Help In GPS application

[big_jose]

Hi,
I bought an USB GPS antenna (Amaryllo) to make a simple program in VB 6.0. I have a source code that gives me the latitude, longitude and altitude of my GPS. What I want to do is a GPS Ride Plot in VB 6.0. I want to convert GPS track data (longitude and altitude) into an image file with a plot of the course travelled. Could some one please help me?

Thanks

hi,
i'm a engineering student from india, and im looking forward to develop an application based on GPS, which Amaryallo series GPS unit did you use i would like to buy the unit, it will be a great help if you tell me from where you got it and how you got the source codes for finding longitude and latitude, i've been searching for such an api from a very long time,
Thanking You

My website www.eej.ulst.ac.uk/~ian/modules/EEE348J1/vb/gps/ has a VB program I wrote to do this its is called gpsread.zip

GPS outputs are usually simple serial RS232 at 4800 baud, GPS data is sent as lines of text with a simple format defined by the NMEA specification.

USB to serial port covertors can be accessed from VB by accessing the correct COM port, some convertors map onto COM port 13, but if you examine "My Computer" you should be able to find it. Some drivers allow remapping the port to COM1 or COM2, this can be useful for some GPS charting programs that can only use 1 or 2.

The software seaclear is free and allows you to scan in your own maps.

A student of mine has completed a big VB project to allow the same functionality, and can run a scanner directly (twain interface). If I can find his CD I'll upload it.
