A mapping method, comprising: a) using a first global positioning system in a first vehicle to determine global position coordinates of a roadway as the first vehicle traverses the roadway; b) using a first two-dimensional intensity field sensor in the first vehicle to create a first two-dimensional map that maps two-dimensional features of the roadway while the first vehicle traverses the roadway; c) using a three-dimensional position sensing device in the first vehicle to sense three-dimensional positions of the two-dimensional features of the roadway while the first vehicle traverses the roadway, wherein the three-dimensional positions of the two-dimensional features include distances between the two-dimensional features and the first vehicle; d) using a first processor in the first vehicle to create a three-dimensional map including associations between the two-dimensional features of the roadway mapped in the first two-dimensional map, the three-dimensional positions of the two-dimensional features of the roadway, and the global position coordinates of the roadway; e) providing the three-dimensional map from the first vehicle to a second vehicle; f) using a second global positioning system in the second vehicle to determine global position coordinates of the second vehicle as the second vehicle traverses the roadway; g) using a second two-dimensional intensity field sensor in the second vehicle to create a second two-dimensional map of the features of the roadway while the second vehicle traverses the roadway; h) matching the global position coordinates of the second vehicle to the global position coordinates associated with the three-dimensional map; i) using a second processor to match the two-dimensional features of the second two-dimensional map with the two-dimensional features of the three-dimensional map associated with the matched global position coordinates; and j) using the three-dimensional positions of the matched two-dimensional features for determining distances of the second vehicle with respect to the matched two-dimensional features of the roadway features, wherein the first two-dimensional intensity field sensor in the first vehicle is in the form of a first camera and the second two-dimensional intensity field sensor in the second vehicle is in the form of a second camera. a) using a first global positioning system in a first vehicle to determine global position coordinates of a roadway as the first vehicle traverses the roadway; b) using a first two-dimensional intensity field sensor in the first vehicle to create a first two-dimensional map that maps two-dimensional features of the roadway while the first vehicle traverses the roadway; c) using a three-dimensional position sensing device in the first vehicle to sense three-dimensional positions of the two-dimensional features of the roadway while the first vehicle traverses the roadway, wherein the three-dimensional positions of the two-dimensional features include distances between the two-dimensional features and the first vehicle; d) using a first processor in the first vehicle to create a three-dimensional map including associations between the two-dimensional features of the roadway mapped in the first two-dimensional map, the three-dimensional positions of the two-dimensional features of the roadway, and the global position coordinates of the roadway; e) providing the three-dimensional map from the first vehicle to a second vehicle; f) using a second global positioning system in the second vehicle to determine global position coordinates of the second vehicle as the second vehicle traverses the roadway; g) using a second two-dimensional intensity field sensor in the second vehicle to create a second two-dimensional map of the features of the roadway while the second vehicle traverses the roadway; h) matching the global position coordinates of the second vehicle to the global position coordinates associated with the three-dimensional map; i) using a second processor to match the two-dimensional features of the second two-dimensional map with the two-dimensional features of the three-dimensional map associated with the matched global position coordinates; and j) using the three-dimensional positions of the matched two-dimensional features for determining distances of the second vehicle with respect to the matched two-dimensional features of the roadway features, wherein the first two-dimensional intensity field sensor in the first vehicle is in the form of a first camera and the second two-dimensional intensity field sensor in the second vehicle is in the form of a second camera.
