Embodiment Construction

[0035] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] Before describing the specific embodiments of the present invention, in order to make the scheme of the present invention more clear and complete, at first the abbreviations and key term definitions that appear in the present invention are explained:

[0037] Tile map service request: When using the map service, the user sends an Http request to the map server to obtain pictures of a certain range at a specific scale.

[0038] Spatial overlay method: It is a well-known method in the field, mainly used for comprehensive analysis of multiple thematic layers, and is a traditional spatial analysis method determined by the regional and multi-level characteristics of GIS.

[0039] Such as figure 1 As shown, the present invention provides a tile map service method, comprising the following steps:

[0040] S1: Use the gateway interceptor to capture user...

Abstract

The invention discloses a tile map service method. The method comprises the following steps: S1, capturing a user request by using a gateway interceptor, and matching the user request belonging to a tile map service request according to a map gateway rule; S2, analyzing the user request belonging to the tile map service request, extracting a spatial range and user information of a tile map, and completing tile map service according to the spatial range and user information of the tile map. According to a tile map service gateway method based on regional application and user authorization, authorized access of the tile map service is achieved on the premise that the existing tile map service is not changed, and therefore, the tile map service gateway method is flexible in process and good in compatibility and portability; in combination with a gateway technology, information of a rear-end map server is shielded, so that data security is improved, and potential safety hazards such as unauthorized application and data leakage of tile map services are solved.

Description

technical field [0001] The invention belongs to the technical field of tile maps, and in particular relates to a tile map service method. Background technique [0002] Tile map service refers to the tile map service specification in accordance with the Open Source Geospatial Foundation (Open Source Geospatial Foundation, a global non-profit organization whose goal is to support global cooperation, establish and promote high-quality spatial information open source software) , providing users with a standard on-demand access map service, which makes the front-end access faster, the back-end server consumes less, and the user experience is better. In the existing tile map service, all users can use the global map, which leads to security risks such as unauthorized application of information and data leakage. At present, there are two commonly used solutions. One is to release tile map services separately by region, and the other is to transform the existing technology implemen...
