LADS

n. young boy, male child; man; fellow

LADS is an acronym for Laser Airborne Depth Sounder.Until recently, a large proportion of waters around Australia had not been accurately charted, because nautical charting is very slow, laborious and time consuming. This is where a ship sails through the waters with depth sounding equipment and records the depth of the water under its path. This means that the set of readings are along a linear track. It can also be a dangerous exercise having a ship sail through uncharted waters.
