摘要
在新型基础测绘建设背景下,存在传统基础测绘数据向新型测绘产品基础地理实体数据统一转换生产困难的问题.知识图谱是数据互联迈向知识互联服务的基础.本文首先对基础地理要素与基础地理实体进行本体建模;利用图数据库技术,将基础地理要素与基础地理实体的分类及其映射关系进行语义化存储,构建基础地理信息知识图谱;最后以房屋实体生产为例进行实验验证图谱驱动生产的可行性.该方法为新型基础测绘中基础地理实体数据的转化生产提供了新思路.
Abstract
Under the background of new fundamental survey-ing and mapping construction,there is a problem that it is diffi-cult to transform traditional fundamental surveying and map-ping data into fundamental geo-entity data of new surveying and mapping products.The knowledge graph is the basis of data interconnection moving towards knowledge interconnec-tion service.Firstly,this paper models the ontology of funda-mental geo-elements and fundamental geo-entities.Second-ly,graph database technology is used to semantically store the classification of fundamental geo-elements and fundamen-tal geo-entities and their geometric mapping relationships.Fi-nally,experiments are conducted to verify the feasibility of graph-driven production by taking housing entities production as an example.The method provides a new idea for the trans-formed production of fundamental geo-entity data in new fun-damental surveying and mapping.
