A system is provided for determining a location of a landmark for use in navigation of an autonomous vehicle. The system includes a processor programmed to receive a measured position of the landmark. The processor is also programmed to determine a refined position of the landmark based on the measured position of the landmark and at least one previously acquired position for the landmark. The measured position and the previously acquired position are determined based on acquisition of an environmental image associated with the host vehicle, analysis of the environmental image to identify the landmark, reception of global positioning system (GPS) data representing a location of the host vehicle, analysis of the environmental image to determine a relative position of the identified landmark with respect to the host vehicle, and determination of a globally localized position of the landmark based on the GPS data and the relative position.
