FAQ
Frequently Asked Questions
An altimeter. Different types include radar altimeters (used on satellites and aircraft), laser altimeters (lidar), and pressure altimeters.
No. 'Altitude' is the height itself. 'Altimetry' is the science or process of measuring that height.
Yes, but it's usually called 'bathymetry' when measuring the depth of the sea floor. Satellite radar altimetry measures the sea surface height, which indirectly informs us about the sea floor and ocean currents.
Almost certainly not. It is a specialised technical term valuable for specific academic, scientific, or aviation-related discussions.
The measurement of height or altitude, especially from sea level.
Altimetry is usually formal, technical in register.
