摘要
城市土地利用变化检测为城市规划和管理提供有用信息。但是目前很多变化检测方法都离不开人工干预,其结果在一定程度上依赖于人的经验。方向矢量法是将多时相遥感数据中不同地物类型间的光谱差异利用方向矢量反映在多维空间中,进而建立类型转换模型。该方法避免了依赖人的经验所带来的不便和误差,并且简单、直观、易操作。通过对北京奥运村地区高分辨率遥感影像的检测,分析了方向矢量检测法在城市土地利用变化检测中的应用。
The change detection of urbav land-use supplies valuable information for urban design and management, However, most of methods in change detection are not hand-free, and results are based on human＇s experience. Direction-vector analysis is to reflect object＇s,spectrum differences among multi-temporal remote sensing images in multi-dimension space by using direction-vector and to build transfer model between types, The method avoids inconvenience and error from human＇s experience, and is simple, observable and operable. The paper employs change detection to Olympic village in Beijing to explain the application of direction-vector in urban land-use change detection.
