  "textContent": "A processing system including at least one processor may obtain a location of a mobile device and a barometric pressure reading of the mobile device, identify a weather reference area and a ground reference area containing the location, and calculate an elevation of the mobile device from the barometric pressure reading of the mobile device and a barometric pressure metric of a weather reference point of the weather reference area, where the weather reference point has a predetermined elevation. The processing system may then determine a height of the mobile device over a ground level of the location based upon the elevation of the mobile device that is calculated and based upon an elevation of a ground reference area containing the location and provide a report of the location of mobile device including the height of the mobile device over the ground level that is determined.",
