Sensor information is obtained from a downward facing sensor coupled to an aircraft. A new position is determined using the sensor information, including by: obtaining directional information associated with the aircraft's direction of flight, obtaining a previous position associated with the aircraft, filtering a plurality of datasets in a ground feature database using the directional information and the previous position in order to obtain a reduced group of datasets (where each dataset in the ground feature database is associated with a known in-air position), and comparing the sensor information against the reduced group of datasets in order to determine the new position.
