Navit is a open source (GPL) car navigation system with routing engine. It s modular design is capable of using vector maps of various formats for routing and rendering of the displayed map. It s even possible to use multiple maps at a time. The GTK+ or SDL user interfaces are designed to work well with touch screen displays. Points of Interest of various formats are displayed on the map. The current vehicle position is either read from gpsd or directly from NMEA GPS sensors. The routing engine not only calculates an optimal route to your destination, but also generates directions and even speaks to you.

以前一直在做AO相关的工作，现在转向AE。虽说，AE与AO的语法接近，但是在入门的时候还是比较不好下手的。经过两天的努力，终于在ESRI中国社区上找到一个关于建立ArcEngine的帖子，写得相当详细。根据该帖我终于建立起了一个框架
