最短路径分析的控件,首先使用regsvr32 程序注册该动态连接库,然后在vb中直接使用该动态链接库.程序中有相关说明,具体文件可以查看相关程序.-shortest path analysis controls, the first to use regsvr32 procedures for the registration of the dynamic link library, and then vb direct use of the dynamic link library. Procedures are related note, can view specific documents related procedures.

自己编写的对于NMEA0813解析的C#代码，提供对GPGGA，GPRMC数据的解析-I have written for NMEA0813 resolution C# Code, provide GPGGA, GPRMC data analysis

gps的开发程序，出自吉大的高手，gis开发是目前非常有前途的一个方向。-the development process, from the Kyrgyzstan big players and gis development is a very promising direction.

基于arduino的GPS地图导航系统 SPI接口。采用Atmega 328为主控芯片 需要采用滤波算法过滤 串口速率与GPS模块要设置一致，接线方式如下： //TFT SDA -> UNO 11 //TFT SCK -> UNO 13 #define TFT_CS 10 // Chip select line for TFT display #define TFT_A0 9 // Data/command line for TFT #define TFT_RST 8 // Reset line for TFT (or connect to +5V) #define TFT_LED A0 #define SD_CS 4 // Chip select line for SD card //SD MISO -> UNO 12 //SD SCK -> UNO 13 //SD MOSI -> UNO 11 //GPS tx - UNO rx //GPS rx - UNO tx #define BTNZOOMIN 2 #define BTNZOOMOUT 3
