摘要
文中利用Landsat-7 ETM+影像的多光谱和热红外波段进行光谱分析和地表温度反演,旨在开发一套提取城市不透水层的完整解决方案,特别是利用地表温度,从低反照率盖度影像中去除非不透水层信息,以便提高城市不透水层的评估精度。
In the paper, multi-spectral and thermal infrared bands of Landsat-7 Enhanced Thematic Mapper Plus （ETM＋） image were used to carry out the spectral analysis and the surface temperature inversion to develop a complete solution for extracting and mapping urban impervious surfaces. In particular, surface temperature was used to remove non-impermeable layer information from low albedo fraction image in order to improve the assessment accuracy of urban impervious layers.
