摘要
随着智能车辆定位导航系统(IVLNS,intelligent vehicle location and navigation system)的应用日益广泛,但是该格式地图无法在IVLNS中直接使用,必须解析使用。如何在导航系统中应用MAPINFO格式地图数据成为紧迫的问题。针对该格式地图的解析及地图数据的提取,提出了一种在Linux操作系统C编译环境下,由MAPINFO地图转出文件(*.mif和*.mid文件)得到地图数据的方法。详细介绍了其转出的MIF地图格式和地图解析程序的设计所涉及的关键技术。应用本方法编写的程序具有可移植性好,效率高的特点。并且实际运行中效果良好。
With the intelligent vehicle location and navigation system（IVLNS） becomes more and more widely available, but this format map can not be used in IVLNS directly, and it must be analysed before use, how to apply MAPINFO format map data to IVLNS becomes urgent. Against the analysis of this format map and extracting the data, the methods of extracting data from the roll-out file of MAPINFO format map（ ＊. mif and ＊ . mid file） based on the Linux operating system C compiler environment is proposed. The format of its roll-out file（ MIF format map file） and the key technique involved in the map analysis procedure design is described. The preparation procedures which use the method above has the characteristics of portability and high efficiency, and actually runs well.
