| Abstract: | By means of advanced remote sensing,distribution and change of ground heat field can be monitored synchronously and continuously.In this paper,Changsha-Zhuzhou-Xiangtan was investigated as an example.The comparative light temperature of TM was analyzed,and a grade map of ground heat field was made by image enhance method and the density partitions.The results demonstrated the distribution and change rule of heat island in Changsha-Zhuzhou-Xiangtan urban area. |
| Keywords: | urban heat island remote sensing brightness temperature |
