【摘要】 本研究以Landsat TM遥感数据为研究对象,以杂谷脑河流域为例,从遥感数据的几何校正、最佳波段选择、图像融合、图像裁剪、土地分类和图像的解译角度进行了处理。之后,将校正后的数据进行了矢量化并得到DEM,在DEM的基础上进行了高程、坡度、坡向方面的分析,得到了有利于LUCC分析的可靠数据。更多还原

【Abstract】 This study,using Landsat TM remote sensing data as research object,taking Zagunao River Basin as an example,treats from the points of view of the geometric correction of remote sensing data,the best band selection,image fusion,image cropping,land classification and image interpretation.After the vector of the corrected data,it gets DEM.Based on the DEM,it analyses from the aspects of the elevation,slope,and aspect,then achieves reliable data in favor of LUCC analysis.更多还原
