摘 要
人们生活质量不断提高，城际间的往来更加频繁，导航仪成为了生活中不可缺少的部分。电子地图是导航仪最主要的部分，而电子地图的绘制工作颇为繁琐，价格也比较昂贵，给导航仪的开发带来了很大的麻烦。如果掌握了电子地图的绘制方法，那么不仅带研发上具有重要意义，而且将带来更大的经济效益。就此，本课题对电子地图的绘制和相关程序的编写开展了研究。
课题对Trolltech公司的QT/Embedded的深入分析和研究的基础上，开发了基于Intel Pxa270的电子地图。地图的数据来源于实际，利用Mapinfo9.5自主绘制电子地图。通过QT的API与Mapinfo图表数据结合，把地图显示在QT的程序框架上。进而进行了相关的功能的设计，主要包括地图引擎的设计、路径规划设计、实时定位设计等。

QT-based Design and Implementation of Electronic Map
ABSTRACT
People constantly improve the quality of life, inter-city exchanges between the more frequent, navigation has become an indispensable part of life. Navigation electronic map is the most important part, the electronic map will work quite complicated, the price is also more expensive, to navigation systems development is a big trouble. If the master electronic map drawing method, then not only with research and development of great significance, and will bring greater economic benefits. In this connection, the subject of the e-map rendering and related research carried out the preparation procedures.
汽车导航仪 Subject to the Trolltech's QT / Embedded-depth analysis and research based on the development of a digital map based on Intel Pxa270. Map data from the actual use of Mapinfo9.5 own digital maps drawing. QT's API through the chart data combined with Mapinfo, the map shows the procedure in the QT framework. Then carried out the functions related to the design, including the design of the engine map, path planning, real-time location and design.
