Abstract

Data and information about seabed topography is very important, among others for safety navigation and strategic planning other. This paper describes a combination of multibeam echosoder data and Digital Terrain Model (DTM) methode to seen the appearance of the seabed. Moving average method chosen because it is very suitable to be applied in large number of data multibeam. The end result of the combination of the two methods were the three-dimensional visualization. This method used multibeam echosounder data that has been corrected and begins of formation of gridding that represent values that exist along the lines survey. The value of each gridding will be form distribution value of all sounding data. Shadding relief and wireframe visualization sheet is the key to building a DTM. The process of merging the existing layer is used to saw smooth appearance through the implementation of lighting settings that will produce a better image. A simple analysis slope can be seen by the results of this DTM.
