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. 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. Key words:Mapinfo9.5 QT/Embedded Electronic map
