1. A method of obtaining digital images related to geographic locations, the method comprising: providing a moving vehicle having thereon a computer having a computer clock interconnected with a GPS transceiver and distance measurement structure configured to measure a distance traveled by the vehicle, the distance measurement structure comprising a pair of laterally spaced apart independently rotating wheels, the wheels spaced apart by a track width, the distance measurement structure simultaneously providing wheel speed measurements from each wheel, the wheel speed measurements and a diameter of each wheel being used to calculate a distance traveled by each wheel, the computer operatively interconnected with a digital camera having a camera clock mounted on the vehicle; receiving into the computer a first geographic position from the GPS transceiver; receiving into the computer a measurement of distance traveled by the vehicle relative to the first geographic position from the distance measurement structure; selecting a pre-determined distance based on a distance between a subject of a photo to be acquired and the camera; determining when the pre-determined distance has been traveled by the vehicle based on the measurement of distance; generating a photo request using the computer on the vehicle for the digital camera on the vehicle at the pre-determined distance, the photo request having an associated photo request time comprising a computer time value obtained from the computer clock, the photo request resulting in a shutter release by the digital camera; taking a digital photo using the camera on the vehicle based on the shutter release, the digital photo having an associated photo time comprising a camera time value obtained from the camera clock; repeating the steps of receiving into the computer the measurement of distance traveled by the vehicle, determining when the pre-determined distance has been traveled, generating a photo request using the computer resulting in a shutter release by the digital camera and taking a digital photo using the camera on the vehicle based on the shutter release; receiving into the computer a second geographic position from the GPS transceiver; storing the photos, associated photo times, photo requests, associated photo request times, first and second geographic positions and distance measurements; conducting a post-processing step remotely from the vehicle, the post-processing step comprising calculating a difference in the distance measurements from the two wheels; calculating a change in vehicle orientation based on the difference; using the change in orientation and distance traveled, iteratively fitting a plurality of path segments, each having a fixed length corresponding to the pre-determined distance and having an associated vehicle orientation comprising the direction in which the vehicle has turned and the number of degrees in the turn, to a path traveled by the vehicle between the first and second geographic positions, the path iteratively fit in three dimensional Cartesian space by an error minimization solver using at least i) the diameter of each wheel or the ratio of the diameters of the two wheels, ii) the wheel speed of each wheel, iii) the track width, iv) the three components of an initial position in the Cartesian space corresponding to the first geographic position, and v) an initial heading of the vehicle; associating each photo with the photo request used to generate that photo by comparing camera time values of a plurality of photos with computer time values of a plurality of photo requests using a piecewise affine transformation; determining a computer time value associated with each photo based on the computer time value of the photo request plus a lag value that accounts for time differences between the generation of the photo request and the taking of the photo, the lag value quantified by comparing camera time values of a plurality of photos with computer time values of a plurality of photo requests; obtaining a location of each photo on the path based on the computer time value of the photo; and, correcting each photo to a rectilinear perspective based on the associated vehicle orientation of the path segment corresponding to the photo and a field of view of the lens to provide a centered perpendicular image orientation for the photo.
