【摘要】 遥感技术是进行全球及区域的大面积土地利用/土地覆盖研究中不可替代的信息获取方法,而MODIS数据是其重要信息源之一。随着MODIS数据在大面积土地覆盖分类的应用和发展,如何对其分类结果进行精度评价已引起广泛重视。利用东北地区100 a土地利用与土地覆盖数据库,建立适于应用目的且在实践中可行的评价方案,将高空间分辨率的遥感数据及其分类结果作为参考数据,对基于MODIS数据的东北地区土地覆盖分类结果进行分析和精度评价,并对相关问题进行了分析与探讨。更多还原

【Abstract】 The remote sensing technique is an unreplaceable information collection method for studying the large area land use/land cover, and moderate resolution imaging spectrometer(MODIS) data are its important information source. Along with the application and developement of MODIS data in the large area land cover classification field, attention has been drawn to the accuracy assessment of land cover classification results. In this paper, the land use and land cover database for Northeast China area is used to work out a practical classification accuracy assessment scheme, the high resolution remote sensing data and classification results are then taken as the reference data to make analysis and accuracy assessment of the Northeast China’s land cover classification results based on the MODIS data, and the problems related to the accuaracy assessment are also analyzed and discussed.更多还原
