    Abstract: Systems and methods for navigating a host vehicle are disclosed. In one implementation at least one processor is programmed to receive at least one image captured by a camera from an environment of the host vehicle; analyze the at least one image to identity a representation of a lane of travel of the host vehicle along a road segment and a representation of at least one additional lane of travel along the road segment; analyze the at least one image to identify an attribute associated with the at least one additional lane of travel; determine, based on the attribute, information indicative of a characterization of the at least one additional lane of travel; and send the information indicative of the characterization of the at least one additional lane of travel to a server for use in updating a road navigation model.

    Abstract: A navigation system may include a processor programmed to analyze a first image to identify a non-semantic road feature; identify a first image location, in the first image, of one point associated with the non-semantic road feature; analyze a second image to identify a representation of the non-semantic road feature in the second image; identify a second image location, in the second image, of the one point associated with the non-semantic road feature; determine, based on a difference between the first and second image locations and based on motion information for a vehicle between a capture of the first image and a capture of the second image, three-dimensional coordinates for the one point associated with the non-semantic road feature; and send the three-dimensional coordinates for the one point associated with the non-semantic road feature to a server for use in updating a road navigation model.
