Book Synopsis Airborne Laser Hydrography in the United States by : Van K. Nield
Download or read book Airborne Laser Hydrography in the United States written by Van K. Nield and published by . This book was released on 1980 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: Airborne lidar technology is attractive for hydrographic surveying because of its high rate of area coverage coupled will high spatial data density, rapid-response and reconnaissance capabilities, and cost effectiveness. The National Ocean Service (NOS) has been involved in the design, implementation, and testing of such systems in conjunction with NASA, the U.S. Navy, and the U.S. Army Corps of Engineers (USACE) since 1975. Two topics of current interest are 1) the probability of detection of small objects on the sea bottom as a function of their size, and 2) the efficient reduction of the very large data sets to hydrographically representative but much smaller subsets. Results for both of these are reported here.

Book Synopsis The Transparency of Selected U.S. Coastal Waters with Applications to Laser Bathymetry by : Maxim F. Van Norden
Download or read book The Transparency of Selected U.S. Coastal Waters with Applications to Laser Bathymetry written by Maxim F. Van Norden and published by . This book was released on 1979 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The operational effectiveness of airborne laser hydrography systems, considering the optical environment of the coastal waters of Oregon, Washington, and the Gulf Coast states, is examined. The best times of the year are predicted for conducting laser bathymetry, considering the temporal and spatial variability of optical properties due to seasonal effects, and charts of seasonally averaged optical measurements are given. Original formulas to convert beam attenuation coefficients and Secchi depth measurements to irradiance attenuation coefficients are included. The number of irradiance attenuation lengths to the bottom depth (Kd) are used as the indicator to estimate areas where laser hydrography systems would be successful and are shown by season and region. The conclusions of this thesis are that airborne laser hydrography is not practical in the coastal waters of Oregon and Washington, would be practical in limited areas of the western Gulf Coast, and would be very practical in the eastern Gulf Coast area. Along the eastern Gulf Coast a 38,800 sq nmi area, delineated by a Kd = 4 contour, is judged surveyable by laser. (Author).
