摘要
每年开展的土地利用变更调查,为国家宏观调控及土地的规划、管理、保护和合理利用提供了重要基础。本文以3S技术为基础,以QuickBird影像为例,分析和总结了高分辨率影像正射影像图制作的详细技术流程,同时探讨了第二次土地调查中土地利用变化图斑制作的方法,为今后3S技术在土地利用变化图斑更新及变化检测方面提供借鉴,并积极探索图斑更新的其他方法。
As one of the most important updating resources for land use change investigation,remote sensing is becoming popular.Based on the 3S technology,and taking Quickbird image for example,the paper analyzed and summarized the detailed methods of making DOM focused on high-resolution remote sensing images.At the same time,discussed some ideas for making change patches of land use in the second national land investigation,and provided some experience of updating and change detection for land use change patches.At last,explored some other processing methods of updating of change patches.
