Line of Sight was another very popular interactive map this week which seemed to cover some familiar ground. There are already a number of maps which allow you to track the real-time position of satellites orbiting the Earth. However the futuristic design of Line of Sight seems to have a struck a popular chord.

Enter your location into Line of Sight and you can view the current live position of satellites and their orbital tracks. Therefore you can use the map to find out which satellites might be passing overhead and then go outside and try to find them in the night sky.
