摘要
利用 1998年 8月 4日上海幅TM6图像 ,经定位、配准、纠正、图像处理、噪声剔除、亮温标定及特征提取等步骤 ,得出上海市亮温分布场 ,同时对其热力景观、细部结构及其成因做了分析。实践证明 ,TM6图像可作为城市热环境质量评价、生态城市规划的背景资料和依据。
The luminance temperature distribution of Shanghai urban area was surveyed by means of locating, rectifying , image processing, noise erasing, temperature calculating and characteristic extracting from TM infrared data of 8/4,1998. The intensity, spatial structure and cause of UHIE (Urban Heat Island Effect) were investigated and discussed. It is shown that Thematic Mapper data are quite useful for thermal environmental quality appraisal and ecological urban planning.
