Automatic Processing of High-Rate, High-Density Multibeam Echosounder Data [PDF]
, 2003 Multibeam echosounders (MBES) are currently the best way to determine the bathymetry of large regions of the seabed with high accuracy. They are becoming the standard instrument for hydrographic surveying and are also used in geological studies, mineral ...

Echo Sounding and Depths [PDF]
Nature, 1930 IT is to be feared that the note on page 473 of NATURE of Mar. 22 may lead to some misunderstanding and to conclusions unfavourable to the echo method of sounding. Dr. Maurer states that out of 254 comparative soundings made by wire and echo in water over 2000 metres deep no less than 36 showed differences exceeding 100 metres and that the maximum ...

Generalization of Soundings across Scales: From DTM to Harbour and Approach Nautical Charts
ISPRS International Journal of Geo-Information, 2020 This paper presents an integrated digital methodology for the generalization of soundings. The input for the sounding generalization procedure is a high resolution Digital Terrain Model (DTM) and the output is a sounding data set appropriate for ...

Geomagnetic depth sounding in the Northern Apennines (Italy) [PDF]
Earth, Planets and Space, 2014 A Geomagnetic Depth Sounding (GDS) survey covering the Northern Apennines of Italy has been carried out in the period 1992–94. Induction arrows maps and hypothetical event Fourier maps were constructed to obtain an electromagnetic imaging of this area.

The Impact of Acoustic Imaging Geometry on the Fidelity of Seabed Bathymetric Models [PDF]
, 2018 Attributes derived from digital bathymetric models (DBM) are a powerful means of analyzing seabed characteristics. Those models however are inherently constrained by the method of seabed sampling. Most bathymetric models are derived by collating a number

Navigating from a Depth Image Converted into Sound [PDF]
Applied Bionics and Biomechanics, 2015 Background.Common manufactured depth sensors generate depth images that humans normally obtain from their eyes and hands. Various designs converting spatial data into sound have been recently proposed, speculating on their applicability as sensory substitution devices (SSDs).Objective.We tested such a design as a travel aid in a navigation task.Methods.
