BALTIMORE, March 27 (UPI) -- U.S. engineers say their wearable mapping system can create physical maps of locations where GPS is not available, such as in underground areas and on ships.
Developed by the Applied Physics Laboratory at John Hopkins University, the Enhanced Mapping and Positioning System captures a floor-plan-style map of an area traversed by a person carrying the portable backpack system, as well as 360-degree photos and sensor readings of the area using a combination of lasers and sensors.
