A system and computer program product are provided for providing location and spatial data about the physical environment. The system is configured to sense a tag provided in the environment by a mobile device; receive data from the tag at the mobile device, the data including location and spatial data relating to the physical environment of the tag; and represent the location and spatial data from the tag by the mobile device. In one embodiment, sensing a tag may include sensing a tag in the form of a machine-readable symbol; and receiving data from the tag receives data by processing an image of the machine-readable symbol by the mobile device. In another embodiment, sensing a tag includes sensing a tag in the form of a transmitter device; and receiving data from the tag receives data by receiving a signal by the mobile device. |
