Applet using a graphical map

I'm working on my first Java project. I need to map various cities on a map of the United States. The cities are static and I will be passing the X,Y coordinates and City name as parameters. Should I be using Latitude and Longitude or pixels to map these points. Once the Cities are in place, I need to draw lines from city to city based upon user selection (I know what lines to draw before I call the applet). This is really another set of Parameters. Can I do this? All I know is that I'll be working with the Java 2-D API. Any advice would be greatly appeciated.

If the cities are static why do you have to pass x, y coordinates in as parameters? If they are static why are their coordinates not just saved statically with the city? Cities do not change location! ( Well, not that often... )

Another thing, I would not use the Java 2D API for this. Personally, I love the 2D API, but for applets it is better to stick with just AWT if you can, because anything added after Java 1.1 requires the user to download the Java 2 Plugin. From what you describe, this program would be no problem with using only AWT functionality.

My first bit of advice is that if you are going to be a mime, you shouldn't talk. Even the tiny ad is nodding:
