Location of Septic System Failures in Southwest Missouri Using False Color Infrared Photography
Locating septic system failures with false color infrared photography is a viable method of environmental evaluation that can be used as part of an education program designed to increase public and official awareness. Septic system failures are a problem in southwest Missouri due to their extensive …

Development of a Geographic Information System as an Analysis Tool for Management of Black-capped Vireo on the Kerr Wildlife Management Area, Kerr County, Texas
… and white aerial photographs, digital orthophoto color infrared aerial photography, vegetation, topography, soils, incidence of parasitism, prescribed burning and wildfire, water sources, roads, and pastures on the Kerr Wildlife Management Area. The Black-capped Vireo GIS will enable analysts to …

Methods to achieve wavelength selectivity in infrared microbolometers and reduced thermal mass microbolometers
The use of a patterned resistive sheet as an infrared-selective absorber, including the effects of a mechanical support dielectric layer is discussed. Also, modified dielectric coated Salisbury Screen can improve both the wavelength selectivity and the speed of thermal response for microbolometers. …

Landscape level raptor habitat associations in northwest Connecticut
… black and white and 1:58,000 and 1:126,000 color infrared aerial photography. Among-species nest area analyses at the ground level indicated that higher beech and red maple densities were associated with red-shouldered hawk nest areas than with nest areas of barred owls or northern goshawks. …

Remote Sensing for Precision Agriculture: Within -Field Spatial Variability Analysis and Mapping With Aerial Digital Multispectral Images
Unsupervised clustering of color infrared (CIR) image of a field soil was able to identify soil mapping units with an average accuracy of 76%. Spectral reflectance from a crop field was highly correlated to the chlorophyll reading. A regression model developed to predict nitrogen stress in corn …
