Embodiment Construction

[0010] The technical difficulty to be solved by the present invention is how to provide an effective heterogeneous geographic data query mechanism for portable devices to meet various geographic information application requirements.

[0011] Such as figure 1 , Provide data examples Signal receiving devices include various types of monitoring devices, ground signal receiving devices, data receiving devices, workstations and other equipment. Monitoring devices include observation satellites, stations, etc. There will be different monitoring equipment for different fields; each monitoring equipment has a corresponding ground signal receiving device, such as ground signal receivers, data receiving stations, etc. These devices provide us with the most original measured data, which will be stored in workstations scattered in various places according to instructions. It will be difficult to perform effective query processing for data integration operations.

Abstract

The invention provides geographic data query system and method, in particular to heterogeneous geographic data query system and method. The system at least comprises one signal receiving device, one heterogeneous data storage device, a complete heterogeneous geographic data query system, wireless communication hardware and an intelligent terminal, wherein the signal receiving device receives monitoring data and stores the data in workstations distributed in all regions; the heterogeneous geographic data storage device takes charge of classifying, normalizing and permanently storing the data on the workstations. When a query request of the intelligent terminal is received, whether a user is authorized is checked, and query the heterogeneous geographic data by the heterogeneous geographic data query system after the check of the authorization of the user is confirmed. After being agreed by wireless communication hardware responsible person and corresponding agents, the query results are sent to the terminal. The invention can effectively query heterogeneous geographic data on a portable device, has high query efficiency and is especially applicable to outgoing engineering personnel.

Description

technical field [0001] The invention provides a geographic data query system and method, especially a query system and method based on heterogeneous geographic data. Background technique [0002] The popularization of informatization has enabled many enterprises and units to use various types of information systems to solve business needs, and at the same time greatly improve work efficiency. However, due to differences in platforms and databases, it is difficult to efficiently exchange information between data sources, and the problem of "information islands" arises. How to integrate these heterogeneous data sources together to achieve a high degree of information sharing has become an urgent problem to be solved. In the application of geographic information, the purpose of heterogeneous geographic data integration is to integrate isolated heterogeneous geographic data sources together, shield the heterogeneity of systems and models, and make the integrated data achieve a ...
