Embodiment Construction
[0009] The application is described below by the examples, as figure 1 As shown, the present invention provides a network-based large-scale 2D and 3D spatial data search engine, and its structure includes: a spatial indexer module, a spatial server module and an application program interface module. The spatial indexer module is used to build an index record database; the spatial server module includes a queue response processor and a solr search server; the application program interface module includes a query interface and a feedback interface. The output terminal and query interface of the spatial index record database are respectively connected to the solr search server module, the output terminal of the solr search server module is connected to the feedback interface, and the indexes for different data types (two-dimensional or three-dimensional) are output to the outside world through the feedback interface result.
[0010] The spatial data search engine provided by the...
