GPS Visualizer: Do-It-Yourself Mapping

GPS Visualizer is an online utility that creates maps and profiles from geographic data. It is free and easy-to-use, yet powerful and extremely customizable. Input can be in the form of GPS data (tracks and waypoints), driving routes, street addresses, or simple coordinates. Use it to see where you've been, plan where you're going, or simply visualize geographic data (scientific observations, events, business locations, customers, real estate, geotagged photos, etc.).
