基于ArcGIS提取第三次国土调查图斑未变化的边线

Extracting the unchanged boundaries of the thirdnationwide land survey map spots based on the ArcGIS

在生产的过程中,如何辅助检查人员判断地物边界采集是否准确,为管理人员评估图斑采集质量提供依据,快速准确地提取出三调图斑与二调图斑的重合边界,实时计算重线图斑数量的占比情况,是其中一个重要手段。文中详细地分析了数据情况和技术要求,提出了一种基于ArcGIS平台模型构建器自动提取重合图斑边界的方法。这种方法封装了详细复杂的处理流程和顺序,有效地避免了单个工具处理产生的各种冗余数据,操作简单,大大提高了处理效率。

In the process of third nationwide land survey data production,how to assist the inspector to judge whether the boundaries collection of the ground feature was accurate,provide a basis for the manager to evaluate the quality of the map spot collection,extract the overlapped boundaries of the three-tone map spot and the two-tone map spot quickly and accurately,and calculate the proportion of the number of double-line map spots in real time was one of the important means.In this paper,the data situation and the technical requirements were analyzed in detail,and the method of extracting overlapped map spots boundaries was proposed based on ArcGIS platform model builder.Detailed and complex processing procedures and sequences were encapsulated by this method,and various redundant data generated by the single tool produces was avoided effectively,and the operation was simple improving processing efficiency greatly.
