An aerial vehicle equipped with a first range sensor oriented to capture range data above the aerial vehicle and a second range sensor oriented to capture range data below the aerial vehicle is programmed with global map of an indoor space, including an upper global map representing distance data for upper surfaces of the indoor space and a lower global map representing distance data for lower surfaces of the indoor space. An offset to an altitude is calculated based on a comparison between range data captured by the first range sensor and the upper global map, and range data captured by the second range sensor and the lower global map. Additionally, global maps may be updated based on returns captured by the range sensors, where such data indicates the presence of a previously undetected object.
