摘要
数字海图生产过程中,海洋陆地层面要素和线要素的校对检测是海图校对检测的重点与核心。通过对数字海图海洋陆地层面要素、线要素和水深层数据的综合分析研究,按照航海图书编绘规范要求,基于ArcInfo地理信息系统软件平台,应用AML宏语言,主要解决了面要素的编码属性自动识别、识别结果与作业结果自动比对、面要素综合错误自动检测和多余面要素自动检测等关键问题,实现了海洋陆地层线要素与面要素的自动校对检测。
During the production process of digital charts,checking on the face primitive and line features of submarine land coverage is proofreading core of charts.By the way of analyzing synthetically of digital chart primitive and line features of submarine land coverage,and data of sounding level,according to the requirement of navigational publications editing and charting,on the basis of ARC/INFO geological information system software platform,applied AML macro language,this paper mainly solves the key problems such as the coding attribution automatic identification of,face primitive,automatic comparison the results of automatic identification and charting by hand,automatic checking of face primitive complex mistakes,automatic checking of unnecessary face primitive and etc.and achieves the automatic checking of face primitive and line features of submarine land coverage.
