The short wavelength infrared region (0·7-3·0μm) has manifold applications in the detection and monitoring of geoenvironmental features, such as coal mine fire, oil well fire, active volcanoes, industrial hot spots, etc. These features are essentially characterized by high temperatures and often release aerosols and greenhouse gases into the atmosphere. 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 brief. The pixel-integrated and sub-pixel temperatures have been calculated 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).
