TL;DR: In this article, the relationship between various linear combinations of red and photographic infrared radiances and vegetation parameters is investigated, showing that red-IR combinations to be more significant than green-red combinations.

TL;DR: In this paper, the authors collected red and photographic infrared data with a hand-held radiometer under a variety of conditions at 4 to 12-day intervals throughout the growing season and were used to monitor corn and soybean growth and development.

TL;DR: In this paper, a method for estimating the thermal properties of soils for changes in composition, porosity, and moisture content is presented in a contour format to allow the user to evaluate the usefulness of thermal inertia mapping for his particular application.

TL;DR: In this paper, a quasi-single-scattering diffuse reflectance model developed by Gordon and coworkers was used to test mathematical models relating diffuse reflectances to aquatic suspended solids concentration, and the Gordon model applied to 33 points of MSS 5 data combined from three dates produced r = 0.98.

TL;DR: In this article, a high-frequency radar system has been used at coastal locations for measurement of surface current and wave fields for tsunami detection and warning system, which can detect the presence and magnitude of a tsunami as it approaches the shore by observing the to-fro current pattern produced by the orbital velocity of the tsunami wave.

TL;DR: In this article, the spectral biconical reflectance factor (BSF) of four vegetated surfaces was used to derive its variability with differing distributions of the irradiance, and it was found that the variability of the albedo with respect to atmospheric turbidity is less than 0.01 in nearly all cases.

TL;DR: In this paper, the thermal emissivities of exposed soil surfaces for the major soil subgroups of Alabama, Georgia, and Florida were determined, and it was found that brightness temperature sensed by narrow-band infrared radiometers (10.4-12.6 μm), as used on SMS-GOES spacecraft would not deviate from thermodynamic temperatures by more than -2°C as a result of surface emissivity.

TL;DR: In this article, the authors considered the physiology literature with a view to outlining factors that may be relevant in inferring soil water content from canopy temperature and discussed examples of energy fluxes and temperatures observed under field conditions.

TL;DR: LANDSAT Multispectral Scanner data covering a three-county area in northern Illinois were classified using computer-aided techniques as corn, soybeans, or “other,” and county estimates of the area of corn and soybeans agreed closely with those made by the USDA.

TL;DR: In this article, an empirical model to estimate foliage density, i.e., leaf area index (LAI), using LANDSAT multispectral scanner (MSS) data was developed.

TL;DR: In this article, the authors used panchromatic film and false-color infrared film to measure the soil surface moisture in a peat soil and a sandy loam in the field.

TL;DR: An operationally meaningful measure of success of prediction is proposed and an example using corn blight data demonstrates the value of this new index and casts some doubts on earlier conclusions based on the percent correct classification criterion.

TL;DR: In this paper, the authors combine the stress-degree-day concept of plant water stress assessment with the growing degree-day concepts of plant phenological development to predict grain crop yields.

TL;DR: In this paper, the authors measured the spectrum of cereals, grasses, and corn from preflowering to early maturity and found that the effect of angular scattering on radiance decreased with maturity.

TL;DR: In this article, the use of the factor analysis algorithm for determining optimal parameters of remote observations, taking account of broad requirements put to information in complex studies of the environment and earth resources, is suggested.

TL;DR: In this article, a sequence of burned surfaces aged 0, 1, 2, 25 and 80 years was investigated regarding changes in the spectral distribution of reflected light Controls were introduced to isolate diurnal and seasonal effects.

TL;DR: In this paper, a 14 man-month pilot study was made using multivariate statistical methods of merged datasets from quantified geological, geophysical, and LANDSAT data, and the results included contoured probability maps of uranium prediction, with analysis of the role and the relative contribution of each of the 43 parameters.

TL;DR: In this paper, a long-term observational program on the microwave scatter and emission behavior of snow began in 1977 at a high-altitude Alpine test site and the brightness temperatures at 4.9, 10.5, 21, 36, and 94 GHz measured at different incidence and polarization angles during the first season are analyzed with the aid of correlation, factorial, and cluster algorithms.

TL;DR: In this article, the effects of timing variations on the shape of the average return pulse shape are discussed in detail, and accurate calibration of the sampling gates that measure this shape is particularly critical.

TL;DR: In this paper, the authors describe methods to monitor change of soil surface properties and the implications of these changes for recording bare soil patterns, or changes in soil moisture content, on photos or linescan images.

TL;DR: In this paper, the authors used enhanced nighttime thermal infrared imagery and digital data from a NOAA polar orbiting satellite to map drainage patterns and landforms in North and South Dakota, including the Missouri Escarpment from Saskatchewan to the Nebraska border, the Manitoba Escarpments, Coteau des Prairies, recessional moraines on the Citeau du Missouri and partial drainage boundaries for the following rivers: James, Big Sioux, Minnesota, Red of the North, Souris, and the main stem of the Missouri plus its western tributaries in the Dakotas.

TL;DR: In this article, the relationship between airborne and ground-based measurements of soil and crop canopy temperatures was investigated for a partial crop canopy, and it was found that the airborne measurements were virtually identical to ground based measurements, with a regression line slope of 0.985, a standard deviation of 1.8 C and a correlation coefficient of 097.

TL;DR: In this paper, the combined use of additive viewing and digital processing of LANDSAT-2 imagery of part of the Pantanal of Brazil has allowed detailed maps of the drainage network to be constructed.

TL;DR: In this article, a remote sensing application project to assist the Mississippi Park Commission in selecting a suitable site for a proposed state park in Adams County, Mississippi, was described, and a study area of approximately 130,000 acres was selected.

TL;DR: In this paper, a false color infrared composite of Landsat bands 4, 5, and 7 is investigated and its influence upon classification errors is partially determined, where the color display is used in labeling training data.
