Journal ArticleDOI
TL;DR: In this paper, a stochastic leaf radiation model was used to predict leaf spectral reflectance as a function of leaf water content for a dicot leaf, and simulated spectral reflectances were analyzed to quantify reflectance differences between different equivalent water thicknesses.

Journal ArticleDOI
TL;DR: In this article, two four-channel Landsat scenes of the same area, which were recorded on different dates, were superimposed and treated as a single eight-dimensional (channel) data array.

Journal ArticleDOI
TL;DR: In this paper, a composite method has been developed to calculate actual evapotranspiration rates from remotely sensed crop surface temperatures, with the aid of the energy budget equation and aerodynamic heat and water vapor transport equations, while incorporating soil-plant-water relations.

Journal ArticleDOI
TL;DR: In this paper, the thermal infrared sensor response from a wheat canopy was extremely non-Lambertian because of spatial variations in energy flow processes; the effective radiant temperature of the sensor varied as much as 13 C with changing view angle.

Journal ArticleDOI
TL;DR: In this article, a study of the interpretation errors in the application of Landsat imagery to land-use planning and modeling is reported, where potential errors associated with the misalignment of pixels after geometric correction and with misclassification of land cover or land use due to spectral similarities were identified on interpreted computer-compatible tapes of a portion of Franklin County for two adjacent days of 1975 and one day of 1973.

Journal ArticleDOI
TL;DR: In this paper, the effects of vegetation canopy structure on thermal infrared sensor response must be understood before vegetation surface temperatures of canopies with low percent ground cover can be accurately inferred.

Journal ArticleDOI
TL;DR: The hairy-nosed wombat (Lasiorhinus latifrons) is a large marsupial that occurs in great numbers on the Nullarbor Plain, South Australia as mentioned in this paper.

Journal ArticleDOI
TL;DR: In this paper, the environmental effects of the fire were studied in the field and from aircraft and Landsat data, and three categories of burn severity were delineated using an August 1977 Landsat scene acquired shortly after the fire stopped.

Journal ArticleDOI
TL;DR: In this paper, the utility of spaceborne microwave radiometers for monitoring snow depths in different geographic areas was investigated in the Canadian high plains, the Montana and North Dakota high plains and the steppes of central Russia, and significant regression relationships between snow depth and microwave brightness temperatures were developed for each of these homogeneous areas.

Journal ArticleDOI
TL;DR: In this article, multifrequency airborne radar image data of SP Mountain and SP flow in northcentral Arizona were obtained in diverse viewing directions and direct and cross-polarization and compared with surface and aerial photography, Landsat multispectral scanner data, airborne thermal infrared imagery, surface geology, and surface roughness statistics.

Journal ArticleDOI
TL;DR: In this paper, a laboratory radiometric method for the rapid determination of green and brown vegetation percentages in clipped grass samples has been developed and tested and used for remote sensing of vegetation ground-truth work where the determination of dry green biomass in clipped samples is necessary.

Journal ArticleDOI
TL;DR: In this article, a spectral sampling and measurement program was conducted to accurately characterize the surface spectral reflectance of the Landsat resolution element and, for the first time, to establish statistically the degree of sampling required for a variety of natural terrains.

Journal ArticleDOI
TL;DR: In this paper, an approximate explicit formula is derived for the earth-atmosphere system nadir-beam reflectivity in terms of the atmospheric parameters, object pixel reflectivity and surrounding area reflectivity for the limiting case of an optically thin atmosphere.

Journal ArticleDOI
TL;DR: In this paper, the authors examine some impacts of remote sensing on geography and find that the exploitation of the improved or unique information available to the geographer via the application of remote-sensing techniques has barely begun.

Journal ArticleDOI
TL;DR: In this article, the authors used a simplified version of the transmittance function of Prabhakara et al. (1974) with three infrared bands, which yields an rms error of ± 1.1 K.

Journal ArticleDOI
TL;DR: The most common field size observed in this study was 10 acres for most crops studied and the field area and size distributions reported in the present investigation are derived from a representative subset of a stratified random sample of LACIE sample segments.

Journal ArticleDOI
TL;DR: A 4 km wide zone along the south Texas coast was interpreted from patterns of water turbidity visible in aerial photographs taken during a winter day of moderate northerly winds as mentioned in this paper.

Journal ArticleDOI
TL;DR: In this article, the microwave emission characteristics of the Colorado Rocky Mountain snowpack in the vicinity of Fraser, Colorado during the winter of 1978 were studied using the spectral signatures of 5.0, 10.7, 18, and 37 GHz radiometers.

Journal ArticleDOI

TL;DR: In this paper, the effect of atmospheric conditions on remote sensing of vegetation parameters was examined by studying variations of the ratio of the simulated radiance in the 0.76-0.90 μm [TM4 band of the multispectral scanner system (thematic mapper) of the Landsat-D satellite.
