Abstract
The hydrography of a land area beneath a shallow body of water is determined by driving a submersible, remotely controlled, powered vehicle along a route over the land area. The vehicle includes a chassis, a drive mechanism, a drive control module to control the drive mechanism, and a mast extending upwardly from the chassis, with the top end of the mast projecting above the body of water. A position indicator, such as a global positioning system, mounted adjacent the mast top end, determines the position of the position indicator, and transmits position data to a receiving unit at a remote location. A transmitter at the remote location transmits instructions to the drive control module to control the vehicle.
