Abstract:

Conventional waterborne hydrographic survey methods have become exceedingly expensive while the need for improvement of charts is increasing rapidly. The U.S. Government is developing techniques to conduct rapid, efficient surveys especially airborne laser bathymeters. The first system should be in use by 1983. It will penetrate to 28 meters under typical conditions and will be deployed in a helicopter from a coastal survey ship. A hybrid system using a combined laser and multispectral scanner is also under development for surveying clear, shoal areas. Advanced high pulse rate laser systems are also under study. Author
