Urban and regional land use change detected by using Landsat data
William J. Todd
1977, Journal of Research of the U.S. Geological Survey (5) 529-534
The Atlanta Regional Commission and the Earth Resources Observation Systems Data Center participated in a demonstration of the use of Landsat digital data to detect land use change in the Atlanta, Ga., area. Temporal overlays combining Landsat band-5 data from October 1972 and 1974 were made by using the General...
A radiometric interpretive legend for Landsat digital thematic maps
Charles J. Robinove
1977, Photogrammetric Engineering and Remote Sensing (43) 593-594
A legend is suggested for use with computer-generated thematic maps made from Landsat digital data that designates some of the radiometric characteristics of each thematic map unit as well as the described terrain attributes of each map unit. The relationship between spectral band and radiance for each map unit is...
Landsat data availability from the EROS Data Center and status of future plans
Russell A. Pohl, G.G. Metz
1977, Conference Paper, OCEANS '77 Conference Record
The Department of Interior's EROS Data Center, managed by the U.S. Geological Survey, was established in 1972, in Sioux Falls, South Dakota, to serve as a principal dissemination facility for Landsat and other remotely Sensed data. Through the middle of 1977, the Center has supplied approximately 1.7 million copies of...
Structure mapping on enhanced landsat images of Southern Brazil: Tectonic control of mineralization and speculations on metallogeny
Terry W. Offield, E.A. Abbott, A. R Gillespie, S.O. Loguercio
1977, Geophysics (42) 482-500
Computer enhancement, particularly contrast-stretching, reveals a previously unnoticed east-west structural zone across a Landsat image of the southern Brazilian Precambrian shield. In this zone occur the only known economic or near-economic deposits of gold, tin, and copper. Such deposits are typically localized by small east-west structural elements. Non-economic copper occurrences...
Discrimination of hydrothermal altered and unaltered rocks in visible and near infrared multispectral images
L. C. Rowan, A. F. H. Goetz, Roger P. Ashley
1977, Geophysics (42) 522-535
Mineralogical differences between altered rocks and most unaltered rocks in south-central Nevada cause visible and near-infrared (0.45 to 2.4 mu m) spectral-reflectance differences which can be used to discriminate these broad categories of rocks in multispectral images. The most important mineralogical differences are the increased abundance of goethite, hematite, and...
Mapping of hydrothermal alteration in the Cuprite mining district, Nevada, using aircraft scanner images for the spectral region 0.46 to 2.36µm
M. J. Adams, Roger P. Ashley, L. C. Rowan, A. F. H. Goetz, A.B. Kahle
1977, Geology (5) 713-718
Color composites of Landsat Multispectral Scanner ratio images that display variations in the intensity of ferric-iron absorption bands are highly effective for mapping limonitic altered rocks but are ineffective for mapping nonlimonitic altered rocks. Analysis of 0.45- to 2.5-µm field and laboratory spectra shows that iron-deficient opalized rocks in the...
A selected bibliography: Application of Landsat digital multispectral scanner data to agriculture, forestry, and range management
Wayne G. Rohde
1977, Report
This bibliography contains citations of selected publications and technical reports dealing with the application of Landsat digital data analysis techniques to agriculture, forestry, and range management problems. All of the citations were published between 1973 and 1977. The citations reference publications and reports which discuss specific analysis techniques and specific...
Electronic thermal sensor and Data Collection Platform technology: Part 5 in Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System
Duane M. Preble, Jules D. Friedman, David Frank
1976, Report, Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System
Five Data Collection Platforms (DCP) were integrated electronically with thermall sensing systems, emplaced and operated in an analog mode at selected thermally significant volcanic and geothermal sites. The DCP's transmitted 3260 messages comprising 26,080 ambient, surface, and near-surface temperature records at an accuracy of ±1.15 °C for 1121 instrument days...
Exploration for porphyry copper deposits in Pakistan using digital processing of Landsat-1 data
Robert G. Schmidt
1976, Journal of Research of the U.S. Geological Survey (4) 27-34
Rock-type classification by digital-computer processing of Landsat-1 (formerly ERTS-1) multispectral scanner data has been used to select 23 prospecting targets in the Chagai District, Pakistan, 5 of which have proved to be large areas of hydrothermally altered porphyry containing pyrite. The known porphyry copper deposit at Saindak was used as...
Monitoring arctic habitat and goose production by satellite imagery
H.M. Reeves, F.G. Cooch, R. E. Munro
1976, Journal of Wildlife Management (40) 532-541
Spacecraft imagery, especially from the National Atmospheric and Oceanic Administration's Improved TIROS (Television Infra-Red Observational Satellite) Operational Satellites, permits timely evaluations of snow and ice conditions encountered by arctic nesting geese. Imagery from the TIROS satellite for 5 wide]y scattered locations in arctic North America was obtained for three...
Mapping and measuring land-cover characteristics of New River Basin, Tennessee, using Landsat digital tapes
E. F. Hollyday, S.P. Sauer
1976, Water-Resources Investigations Report 76-106
Land-cover information is needed to select subbasins within the New River basin, Tennessee, for the study of hydrologic processes and also is needed to transfer study results to other sites affected by coal mining. It was believed that data recorded by the first Earth Resources Technology Satellite (Landsat-1) could be...
