新型基础测绘自动制图软件的设计与实现

Design and Realization of a New Automatic Mapping Software for Basic Surveying and Mapping

传统的测绘基础数据建库与制图一体化方法,多采用地理实体信息与制图信息同时表达的数据模型,存在数据冗余、生产效率低的问题。针对该问题,本文提出了一种自动化制图技术方案;设计构建了一体化制图数据库模型;深入研究了基于符号级别、空间关系和要素权重的要素压盖关系处理算法。最后,开发自动化制图软件,并运用该软件进行山东省省级基础测绘数据制图,有效提高了制图效率,满足实际生产需求。

The traditional methods for basic topographic data to build database and cartographic integration commonly use the data model that expresses geographic information and cartographic information simultaneously,and that has problems with data redundancy and low productivity.For the problems,this paper presents a technical scheme of automated mapping,then designs and builds an integrated cartography database model.And it studies the processing algorithm of element overlapping relationship based on symbol level,spatial relationship and element weight.Finally,it develops automatic cartography software and uses the software to carry on the Shandong provincial basic survey data drawing.The software effectively improves the efficiency of mapping and meets the actual production needs.
