A good way to measure ground distance is by pace count.
A seismograph is used to measure ground movement or vibrations on the Richter scale.

Pace Count
A seismograph is used to measure ground movement or vibrations on the Richter scale.
A CT is used to measure current, and is NOT referenced to ground, and has very low primary impedance. A PT is used to measure voltage, is referenced to ground, and has a much higher impedance (since it is referenced to ground).
Measure they key, typically found near one of the corners. And then measure it and see how many kilometers/miles it is then measure the distance from your starting point to finishing point and compare it to the key
Measure the ground resistance from the user end point, where earth or ground cable is connected. It will show a very high resistance or open if ground is broken.

Using very sensitive accelerometers.
You cannot measure meat by pints.
You can display ground levels by labeling in legend or, you can add a elevation measure, such as (ground +0,00) ( 1rst floor +3,07) and so on...
