摘要
以重庆市彭水土家族苗族自治县为试验区,对森林资源二类调查目视解译的技术进行探讨,并对比分析计算机自动解译相对于目视解译的不足。森林资源目视判读存在很多人为主观性,常产生一些误差,而SPOT5遥感影像具有高空间分辨率和多光谱分辨率,可提供丰富、可靠、高精度的基础数据。
Taking the Tujia and Miao Autonomous County of Chongqing as Pengshui test areas,the visual interpretation techniques to the second type of forest resources survey were discussed, moreover, the shortages of automatic computer interpretation were analyzed through comparing with visual interpretation. There were human subjectivity during the visual interpretation of forest resources,therefore,there were always many errors, but SPOT5 remote sensing images with high spatial resolution and multi-spectral reselution,can provide rich,reliable and accurate basic data.
