Map data processing method, system and mobile terminal based on mobile terminal

Abstract

The invention provides a method for processing map data based on a mobile terminal, a system and the mobile terminal. The method comprises the following steps of: carrying out format conversion processing for the map data and generating map vector data; encoding the generated map vector data and generating the map vector data with a compressed format; constructing a dynamic vector database in themobile terminal; downloading the map vector data with the compressed format into the dynamic vector database; reading the map vector data with the compressed format from the dynamic vector database and decoding the map vector data with the compressed format to obtain the map vector data; and mapping a map which is corresponding to the map vector data on a display of the mobile terminal according to the map vector data and mobile terminal display pixel data. The method, the system and the mobile terminal are used to solve the problem that map data storage is matched with display and real time map scanning, voice navigation, real time geographic information and interest point searching and the like on the mobile terminal are realized in deed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to the storage and display of map data in wireless communication devices, and specifically to a mobile terminal-based map data processing method, system and mobile terminal thereof. Background technique [0002] There are two main types of map storage and display technologies for existing mobile terminals: [0003] 1. All the map image data is stored in the memory card or the local memory of the mobile terminal, and the user program can directly read and display it. The advantage is that the display speed is fast, but the disadvantage is that it occupies too much storage resources of the mobile terminal and the map data cannot be updated in real time. [0004] 2. The map data is stored on the server side of the network, and the mobile terminal can download the required display information from the server side of the network in real time through the wireless co...
