摘要
利用TM遥感数据 ,对迪庆州中甸县森林资源调查进行目视判读 ,对影像判读的关键检验指标———一致率、正判率进行分析 ,结果表明 :( 1 )一致率为 91 % ;面积地类综合正判率为 95 3%。均超过细则规定要求。 ( 2 )在不同的建标线路上及不同的地类中均获得了较高的和较为稳定的正判率。
The remote sensing data of forest resource survey of Zhongdian county were visually interpreted. Rates of consistency and accuracy, two key evaluation indexes of TM image interpretation, were analyzed. The evaluation results showed that the rates of consistency and comprehensive accuracy achieved 91% and 95.3% respectively, two indexes all exceeded the requirements of related detailed rules.
