An open multi-source 2D and 3D geographic information data aggregation and publishing system

Abstract

The invention discloses an open multi-source two- and three-dimensional geographic information data aggregation and publishing system, which belongs to geographic information technology, and is characterized by comprising: a service configuration management module, a data service publishing module, a service acceleration module and a service access module; The connection relationship between the modules is: the service access module sends the service access request to the service acceleration module, the service acceleration module forwards the service access request to the service publishing module, and the service publishing module queries the configuration information in the service configuration management module according to the service access request Library, to obtain the configuration information of the service and the connection information of the data contained in the service. The service publishing module publishes the service according to the obtained data connection information, and sends the service result to the service acceleration module. The service acceleration module caches the service result and forwards the service result to The service access module completes the service access request. Advantages: realize the integrated management of massive data, and realize the integration and seamless connection of multi-source data.

Description

technical field [0001] The invention relates to the technical field of geographic information, and specifically provides a management function of massive geographic information data, and publishes and shares the massive data in the form of a service. It is an open multi-source two- and three-dimensional geographic information data aggregation and publishing system that ensures the shareability and high availability of multi-source geographic information data and reduces the insecurity of direct access to geographic information. Background technique [0002] In the 21st century, the Internet has become popular rapidly and has grown into a new generation of distributed computing platform, on which a large number of data resources, computing resources and application resources are deployed. As a new Web application mode, Web service marks the transformation of the new generation of Internet software, and has become the mainstream computing scope of distributed computers. [00...
