| 摘 要： | 建立海岸线预测系统是为了实现海岸线预测的量化和自动化。系统分由三个部分组成:遥感影像海岸线边缘提取与矢量化、海岸线相关因子计算(变化速率与分维度)和海岸线变化趋势预测。以海岸线遥感影像为数据,通过八邻域法海岸线边缘提取及矢量化、海岸线相关因子计算两个功能模块的处理,基于GM(1,1)模型的海岸线变化趋势预测模块对输入的四期矢量海岸线数据建立GM(1,1)模型,根据用户输入的预测原点和预测精度,得到若干预测点,继而得到预测的海岸线轮廓。系统采用C#语言基于ESR I ArcOb jects的开发来实现。该系统在辽宁省国土资源规划地理信息系统中得到应用和推广。

| Abstract: | Coastline change forecast system was designed to implement quantification and automation of coastline change forecast.System contained 3 parts: coastline edge extraction and vectorization,correlation factor calculation and coastline change forecast.Remote sensing images were processed by three models: coastline edge extraction with eight-neighborhood method and vectorization model,and correlation factor calculation model.Then coastline change forecast model established series GM(1,1) models based on vector ... |
