To provide an increase in hydrographic survey resources the Hydrographic Airborne Laser Sounder is being developed by the Naval Ocean Research and Development Activity (NORDA) under the sponsorship of the Defense Mapping Agency (DMA). The HALS system incorporates a pulsed, scanning blue-green laser and will be flown in a helicopter from a survey ship operated by the U.S. Naval Oceanographic Office (NAVOCEANO). Through the use of statistics in post-flight processing the HALS data will meet survey accuracy standards, more than adequate for safe navigation. NORDA will perform a technical evaluation of HALS and then turn the system over to NAVOCEANO for operation in late 1983. (Author)
