Css. Reddy et al., APPLICATION OF THEMATIC MAPPER SHORT-WAVELENGTH INFRARED DATA FOR THEDETECTION AND MONITORING OF HIGH-TEMPERATURE RELATED GEOENVIRONMENTALFEATURES, International journal of remote sensing, 14(17), 1993, pp. 3125-3132
The short wavelength infrared region (0.7-3.0 mum) has manifold applic
ations in the detection and monitoring of geoenvironmental features, s
uch as coal mine fire, oil well fire, active volcanoes, industrial hot
spots, etc. These features are essentially characterized by high temp
eratures and often release aerosols and greenhouse gases into the atmo
sphere. In the present article, an attempt has been made to study the
applications of Thematic Mapper (TM) Short Wavelength Infrared (SWIR)
bands (4, 5 and 7) data for the detection and monitoring of these high
temperature related geoenvironmental features. The rationale of using
the SWIR data for temperature related studies is also discussed in br
ief. The pixel-integrated and sub-pixel temperatures have been calcula
ted using the TM SWIR bands data for an active volcano (Barren Island
volcano), coal mine fire (Jharia Coal Field) and industrial hot spots
(Bokaro Steel Plant).
