一种基于SQLite数据库的嵌入式瓦片地图绘制方法

An Embedded Tile Map Drawing Method Based on SQLite Database

嵌入式环境存在存储空间小、内存低、计算速度慢的缺点,如何在嵌入式环境下快速绘制地图以及要素标注信息,就成为一个亟待解决的问题。该文基于SQLite数据库设计了一种瓦片地图的存储绘制方法,实现瓦片地图以及要素标注信息的快速绘制。实验表明,该方法具有良好的地图绘制效果,可以满足嵌入式系统实时性的要求。

The embedded environment has the disadvantages of small storage space,low memory and slow calculation speed.How to draw maps and feature information in the embedded environment quickly,has be come an urgent problem to solve.This paper designs a method to store and draw tile maps based on SQLite database,to realize draw tile map and element information quickly.The experimental results show that this method is good of effects and efficiency to meet the demand of real-time in Embedded system.
