Abstract

The invention provides a large-scale two-dimensional and three-dimensional space data search engine based on a network. The large-scale two-dimensional and three-dimensional space data search engine structurally comprises a space indexer module, a space server module and an application program interface module. The spatial indexer module is used for establishing a spatial index record database. The space server module comprises a queue response processor and a solr search server module. The application program interface module comprises a query interface and a feedback interface. The output end of the spatial index record database and a query interface of the application program interface module are respectively connected with the solr search server module, and the output end of the solr search server module is connected with a feedback interface of the application program interface module and is output to the outside through the feedback interface. According to the method, modular design is adopted, data of different scales can be searched for conveniently, expansion is easy, the query speed of large-scale two-dimensional and three-dimensional space information is greatly increased, and the quality of a data source and the retrieval accuracy are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a network-based large-scale two-dimensional and three-dimensional space data search technology. Background technique [0002] With the rapid development of computer technology and the rapid growth of social demand, the application of spatial data is becoming more and more extensive. Among them, map platforms such as AutoNavi and Baidu are for civilian use, and large-scale geographic information systems such as ArcGIS and HyperMap are for commercial use ( GIS) are all established on the basis of spatial data; at present, for the application of spatial data, the search of large or even massive spatial data has become a key problem in the above-mentioned systems, especially two-dimensional (such as road information) and three-dimensional (such as building information) highly combined has become the difficulty of spatial search. Therefore, how to learn from the big dat...
