an interactive software application employs visual confirmation of location information to construct visual routes on a map without the need for separate location - measuring devices . this enables the recording of tours of interiors or other locations where conventional location data such as from a gps system is unavailable , and the use of even inaccurate or arbitrary maps . the preferred embodiment uses panoramic or immersive motion picture tracks because they contain the most comprehensive amount of information about the location . in drawing the routes of the movies on a floor plan , the user starts with the image of a location to confirm the starting point , then establishes keypoints along the way , locking selected time points of the movies to spatial locations in the map . other controls change the shape of the routes on the map , or the rate of travel between the keypoints . the result is an interactive , comprehensive tour of a space that can be packaged as an interactive project for distribution locally or as a web service .
