ABSTRACT:
A method for surveying, comprising the steps of: video recording all locations to be surveyed from a predetermined control position, for subsequent playback on a monitor screen; preparing a transparent overlay having a scale correlating the predetermined control position of the video recording means with respect to the surveyed locations and the size of the screen; applying the overlay to the screen while playing back the video recording, utilizing the overlay to ascertain actual distances; and, annotating maps or the like with the actual distances, interrupting or replaying portions of the video recording as necessary. In lieu of geometrically correlating the control position, the scaled overlay may be prepared on the basis of at least one actual measurement taken during the course of the survey. The method further contemplates the step of dictating and recording notes pertinent to the surveyed locations and circumstances of the survey, simultaneously with the video recording. The video survey may be conducted from a moving vehicle, such as a motor vehicle, airplane or helicopter, and may be made with a video cassette recording apparatus.
