The selection of the best possible Landsat TM band combination for delineating salt-affected soils

Land cover classification and economic assessment of citrus groves using remote sensing

“…Remotely sensed image data have been used to monitor salinity stress in citrus trees (Craig and Shih, 1998), delineation of saline soils (Dwivedi and Rao, 1992), and the detection of insect infestations (Riley, 1989), such as pest-affected hardwoods (Vogelmann and Rock, 1989). In studies of general vegetation spectral reflectance, the near-infrared (IR) band (0.75 μm-1.35 μm) is important in separating healthy and stressed trees based on leaf air content and the condition of the mesophyll layer; healthy leaves with more air and a thicker mesophyll increase near-IR scatter (Gausman, 1974).…”

A forward/backward principal component analysis of Landsat-7 ETM+ data to enhance the spectral signal of burnt surfaces

“…Apart from change detection, (Byrne et al, 1980;Fung and LeDrew, 1987;Lodwick, 1979;Muchoney and Haack, 1994;Richards, 1984;Singh and Harrison, 1985) PCA has been applied to determine the underlying dimensions of remotely sensed data (Anuta et al, 1984;Ready and Wintz, 1973;Townshend et al, 1985), for image enhancement (Gillespie, 1980;Richards, 1986), image data compression (Gonzales and Wintz, 1977), merging multiresolution and multispectral data (Chavez et al, 1991), land-cover characterization (Hirosawa et al, 1996) and other research topics (Ahearn and Wee, 1991;Canas and Barnett, 1985;Conese et al, 1988;Dwivedi and Rao, 1992;Eastman and Fult, 1993;Ingerbritsen and Lyon, 1985;Jiaju, 1988;Loughlin, 1991;Siljeström and Moreno-López, 1995).…”

Modeling and Mapping of Soil Salinity with Reflectance Spectroscopy and Landsat Data Using Two Quantitative Methods (PLSR and MARS)

“…Several studies have shown the visible, near infrared, or short-wave infrared spectral bands from the optical sensors to be promising for the detection of surface soil salinity [11][12][13][14][15]. In addition, hyperspectral data have been successfully used in several studies on soil salinity, enabling quantitative assessment of salt-affected soils [16][17][18][19][20][21][22].…”
