摘要
基于DEM数据提取地形特征线存在诸多问题,结合数字图像处理技术对初步提取的地形特征线进行逐步优化,有效地解决了特征线的交叉、破碎、闭合等问题。实验证明:优化方案可行、可靠,为特征线的后续问题优化处理提供借鉴。
There are many problems in extracting the terrain feature line based on DEM. Discussion is made on how to optimize the basic terrain feature line through the technology of digital image disposal which effectively solves the crossing, fragmentation, closing and so on. The relative experiment has proved that the optimization study is feasible and safe,which can provide the references for the later optimization.
