Abstract
Among other things, one or more techniques and/or systems are provided for locating a position within an enclosure. In one example, known global coordinates (e.g., GPS coordinates of latitude/longitude) associated with the position within the enclosure may be transformed into local coordinates (e.g., x/y coordinates) for the position. The local coordinates may be used for tracking a location of the position within the enclosure. In another example, known local coordinates of the position within the enclosure may be transformed into global coordinates for the position, which may be used for tracking a location of the position within the enclosure. In another example, a blueprint image of the enclosure may be used to track a location of the position within the enclosure. In this way, location tracking may be provided for objects within indoor spaces (e.g., a mapping application may track a current position of a mobile device within a building).
