An assessment of Landsat data acquisition history on identification and area estimation of corn and soybeans
M. M. Hixson, M. E. Bauer, Donna K. Scholz
1982, Remote Sensing of Environment (12) 123-128
In the past decade, numerous studies have demonstrated the potential of satellite remote sensing for providing accurate timely crop area information. This study assessed the impact of Landsat data acquisition history on classification and area estimation accuracy of corn and soybeans in the U.S. Corn Belt. The results illustrate the...
Characterization of tropospheric desert aerosols at solar wavelengths by multispectral radiometry from Landsat
Joseph Otterman, R. S. Fraser, O. P. Bahethi
1982, Journal of Geophysical Research C: Oceans (87) 1270-1278
Characteristics of tropospheric desert aerosols are derived by comparing nadir spectral reflectivities computed from the radiative transfer models with reflectivities measured from Landsat. Over the ocean, reflectivities are compared, but over land the comparison is carried out by determining the ratios of the nadir reflectivity of the surface-atmosphere system over...
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
Richard 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....
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...
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...
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...
Assessment of impacts of proposed coal-resource and related economic development on water resources, Yampa River basin, Colorado and Wyoming: A summary
Timothy Doak Steele, Donald E. Hillier
1981, Circular 839
Expanded mining and use of coal resources in the Rocky Mountain region of the western United States will have substantial impacts on water resources, environmental amenities, and social and economic conditions. The U.S. Geological Survey has completed a 3-year assessment of the Yampa River basin, Colorado and Wyoming, where increased...
