A technique for mapping thermal infrared radiation variation within land cover

In this letter, a technique for mapping the thermal infrared radiation variation within land cover using both a classification map and a thermal infrared image is proposed. Furthermore, a technique to effectively calculate the average thermal radiance for each land cover from Thematic Mapper (TM)-type sensors, which aquire high resolution of visible and near-infrared images and low resolution of thermal infrared images, was also proposed. These techniques provide useful information on processing TM-type sensors for urban heat monitoring, vegetation diagnosis monitoring, forest fire monitoring, and so forth.
