A pyramid has a rectangular base measuring 6'x4' If its altitude is 8' what is its volume
Altitude. Height. Depends on what you are measuring.
An altimeter is an altitude measuring device (alti + meter).
Yes it is also the altitude and depth

A backstaff is a an early navigational instrument for measuring the altitude of the sun and hence calculating latitude.
We would typically use a sextant to measure the angle of a star above the horizon.
Radar altimeter gets altitude information by bouncing a radio wave off the surface of the Earth and determines the aircrafts altitude by measuring the length of time it takes for the signal to return. Barometric altimeters get altitude information by measuring the barometric air pressure outside the aircraft. Barometric pressure decreases as altitude increases. Radar altimeters will give altitude above ground level while barometric altimeters give altitude above sea level.
A hodograph is used specifically for measuring wind direction and speed at an altitude.
It is a mediaeval instrument for measuring the altitude of the sun and other sky objects, now replaced by the sextant.
