| Abstract: | The radiance getting from thermal infrared sensor are the function of temperature and emissivity,so the temperature and emissivity seperation is a key problem to thermal infrared remote sensing for retrieving land surface temperature.This paper sums up the progress of land surface temperature;summarize several methods for temperature and emmisivity seperation;.analyse the advantage and disadvantage of each method.The future development trends for retrieving of land surface temperature are deal with in the end of the paper. |
