摘　　要：测绘数据采集的过程中因种种原因,将难免出现不符合要求的数据,而人工检查这些数据,一是数据量大,检查时间长;二是检查效率低,且不能保证完全符合要求。鉴于此,利用AutoCAD自带的Visual Lisp语言编写程序,对图形中存在的悬挂点进行检查。检查以程序设定的点与线的距离为限,程序将自动统计悬挂点的个数。该程序在10 000个目标样本中进行试用,在约2minr的时间内找到了所有悬挂点(大概有1 000个左右),所找到的悬挂点准确无误,极大的提高了工作效率及成果的准确性。During the surveying and mapping data acquisition,since much all sorts of causation,undesirable data are hardly to be avoided.While to use manual checking,because of generous data,long checking time and low efficiency,furthermore,complete satisfactory can not be assured.In view of this,using Visual Lisp language programming the AutoCAD included,carry out checking of terminal vertexes existed in graphics.The checking is limited in program stated distances between points and lines,and the program will count numbers of terminal vertex automatically.After tryout in 10000 samples,find out about 1000 terminal vertexes within 2 minutes,and accurate.Thus greatly improves working efficiency and result accuracy.
