Abstract

The invention discloses a network geographic information service system based on three-dimensional model tiles. The network geographic information service system comprises a client, a structure database, a file database, a web server and a local cache server. The client is connected with the web server; and the web server is connected with the structure database, the file database and the local cache server. Through the slicing technology, various visual data which needs to be displayed and comprises a three-dimensional model is segmented into tiles according to an organization structure; theaddress information is stored in a structure database; the file database is connected and combined with the local cache server during calling, so the three-dimensional model in the view range can be quickly loaded, the loading speed and efficiency of the three-dimensional model are improved, and a user group of the network geographic information service system has better user experience.

Description

technical field [0001] The invention relates to the field of map services, in particular to a network geographic information service system based on three-dimensional model tiles. Background technique [0002] Geographic Information System (GIS, Geographic Information System) is a comprehensive subject, combining geography and cartography, remote sensing and computer science, has been widely used in different fields, is used for input, storage, query, analysis and display The computer system of geographic data, in recent years, also called GIS as "geographic information service". Three-dimensional GIS is the performance and display of data after collection and calculation and analysis. Compared with two-dimensional data, three-dimensional data can show more objective reality, because the display of spatial information is more intuitive, and the multi-dimensional spatial analysis function is more powerful. [0003] WebGL (Web Graphics Library) is a 3D drawing protocol. This...
