A method for real time display of maintenance device location in an internal space includes a real time location display. An inspection window includes the real time location display, an observations spreadsheet, and a distance display. If the maintenance device is a video camera, a video screen is also included in the inspection window. The inspection window is displayed on a computer monitor. As a video camera is moved through an internal space, a video signal and distance signal are sent to a computer. Location display software on the computer receives the distance signal and provides a real time location display of the distance that the video camera has traveled. The observations spreadsheet enables an operator to enter information concerning a particular distance measurement of interest and which is also shown on the real time location display. The video screen displays real time video camera feed.
