There are two main ways of determining altitude: geometric measurement and barometric measurement.
Geometric Measurement
Geometric altitude measurement is typically performed using GPS, although there are other methods which would give the same result. A geometric altitude measurement tells you exactly how far you are from the ground. This is the measurement you would expect to get if you had a very long ruler.
Barometric Measurement
In barometric altitude measurement, we start with a measurement of air pressure.
