ArcScan在土地利用数据缩编中的应用

The Application of ArcScan in Land use Data Generalization

基于矢量数据进行图斑中轴化剖分合并的土地利用数据缩编处理方法存在不足,本文介绍一种将矢量数据栅格化后在ArcScan环境下进行自动矢量化的解决方法,并通过实例验证了该方法的有效性和实用性。

The common generalization methods based on vector data have disadvantage with generating skeleton edges.The author gives a way to convert vector to raster data and then vectorized automately under the ArcScan software environment,and gives an example to prove its practicability and efficiency.
