高-中-低精度遥感的大区域高精度耕地面积估测分析

摘要

This paper introduced the method utilized in remote sensing sampling monitoring both in domestic and foreign countries, and analyzed the advantages and limits of remote sensing sampling monitoring used for the estimation of cultivated land area in large region, finally provided the solutions to accurately monitor a wide range of cultivated land by sampling the high - resolution, mid-resolution and low - resolution of remote sensing images step by step.%介绍了国内外的遥感抽样监测方法,分析了遥感抽样监测在大范围耕地监测中的优越性与局限性,最后就大范围高精度的耕地监测提出了采用高-中-低分辨率遥感影像逐步抽样的解决方案.
