基础地理实体关系设计与试验

Design and experiment of fundamental geo-entity relationship

针对目前基础地理实体关系难以构建和使用复杂等问题,通过分析已有实体关系类型,归并、化简、重新分类已有实体关系类型;设计实体关系一体化存储模型,并梳理出所有基础地理实体分类中存在的基础关系;通过编制实体关系构建表和实体关系构建批处理程序,实现了基础地理实体关系的快速批量构建,验证了实体关系的使用效果。试验结果表明,该文提出的实体关系技术方法,便于实体数据关系的构建,在数据应用中也较为方便,在新型基础测绘和实景三维建设中,具有一定的参考和推广使用价值。

It is difficult to construct and use the semantic relationship of fundamental geo-entity.This paper first analyzes the existing entity relationship types,and merges,simplifies,and re classifies the existing entity relationship types.Then design an entity relationship integrated storage model and sort out the basic relationships existing in all fundamental geo-entity classifications.Finally,by compiling the entity relationship construction table and the entity relationship construction batch program,the rapid batch construction of the entity relationship is realized.Verified the use effect of this entity relationship.The experimental results show that the entity construction method proposed in this paper is convenient for the production of entity data relations and is also convenient in use.It has certain reference and promotion practical value in the new basic surveying and mapping and 3DReal Scene construction.
