    A statistical evaluation of the advantages of Landsat Thematic Mapper data in comparison to Multispectral Scanner data (1984)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: On July 16, 1982, the second decade of land remote sensing from space was inaugurated with the successful launch of Landsat-4. This satellite carries the Multispectral Scanner (MSS) and a new sensor, the Thematic Mapper (TM). The TM represents the result of an effort in which all of the major improvements in remote-sensing capability were simultaneously integrated into one system. An experiment was developed and conducted to quantify the effect of each TM sensor parameter on classification accuracy. This paper discusses the experimental design and summarizes the results obtained using TM data acquired over the Washington, DC area on November 2, 1982. Attention is given to a study site/data description, the experimental design, photointerpretation and digitization, spectral simulation, radiometric simulation, and spatial simulation.

    The 3D inelastic analysis methods for hot section components (1984)
    In:  CASI
    Details
    Publication Date: 2016-06-07
    Description: Advanced 3-D inelastic structural/stress analysis methods and solution strategies for more accurate and yet more cost-effective analysis of combustors, turbine blades, and vanes are being developed. The approach is to develop four different theories, one linear and three higher order with increasing complexities including embedded singularities. Progress in each area is reported.

    Measurements of plasma, plasma waves, and suprathermal charged particles in Saturn's inner magnetosphere (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The Pioneer 11 and Voyager 1, 2 traversals of Saturn's inner magnetosphere provided direct information on the complex and highly structured distributions of plasma and suprathermal charged particles present in this region. The Voyager wave intruments also yielded absolute electron density measurements in certain inner magnetosphere locations; the wave data were used to evaluate the magnitudes of several wave-particle interactions. The plasma and wave measurements for 24-hr periods centered around closest approach, are summarized, pitch-angle scattering effects possibly associated wtih measured whistler mode turbulence are evaluated, and the effects of wave-particle interactions associated with electrostatic waves are discussed.

    Lunar magnetism (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Aspects of lunar paleomagnetic and electromagnetic sounding results which appear inconsistent with the hypothesis that an ancient core dynamo was the dominant source of the observed crustal magnetism are discussed. Evidence is summarized involving a correlation between observed magnetic anomalies and ejecta blankets from impact events which indicates the possible importance of local mechanisms involving meteoroid impact processes in generating strong magnetic fields at the lunar surface. A reply is given to the latter argument which also presents recent evidence of a lunar iron core.

    A new interpretation of the Venera 11 spectra of Venus. I - The 0.94 micron water band (1984)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: Detailed band models for CO2 and H2O absorption are used to reinterpret Venera 11 spectra of the transmitted sunlight at several levels in the Venus atmosphere. An effective path approximation is used to allow for scattering in the clouds. The atmospheric model has 10 layers and uses 211 CO2 and 15 H2O vibrational transitions at 5/cm resolution. The conclusion of Moroz et al. (1979) that the 0.94 micron feature of the spectra indicates a sharp maximum in the water-vapor profile near 50 km is confirmed. It is also confirmed that such a profile fails to account for the spectra in the 1.13 micron water bands.

    Microwave and optical remote sensing of forest vegetation (1984)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: The objectives and anticipated results of a study to define the strengths and limitations of microwave (SIR-B) and optical (thematic Mapper) data, singly and in combination, for the purpose of characterizing forest cover types and condition classes are described. Other specific objectives include: (1) the assessment of the effectiveness of a contextual classification algorithm (SECHO); (2) evaluation of the utility of different look angles of SAR data in determining differences in stand density of commercial forests; and (3) the determination of the effectiveness of the L-band HH polarized SIR-B data in differentiating forest-stand densities.

    Airborne laser topographic mapping results (1984)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: The results of terrain mapping experiments utilizing the National Aeronautics and Space Administration (NASA) Airborne Oceanographic Lidar (AOL) over forested areas are presented. The flight tests were conducted as part of a joint NASA/U.S. Army Corps of Engineers (CE) investigation aimed at evaluating the potential of an airborne laser ranging system to provide cross-sectional topographic data on flood plains that are difficult and expensive to survey using conventional techniques. The data described in this paper were obtained in the Wolf River Basin located near Memphis, TN. Results from surveys conducted under winter 'leaves off' and summer 'leaves on' conditions, aspects of day and night operation, and data obtained from decidous and coniferous tree types are compared. Data processing techniques are reviewed. Conclusions relative to accuracy and present limitations of the AOL, and airborne lidar systems in general, to terrain mapping over forested areas are discussed.

    Pioneer Venus - Evolving coverage of the near-Venus environment (1984)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: The manner in which secular changes in the orbit of the Pioneer Venus Orbiter (PVO) research satellite influence its data collecting capabilities is discussed. A brief description of the propulsion system and sensor arrays of the satellite is presented, and the susceptibility of these systems to changes in power supply due to the decline in solar activity is considered. It is pointed out that the PVO should have enough fuel to continue to transmit data until after the arrival of Comet Halley in 1986, and that, during the 1991 to 1992 period, more moderate levels of solar activity will permit more accurate measurements of thermospheric and ionospheric parameters.

    An analysis of Landsat-4 Thematic Mapper geometric properties (1984)
    In:  Other Sources
    Details
    Publication Date: 2011-08-18
    Description: Landsat-4 Thematic Mapper data of Washington, DC, Harrisburg, PA, and Salton Sea, CA were analyzed to determine geometric integrity and conformity of the data to known earth surface geometry. Several tests were performed. Intraband correlation and interband registration were investigated. No problems were observed in the intraband analysis, and aside from indications of slight misregistration between bands of the primary versus bands of the secondary focal planes, interband registration was well within the specified tolerances. A substantial number of ground control points were found and used to check the images' conformity to the Space Oblique Mercator (SOM) projection of their respective areas. The means of the residual offsets, which included nonprocessing related measurement errors, were close to the one pixel level in the two scenes examined. The Harrisburg scene residual mean was 28.38 m (0.95 pixels) with a standard deviation of 19.82 m (0.66 pixels), while the mean and standard deviation for the Salton Sea scene were 40.46 (1.35 pixels) and 30.57 m (1.02 pixels), respectively. Overall, the data were judged to be a high geometric quality with errors close to those targeted by the TM sensor design specifications.
