Abstract

The present invention provides a geographic information data distribution service method and system. The system for executing the method includes more than two data centers. The method includes: packaging the geographic information data collected by the system to generate a grid data package ; According to the data demand directory of each data center, the grid data packet is sent to the corresponding data center; the dynamic domain name service device receives the geographical information service request sent by the user, and redirects the geographical information service request to the corresponding user The data center with the highest internet connection speed requested. The invention solves the concurrency bottleneck problem caused by the wide-area complex network environment existing in the single data center scheme of the traditional geographical information Web service through the data distribution mode of the distributed multi-data center.

Description

technical field [0001] The invention relates to the technical field of geographical information data services, in particular to a geographical information data distribution service method and system. Background technique [0002] Geographical information Web service is a group of functional entities related to geographic information in the Internet environment, which exposes encapsulated functions through its calling interface. The existing geographic information service (GIS, Geographic Information System) includes GIS data service and GIS function service. GIS data service provides spatial data through interface, and GIS function service provides spatial data processing function through interface. [0003] With the maturity and development of spatial information technologies and industries such as location services (LBS, Location Based Service), high-resolution satellite remote sensing, and street view services, the speed of spatial information collection has been greatly ...
