A mobile device includes a chemical sensor to detect chemicals in the environment in which the mobile device is present. The detected chemicals are analyzed and used to generate a chemical characteristic of the environment. The chemical characteristic of the environment is used to determine location related data for the mobile device. For example, an implemented within or remote chemical characteristic database that stores chemical characteristics associated with location related data may be searched based on the chemical characteristic of the environment to determine the location of the mobile device. The location related data may be a location of the mobile device or assistance data that may be used to assist in generating a more accurate position fix, e.g., using a satellite positioning system. The location related data may simply whether the mobile device is inside or outside or the floor of a multi-floor building.
