How to Calibrate an Altimeter

In order to calibrate the altitude of an object you need an altimeter. Calibration is the process of determining the specific adjustment needed to get an accurate measurement. A calibrated altimeter is used to aid in the flight of planes and the distance above sea level. Altimetry is the measurement of altitude and bathymetry is the measurement of depth underwater.
