Method for achieving mobile phone terminal map data zooming and dragging display system

Abstract

The invention discloses a method for achieving a mobile phone terminal map data zooming and dragging display system. The method includes the following steps that a city or a region is selected on a human-computer interaction interface; according to a current request command, if the request command is a dragging command, a mobile phone terminal judges whether to directly display map data or re-download the map data according to a display range after the dragging and current internal storage data; if the data are re-downloaded, the mobile phone terminal judges whether to directly read or re-download data from a server according to the data stored in the mobile phone; if downloading is performed, the mobile phone terminal downloads and stores corresponding data according to the current city or the current region; if the request command is a zooming command, the mobile phone terminal judges whether to perform zooming processing or not according to the current downloaded data and the displayed grade of the zooming. The mobile phone terminal obtains the display data and displays the data on a terminal interface. Through the method, a user achieves the zooming and dragging operation of the map data rapidly and conveniently with less network flows.

Description

technical field [0001] The invention relates to a mobile communication technology, in particular to a method for realizing a mobile phone terminal map data zooming and dragging display system. Background technique [0002] In recent years, with the development of technology and tourism, people use mobile maps more and more. Mobile maps have brought great convenience to people's travel, and have also played an important role in people's work (including sales and market development) in different cities. At present, more and more online map query systems have appeared, but this query system is not practical in mobile phones: first, it is troublesome to input URLs, and the operation of Wireless Application Protocol (Wireless Application Protocol, WAP) browsers is relatively difficult. It is complicated and not suitable for many users who are not familiar with the operation; second, there are many advertisements on the browser website and there may be viruses, which may pose a t...

Problems solved by technology

At present, more and more online map query systems have appeared, but this query system is not practical in mobile phones: first, it is troublesome to input URLs, and the operation of Wireless Application Protocol (Wireless Application Protocol, WAP) browsers is relatively difficult. It is complicated and not suitable for many users who are not familiar with the operation; second, there are many advertisements on the browser website and there may be viruses, which may pose a threat to users

Third, the browser needs to refresh the entire page, and the map data is relatively large, wasting a lot of traffic. Now mobile phones also mainly use traffic billing, which also increases the cost of users; fourth, the display of large map data The mobile phone memory occupied is relatively large, which is unusable for some non-smart mobile phones; fifth, the general mobile phone map, zooming needs to download the corresponding level of image data, resulting in excessive traffic, increasing the cost, and the download itself consumes Certain time, inconvenient to use
