Problems solved by technology

This method has very high requirements on the performance of the background server, and at the same time, the subsequent processing of map pictures requires a lot of calculation and time.
At the same time, it is difficult to cache the map in the user's local area in this way, so that every time the user requests a map, it must be submitted to the background server, and a new map will be regenerated and then returned to the front page. ideal
Especially for users, the map seen on the front page has no continuity, which is not conducive to user operations

Embodiment Construction

[0042] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0043] see figure 1 and figure 2 As shown, the method for generating and displaying an electronic map based on Flash technology on the computer includes a foreground client, a background server and a map server connected sequentially through the network, wherein the method includes the following steps:

[0044] (1) Divide the map information into a plurality of map slices according to the preset division rules. The division rule of the map slices is: divide the entire map with a fixed size in both vertical and horizontal directions, wherein the map slices The size is 1 / 9 to 1 / 4 of the area of ​​the map visible area in the Flash display interface of the front-end client. The storage mode of the map block information is a picture, and its attribute value includes the map block name, picture position information, scale information and The ba...

Abstract

The method comprises: dividing the map information into map blocks to store in the server; calling opposite block information according to user operation, buffering the block, and displaying the information on bottom map; deciding whether user operation needs new block; moving the block information or calling new block to buffer and display. This invention has ideal display effect, reduces system and network load, and has wide application.

Description

technical field [0001] The present invention relates to the field of Internet Geographic Information Services (Internet GIS: Internet Geographic Information Services), in particular to the field of generation and display of electronic maps, specifically a method for generating and displaying electronic maps based on Flash technology on a computer. Background technique [0002] The unprecedented development of the Internet has made electronic map search a widely developed function for users at all levels. Users can search, map and operate geographic information data directly through the browser. Users can easily find addresses and walking, bus or driving routes through the electronic map, which greatly facilitates users to find addresses and roads. Users no longer need to look up the location of a certain address or the way to go on a certain road on a huge paper map. [0003] Among the current Internet electronic map functions, the user submits a map query request to the b...
