摘要
由于客观条件所限或为了提高工作效率,地图编制过程中对于点状要素的取舍通常由作业员人工操作,工作烦琐且作业效率低。为提高点状居民地在地图编制过程中的选取综合效率,本文基于Arcpy编写了点状居民地自动优化取舍工具,Python脚本工具实现了在选取点状居民地时,保留重要的点状居民地,对其余点按设定比例进行抽稀保留,最终优化选取的过程。更少的人工取舍,提高了制图与出图效率。
Due to objective conditions or in order to improve work efficiency,the choice of dot elements in map compilation is usually done manually by operators,which is tedious and inefficient.In order to improve the pitting residents in mapping in the process of selecting comprehensive efficiency,this paper Arcpy prepared pitting residents automatic optimization choice tools based on Python scripting tool implemented in the selection of pitting residents,residents retain important point for the rest,according to the set point ratio were sparing retention,final optimization selection process.Less artificial selection,improving the efficiency of drawing and drawing.
