GPS定位数据压缩算法的设计与实现 文章作者：杨宏业 张 跃 为了解决嵌入式GPS车载系统存储空间小、GPS定位数据量大的矛盾，根据GPS定位数据的特 点，提出了专用于GPS定全数据压缩的改进型半字节压缩算法。-the design and implementation of GPS locaton data compression algrithm.author:yanghongye,zhangyao.solve the problem of gps car-carring system with little memory ,while heavy dataload.according gps data s characteristic ,put forward gps-oriented data compression,improved half byte compression algrithm.

本程序分两部分，分别为界面和驱动程序，其中驱动程序为压缩解压缩的核心程序。 开发环境为VC6.0。 界面部分可由crs->ddu->ddu.dsp建立工作组，编译生成的可执行程序为debug中的ddu.exe 驱动部分由crs->驱动->驱动.c编译生成可执行文件。 具体压缩解压缩操作可见《操作手册》。-This procedure was divided into two parts, namely, interface and driver, one of the drivers for the compression of the core decompression procedure. Development environment for VC6.0. Interface may be part of crs->ddu-> ddu.dsp Working Group set up, the compiler generates the executable program to debug the ddu.exe driven in part by crs-> Driver-> Driver. C compiler to generate executable file. Extract specific compression operation can be seen " manual."

一个哈夫曼编码,我是新手,随便做个玩,请大家别笑话我.-a Huffman coding, I greenhorn casually Be play, no one I joke.

RAY压缩是综合统计和字典方法，针对数据库的压缩算法。这个算法是专门针对重复率比较高的数据的压缩算法，有较高的压缩比。如果全部重复，那么它的压缩率是以2为底的对数。可应用于电力系统数据的压缩。-Ray compression integrated statistics and dictionary method, the database compression algorithm. The algorithm is targeted at high repetition rate of data compression algorithm, a higher compression ratio. If all the repeat, then the compression ratio is 2 to the end of a few. Can be applied to power system data compression.

一个压缩率很好的壳！-a good compression ratio shell!
