Abstract
The pixel spatial resolution of TM6 is 120 m.With the information of the other TM bands,the authors can identify the earth surface types for each 30 m sub-pixel.And taking advantage of the fact that different types of earth surface have different characteristics of thermal inertia,the authors can determine the weight of each sub-pixel in the original pixel as well as the radiance value of the sub-pixel.Then the mono-window algorithm is used to calculate the temperature of the earth surface.Compared with the spatial distribution variation of surface temperature calculated by cubic convolution interpolation resampling method,the method proposed in this paper can get a better spatial distribution of the earth surface temperature.
