Embodiment Construction

[0035] In the following method embodiments, in order to solve the problem that the existing geographic information web services cannot meet the high concurrent service requirements of multi-source massive space, the system adopts a multi-data center architecture to realize data distributed distribution, synchronization and load balancing services.

[0036] refer to figure 1 , showing the flow of the first embodiment of the geographical information data distribution service method of the present invention, specifically including:

[0037] Step S101: Pack the geographic information data collected by the system to generate a grid data packet;

[0038]Step S102: Send the grid data packet to the corresponding data center according to the data requirement catalog of each data center;

[0039] In the above-mentioned data requirement directory, the association relationship between geographic information data and each data center is stored. The geographic information data collected ...

Abstract

The invention provides a geographic information data distribution service method and system. The system for carrying out the method comprises more than two data centers. The method comprises the steps: packaging geographic information data gathered by the system, generating grid data packets, sending the grid data packets to corresponding data centers according to data requirement catalogs of all the data centers; receiving geographic information service request sent by a user and redirecting the geographic information service request to data centers meeting user request and having highest network connection speed, through a dynamic domain name service device. The method solves the problem of concurrence bottleneck caused by wide area complex network environment in a single data center scheme of the traditional geographic information Web service through the data distribution mode of 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 ...
