A Routing and Distribution Method for Loose Sliced ​​Map Service

Abstract

The invention discloses a routing and distribution method for a loose sliced ​​map service, the steps of which are as follows: 1. Generate a map slice file and publish it to a file server; 2. Configure the code, name, description, area, catalog, and label of the sliced ​​service , coordinate system, prefix, and suffix information; 3. Publish slices through SpringBoot-based Restful services, and output service configuration information; 4. Register gateway services according to distribution rules, configure service names, paths, IDs, regions, labels, and retry , Whether there is prefix information; 5. Distribute services through SpringCloud-based Zuul components; 6. Obtain keys through user authentication, and access service records according to routing and distribution strategies. Through the above method, the present invention solves the problems of lack of self-definition means and unsafe access and sharing in the release and management of loose slice file services.

Description

technical field [0001] The present invention relates to a routing and distribution technology for sliced ​​map services in the field of geographic information, in particular to a light-weight, dynamic configuration and release of sliced ​​map services with a standard loose structure, and access to sliced ​​​​services defined through security authentication and routing rules way to meet the sharing and security requirements of slicing services. Background technique [0002] Sliced ​​map service is used in the map loading and display link of the geographic information industry, especially the application display of the basic base map. It is a map cache service area and has the characteristics of making map and image services run faster and more efficiently. Since the pictures in the tiled map service do not need to be generated by the server in real time, the performance of the server is greatly improved, but at the same time, it also brings problems such as difficulty in cust...

AI Technical Summary

Problems solved by technology

Since the pictures in the tiled map service do not need to be generated by the server in real time, the performance of the server is greatly improved, but at the same time, it also brings problems such as difficulty in customizing the service and low security. The current tiled map service relies on professional GIS servers. Publishing makes the original simple file access service must be published through a complex service container, which increases the implementation cost and brings the invisibility of control. Therefore, a lightweight self-publishing tile map service mechanism is urgently needed , while meeting the routing rules and distribution policy control requirements for services

[0003] At present, the existing sliced ​​map services are mainly released by the mainstream ArcGIS Server or the open source GeoServer, and the degree of dependence on them is relatively high; or the service is released in a customized form, lacking effective monitoring and management measures, resulting in the outflow of sliced ​​data Misuse with slicing services
