1. An autonomous vehicle comprising:
a velocity sensor;
a radar system;
a digital storage medium; and
a controller in communication with the digital storage medium, radar system, and the velocity sensor, the controller:
retrieves map data from the digital storage medium;
receives current radar data from the radar system;
receives autonomous vehicle velocity data from the velocity sensor;
identifies radar data points in the current radar data that represent objects in motion;
removes radar data points from the current radar data that represent objects in motion; and
matches the radar data with the map data to return location data.
