Abstract: Systems, methods, and computer storage mediums are provided for positioning image markers on a virtual canvas. An exemplary method includes positioning one or more virtual objects on the virtual canvas. Each virtual object corresponds to a physical object located within the physical space. The position of each virtual object on the virtual canvas approximates the location of its corresponding physical object within the physical space. A plurality of image markers are also positioned on the virtual canvas. Each image marker's position on the virtual canvas corresponds to a physical location within the physical space where a photographic image's photo capture device was located when the photographic image was captured. A link between a first image marker and a second image marker is also created. The link indicates a path, traversable by a user, within the physical space between the physical locations represented by the first and second image markers.
