Modifications And Improvements To The Sea Beam System On Board R/V Thomas Washington, Christian De Moustier, T Hylas, J C. Phillips
Center for Coastal and Ocean Mapping
A number of modifications to the narrowbeam echo-sounder and echo processor of the Sea Beammultibeam bathymetric survey system have been implemented. These include the design and construction of a digital pitch compensator, the ability to use a variety of sensors for vertical reference, the design and construction of hardware test equipment, and an interface to the shipboard DEC VAX-11/730 computer for data logging, automation of start-up procedures, and performance monitoring
State Of The Art In Swath Bathymetry Survey Systems, Christian De Moustier
State Of The Art In Swath Bathymetry Survey Systems, Christian De Moustier
Center for Coastal and Ocean Mapping
In the last decade, advances in real-time computing and data storage capabilities have led to significant improvements in bathymetric survey systems and the single point echo-sounder has now been replaced by a variety of highresolution swath mapping sounding systems. This paper reviews the state of the art in the non-military swath bathymetry mapping systems. Such systems are typically multi narrow beam echo-sounders or interferometric side-looking sonars with swath width capabilities ranging from 0.75 to 7 times the water depth. The paper compares the design characteristics and the echo processing methods used in a number of these systems manufactured in Japan, …
Using The Bat: A Six Dimensional Mouse For Object Placement, Colin Ware, Danny R. Jessome
Using The Bat: A Six Dimensional Mouse For Object Placement, Colin Ware, Danny R. Jessome
Center for Coastal and Ocean Mapping
Placement in space is inherently six dimensional. An object can be translated in x, y and z cartesian coordinates, and it can be rotated about three axes to change its orientation. A six dimensional sensor I\I(/S conj/gured as a one button six dimensional mouse (which we call a bat) and interfaced with an IRIS workstation thus creating an environment for investigating the problems of object placement. A sojiware workbench was built which allows the manipulation of hierarchical scenes displayed on a monitor. The features of the workbench are described together with experiences using the bat in a variety of interaction …
