For now we have a very simple tract plotter for free use from any computer with a web browser. It works with straight lines only. Calls must be made in the example forms given below, with periods separating degrees, minutes, and seconds; only degrees are required. Each call must be on its own line. Closure will appear as a red line. If your tract isn't plotting correctly, please click here
