bye for today. try to map the bounds of the town to the bounds of the rectangle on your screen. then take the digital data that is set of longitudes and latitudes from ge for some of the roads, i mean take a sample at each road turning, put them sequentially in a file, convert them into pix data, scale them to the square on your screen, plot lines from one point to other. now u will see the map that u have extracted from ge. now you should be able to plot the value you have received from ur usb gps device. all the best bye.

the map which i am using is OPEN STEET MAP, i exported the map and want to have it in my application which reads the .gpx files.
sorry my friend, i really have no idea on the format, which you are using. here, in this thread, we were discussing on creating our own map format and our own map tool. to solve your, problem, you may have to go through the api provided by the map tool which you are using. first let me know, what tool you are using? good luck.

1.does your map tool provide any api or function to plot a latitude or longitude? 2.are you displaying the map on the screen? if so, which control?

your question is clearly not understandable. as far as i understood, you might want to convert x : 1 9 1 1 6 1 to 45°46'47.16" if this is what you want to convert, then, apply a reverse formula you should get it. any problem in getting that, then i can help you.
