Problems solved by technology

[0004] Embodiments of the present invention provide a method and device for providing map services, which are used to solve the problem that the existing map service providing methods put a lot of pressure on the client, and the application area is relatively narrow, or put a lot of pressure on the server, resulting in slow response speed of the server. The problem of low access efficiency

Embodiment Construction

[0044] In the embodiment of the present invention, the vector data file of the map is hierarchically cut into different vector tile files at the network server end, and the map tile display is completed by loading the vector tile files at the browser end; adopting the embodiment of the present invention , the client operating system can realize the drawing and display of map tiles without installing specific software or browser plug-ins. In addition, although the data needs to be obtained from the network server, only the actual required vector tile files need to be loaded, that is, the entire Part of the vector data of a map is enough, which greatly reduces the burden on the network server and improves the loading and display efficiency.

[0045] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0046] like figure 1 As shown, it is a flow chart of the map service providing method provided by Em...

Abstract

The present invention relates to the technical field of a computer network and particularly relates to a map service providing method and apparatus for solving the problem of low response speed of a server, which is caused by a high pressure of an existing map service providing method on a client or a server side. An embodiment of the present invention provides the map service providing method which comprises: a user terminal determines a map segment requesting message input by a user through a browser; the user terminal, according to the map segment requesting message, requests a network server for a vector tile file corresponding to the map segment requesting message, wherein the vector tile file is a vector data file of a map tile and the map tile is a map segment in a set cutting hierarchy corresponding to the map segment requesting message after the whole map is cut according to different cutting hierarchies; and the user terminal draws and displays the map tile according to the vector tile file sent by the network server.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for providing map services. Background technique [0002] With the continuous development of computer networks, map services are also widely used. The existing map service provision methods mainly include two structural forms, one is the client / server (Client / Server) structural form, under this structure, the client supports the map service by installing a dedicated client software Provide functions, with the characteristics of fast response and high security. Although this method can give full play to the processing performance of the client, it has obvious disadvantages such as narrow application range, fixed user group, and high development and maintenance costs. The other is the browser / server (B / S) structure. Under this structure, system users access the corresponding Web Geographic Information System (Web Geography Information System) by input...
