摘　　要：为解决矢量数据生产过程中出现的等高线沟头直连问题,本文在分析现有作业流程的基础上,提出了基于ArcPy和FME的两种等高线沟头直连快速修编方法,并基于某矢量数据生产项目的等高线数据,对提出的两种方法进行试验验证,将其与人工作业模式的效率和数据质量进行对比。结果表明,在处理效率上,基于FME的实现方法处理效率最高,基于ArcPy的实现方法次之,人工效率最低;在数据质量方面,基于ArcPy的实现方法与人工作业模式大致相当,基于FME的实现方法修编效果稍差。本文研究成果可为类似矢量数据的处理提供参考。In order to solve the problem of contour line gully direct connection in the process of vector data production,this paper proposes two rapid revision methods of contour line gully direct connection based on ArcPy and FME by analyzing existing work processes.Based on the contour line data of a vector data production project,two methods are tested and verified,and the efficiency and data quality of the two methods are compared with manual operation mode.The results show that the processing efficiency based on FME is the highest,followed by the method based on ArcPy,and the manual efficiency is the lowest.In terms of data quality,the implementation based on Arcpy is roughly equivalent to that of the manual operation mode,and the effect of FME is slightly poor.The results from this paper can provide useful reference for the application requirements similar to vector data processing.
