Abstract

The map system is composed of pictures of local map, Web pages and computer with file deposited. Whole map is divided to local areas accordingly; and local small pictures are prepared. Hot areas of Web pages or edited programs for events triggered by point-clicking the pointed positions are setup on Web pages of displaying local map. When user browses specific different areas on map. The system uses relation between coordinate and file name to constitute a map Web pages for an area. Point-clicking hot areas distributed on local map or triggering program event on the position of Web page, system displays detailed information related to the position on local map, or enters into prearranged Web page. Through the invention, developer can develop a map system on network without need of database support. Advantages are: visual, easy of maintenance, high expansibility, accurate positioning and quick response.

Description

A kind of Internet map system

Technical field

The present invention relates to a kind of network map system, more particularly, it relates to a kind of reconfiguring by local picture and shows the appointed area map, and realizes the network map system of map location by webpage hot-zone, webpage programmed events.

Background technology

At present, network map leaves a large amount of map vector datas in the large database in mostly, by the programming technique means, obtain constructing map dynamically behind the map datum by inquiring about a certain area coordinate, though this pattern gains universal acceptance, but his shortcoming also is tangible: 1, need the large database support, cost is huge, does not meet cost benefit for simple, small-sized map application; 2, map datum costliness, and be difficult to Dynamic Maintenance; 3, during many people access drawing system, the database access amount is huge, causes server load heavy, and the network bandwidth narrows down.Up to the present, on market, do not see as yet a kind of light-duty, dependency database, user do not make easily, safeguard simple, the location is convenient, map can be infinitely-great the network map system.

Summary of the invention

Purpose of the present invention is exactly the deficiency that overcomes existing map system, provide a kind of light-duty, dependency database, user do not make easily, safeguard simple, locate make things convenient for, map can be infinitely-great the network map system.

Network map of the present invention system, it is made up of local map picture, webpage and the computing machine of depositing these files.At first, whole map is divided according to the part, make local little picture, and showing the trigger event that the webpage hot-zone is set on the webpage of local figure or clicks assigned address with programming, differently graph region according to viewer's appointment, utilize coordinate and local file name relation, the local picture that will belong to this area by web technologies, a regional webpage map is formed in the hot-zone, click is distributed in the hot-zone on the local picture or triggers the program event of this position on the webpage, system will show this place's relevant information of local picture details or enter predetermined webpage.Effective effect of the present invention is: 1, for the viewer: visual in image, accurate positioning, display speed are fast; 2, for the management map person: dependency database, make easily, safeguard simple, extendability is strong, can infinitely greatly make a map, reduce server load greatly, save operation cost.

Description of drawings

Fig. 1 is the thumbnail of the network map of a certain sub-district in the map of Guangzhou;

Fig. 2 is according to importing parameter into, closing the local map of series structure by filename;

Fig. 3 is the displayed map after clicking.

Embodiment

Divide the little local figure of the individual 256 picture numbers * 256 picture numbers in 16 * 16 (=256) (just these 256 abandon to be linked in sequence just can form whole map) with sub-district, Guangzhou map, according to laterally (from 0 to 15), vertically (from 0 to 15) respectively the file name of the multiple of called after 256 (for example 0_0.jpg represents first local little picture in the map upper left corner; 0_1.jpg second little local picture representing first hurdle, by that analogy).Form by one 3 * 3 form of customization on the webpage, each table size all fixedly is 256 picture numbers * 256 picture numbers, hide the form line, the webpage that comprises little local picture is embedded form, and set the webpage hot-zone at the webpage assigned address that comprises local picture, programme by webpage like this, as long as know the position coordinates that needs demonstration, just can compare according to the multiple of coordinate and 256, determine the sub-pages title that this shows these 9 local pictures, by changing the embedded web page title of this grid, can realize that just the mobile of map browse; Click the picture position of appointment, if above the hot-zone of setting or programmed events are arranged, system will linked web pages or display message.

Claims

1, a kind of Internet map system, it is made up of local map picture, webpage, the computing machine of depositing file, it is characterized in that:

(1) map is to be formed by a plurality of dynamic sequential combination of individual sub-pages that comprise local map in the demonstration of webpage.

(2) form on the sub-pages of map except having comprised local map picture, on picture, also be provided with webpage hot-zone, webpage programmed events.

(3) click the hot-zone be distributed on the local picture or trigger this position on the webpage program event, system will show this place's relevant information details or enter predetermined webpage.
