Google has invited “citizen cartographers” to refine the U.S. map for Google Maps and Google Earth, using Google Map Maker to ensure the places you care about are richly represented on the map.

Google Map Maker lets you add places, “lines” (like railroads or back alleys), and “shapes” (like a parking lot or Laundromat) to a map. Google has also embedded street-level images from Street View directly into Map Maker for easier navigation.
