摘　　要：界址签章表是权籍调查表中非常重要的表之一,在实际的作业过程中,常常使用手工填写或者根据已有数据库进行生成,其作业效率低下且容易出错。本文在结合已有相关算法的基础之上,直接从AutoCAD图面提取宗地范围线周围的相关地物信息或文字注记,将所提取信息进行缓冲区分析、叠盖分析、数据融合等处理之后,生成最终用于填写界址签章表的数据。实践表明,该算法不仅能够满足生成界址签章表的要求,而且效率高,错误率低,能够有效地降低劳动强度,满足实际的生产需要。The boundary signing table is one of the most important tables in the right questionnaire.In the actual operation process,it is often manually filled in or generated according to the existing database,and its operation efficiency is low and error-prone.Based on the existing related algorithms,this paper extracts the relevant feature information or text annotation around the parcel range line di-rectly from the AutoCAD drawing,and performs the buffer analysis,overlay analysis,data fusion and other processing on the extracted information.After that,the data that is finally used to fill in the boundary signing table is generated.Practice shows that the algorithm can not only meet the requirements of boundary signing table,but also has high efficiency and low error rate,which can effectively re-duce the labor intensity and meet the actual production needs.
