Problems solved by technology

[0004] In the prior art, since map drawing and thematic maps are completed on the server side, in the concurrent access webGIS software architecture system, it is easy to increase the computing load of the server, and the amount of data transmitted by the network is large, resulting in the response speed of the drawing. slow
At the same time, the thematic maps produced by these WebGIS software are sent to the client in the form of a picture, and the interactivity is poor.

Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the present invention, but not to limit the scope of the present invention.

[0035] figure 1 It is a flowchart of a network thematic map drawing method according to an embodiment of the present invention, and the flow of the method is as follows:

[0036] In step S1, the client sends a drawing request including drawing parameters to the application server through the network. Cartographic parameters are input on the client, and the cartographic parameters include map name, cartographic layer, theme type and cartographic chart type. When entering the parameters of the cartography chart type, the map name is for the user to choose in the form of a list. Each map name corresponds to a map in the map server. After the map name is selected, the cartographic laye...

Abstract

The invention discloses a network thematic map making method and map making system. The method includes the steps that a client sends a map making request to an application server, and the map making request contains a map name and a map making layer; the application server calls a map server and extracts a map corresponding to the map name and unique identifiers of various graphics primitives of the map making layer of the map; meanwhile, a thematic data server is called, and thematic data corresponding to the unique identifiers of the graphics primitives are extracted; the extracted thematic data are encapsulated into a data file, and the data file, the map and the unique identifiers of the graphics primitives are sent to the client. The client calls a chart plug-in module to analyze the data file to obtain the thematic data so that a chart can be generated, and the chart and the map are displayed in an overlapped mode. According to the method and system, computational loads of the servers in the network thematic map making process are lightened, and the response speed of network map making is improved.

Description

technical field [0001] The present invention relates to Web Geographic Information System (WebGIS) technology, and more specifically relates to a web thematic map drawing method and a drawing system. Background technique [0002] Thematic maps combine spatial geographic data with business thematic data and present them visually and intuitively in the form of maps, realizing the map visualization of thematic data. With the rapid development and application of Internet technology and WebGIS technology, there are more and more applications of web-based thematic maps in various industries of the national economy. In order to meet various application needs, higher requirements are put forward for web-based thematic map drawing. It is mainly reflected in the following three aspects: first, the types and types of thematic maps. Due to the different types of industries, the needs and requirements for the expression forms and methods of thematic data are not the same. Therefore, in...
