Assessing mesquite-grass vegetation condition from Landsat
Kirk C. McDaniel, Robert H. Haas
1982, Photogrammetric Engineering and Remote Sensing (48) 441-450
Landsat multispectral scanner (MSS) band values, band ratios, and vegetation index models were compared with selected rangeland vegetation parameters collected at six test sites within the honey mesquitellotebushlmixed grass association in north-central Texas. The comparisons at four dates showed that two vegetation index models, TV16 and GVI, are highly correlated...
Landsat classification accuracy assessment procedures
R. R. Mead, John Szajgin
1982, Photogrammetric Engineering and Remote Sensing (48) 139-141
A working conference was held in Sioux Falls, South Dakota, 12-14 November, 1980 dealing with Landsat classification Accuracy Assessment Procedures. Thirteen formal presentations were made on three general topics: (1) sampling procedures, (2) statistical analysis techniques, and (3) examples of projects which included accuracy assessment and the associated costs, logistical...
Oahu: perspective from space
Gary E. Johnson
1982, Journal of Geography (81) 30-32
Satellite remote sensing provides us with a unique perspective from space. This perspective is synoptic in nature and provides regional views of most of the land areas of the earth. The orbital characteristics of the Landsat system are such that repetitive imagery of the same area may be obtained. Because...
Space platform albedo measurements as indicators of change in arid lands
C.J. Robinove
1982, Advances in Space Research (2) 31-35
The change in albedo of arid lands is an indicator of changes in their condition and quality, including density of vegetative cover, erosion, deposition, surficial soil moisture, and man-made change. In general, darkening of an arid land surface indicates an increase in land quality while brightening indicates a decrease in...
Landsat monitoring of desert vegetation growth, 1972-1979 using a plant-shadowing model
Joseph Otterman, C.J. Robinove
1982, Advances in Space Research (2) 45-50
Landsat digital data spanning the period 1972-1979 were analyzed to monitor the status of vegetation within and outside an exclosure in the northern Sinai (precipitation 100-150 mm/year). This 6??6 km exclosure was fenced off in the summer of 1974 and subsequently has been free from the anthropogenic pressures (overgrazing, cultivation...
Applications of Landsat imagery to problems of petroleum exploration in Qaidam Basin, China
G. B. Bailey, P. D. Anderson
1982, American Association of Petroleum Geologists Bulletin (66) 1348-1354
Tertiary and Quaternary nonmarine, petroleum-bearing sedimentary rocks in the Qaidam basin of remote western China have been extensively deformed by compressive forces. These forces created many folds which are current targets of Chinese exploration programs. Manual techniques of image analysis and interpretation were applied to computer-enhanced Landsat images of the...
Computation with physical values from Landsat digital data
C.J. Robinove
1982, Photogrammetric Engineering and Remote Sensing (48) 781-784
Landsat digital images are commonly analyzed by using the digital numbers for each pixel recorded on a computer-compatible magnetic tape. Although this procedure may be satisfactory when only a single, internally consistent image is used, the procedure may produce incorrect results if more than one image is used for analysis...
Evaluation of 0.46- to 2.36-mu m multispectral scanner images of the east Tintic mining district, Utah, for mapping hydrothermally altered rocks
L. C. Rowan, A.B. Kahle
1982, Economic Geology (77) 441-452
Airborne multispectral scanner images recorded in the 0.46- to 2.36-mu m region for the East Tintic mining district, Utah, were evaluated to determine their usefulness for distinguishing six types of hydrothermally altered rocks from a wide range of sedimentary and igneous rock types. Limestone, dolomite, and argillaceous rocks were of...
A relation between landsat digital numbers, surface reflectance, and the cosine of the solar zenith angle
William S. Kowalik, Stuart E. Marsh, Ronald J. P. Lyon
1982, Remote Sensing of Environment (12) 39-55
A method for estimating the reflectance of ground sites from satellite radiance data is proposed and tested. The method uses the known ground reflectance from several sites and satellite data gathered over a wide range of solar zenith angles. The method was tested on each of 10 different Landsat images...
Implications of the Precambrian lineaments on the Red Sea tectonics based on Landsat study of northeast Sudan
F. Ahmed
1982, Global Tectonics and Metallogeny (1) 326-335
Lineament analysis of a Landsat Imagery mosaic (scale 1:1,000,000) of northeast Sugdan indicate significant curvilinear as well as rectilinear fracture patterns of possible Precambrian age.  Rectilinear features trend dominantly in N-S (± 10°), NNW and ENE, and less commonly in NW and EW directions.  The Precambrian fractures closely match, and...
Use of Landsat data to evaluate lesser prairie chicken habitats in western Oklahoma
R. W. Cannon, Fritz L. Knopf, Lawrence R. Pettinger
1982, Photogrammetric Engineering and Remote Sensing (46) 915-922
Landsat digital data were used to evaluate lesser prairie chicken (Tympanuchus pallidicinctus) habitats in western Oklahoma. Data for 7 (4,144 ha) study areas, 4 in shinnery oak (Quercus havardii), and 3 in sand sagebrush (Artemisia filifolia) rangeland, were analyzed using the Interactive Digital Image Manipulation System at the EROS Center....
Evaluation of AMOEBA: a spectral-spatial classification method
Susan K. Jenson, Thomas R. Loveland, J. Bryant
1982, Journal of Applied Photographic Engineering (8) 159-162
Muitispectral remotely sensed images have been treated as arbitrary multivariate spectral data for purposes of clustering and classifying. However, the spatial properties of image data can also be exploited. AMOEBA is a clustering and classification method that is based on a spatially derived model for image data. In an evaluation...
