Everyone -

What's the commonest way of measuring wave height electronically
(apart from satellite) for the likes of ships, oil rigs and
harbourmasters? A friend of mine needs to measure wave height / sea
height from the side of a harbour and use the output (RS232 / RS485
over radio modem) to control the lighting on the side of a building!
