3D Geographic Entity Relationship Query System Based on Graph Database
In order to meet the demand for fast import and query of massive 3D geographic entities,this article is based on the efficient storage and fast query characteristics of graph database and combined with realistic 3D technology to create realistic 3D data,construct accurate 3D geographic entities of each household and realize relation query. This article uses geographic entity coding as a connec-tion,establishes entity relationships through a graph database,efficiently imports logical relationships between geographic entities into the graph database,connects geographic entity relationships,and provides basic geographic data services for urban public safety.
