Abstract: Aspects of the present disclosure provide techniques for determining floors at a geographic location using barometric air pressure sensors in a mobile phone. An exemplary method includes identifying a first height associated with a location based on a client device. The first height indicates an entry level of the client device at the location. Using information regarding an amount of outside air pressure at the location, a pressure sensor in the client device is calibrated. A pressure offset for the location is calculated. The pressure offset identifies a difference between air pressure readings inside the location and the amount of outside air pressure at the location. Using the calibrated pressure sensor, a second height associated with the location is determined based on readings from the calibrated pressure sensor and the pressure offset. The second height indicates a different level at the location that the client device is currently on.
