanced Landsat imagery. Advanced digital image processing techniques are used to perform geometric and radiometric corrections and to perform contrast and edge enhancements. The enhanced image product is produced from digitally preprocessed Landsat computer compatible...
Use of a remote computer terminal during field checking of Landsat digital maps
Charles J. Robinove, C.F. Hutchinson
1978, Journal of Research of the U.S. Geological Survey (6) 511-514
Field checking of small-scale land classification maps made digitally from Landsat data is facilitated by use of a remote portable teletypewriter terminal linked by teleplume to the IDIMS (Interactive Digital Image Manipulation System) at the EDC (EROS Data Center), Sioux Falls, S. Dak. When field checking of maps 20 miles...
The metallogenic role of east-west fracture zones in South America with regard to the motion of lithospheric plates (with an example from Brazil)
J. Kutina, William D. Carter, F.X. Lopez
1978, Jornal de Mineralogia (7) 97-110
The role of east-west fracture zones in South America is discussed with regard to global fracturing and the motion of lithospheric plates. A set of major NW-trending lineaments has been derived which show a tendency to be spaced equidistantly and may correspond to a set of east-west fractures in the...
Tectolinear interpretation of a 1:5,000,000 Landsat-1 mosaic compared with the structure of central and eastern United States
Jan Kutina, William D. Carter
1978, Global Tectonics and Metallogeny (1) 78-82
The pattern of lineaments and curvilinear features interpreted from a 1:5,000,000 mosaic of satellite images (Landsat-1 was superimposed on a simplified version of the Geological Map of the United States, 1:2,500,000 scale, showing the structural scheme of Central and Eastern United States. A comparison of the above two patterns, shown...
Hydrological applications of Landsat imagery used in the study of the 1973 Indus River flood, Pakistan
Morris Deutsch, F.H. Ruggles Jr.
1978, Journal of the American Water Resources Association (14) 261-274
During August and September 1973, the Indus River Valley of Pakistan experienced one of the largest floods on record, resulting in damages to homes, businesses, public works, and crops amounting to millions of rupees. Tremendous areas of lowlands were inundated along the Indus River and major tributaries. Landsat data made...
Flood damage assessment using computer-assisted analysis of color infrared photography
William H. Anderson
1978, Journal of Soil and Water Conservation (33) 283-286
Use of digitized aerial photographs for flood damage assessment in agriculture is new and largely untested. However, under flooding circumstances similar to the 1975 Red River Valley flood, computer-assisted techniques can be extremely useful, especially if detailed crop damage estimates are needed within a relatively short period of time.Airphoto interpretation...
