Software for Bottom Classification and Sediment Analysis



Comprehensive Seabed Classification Made Easy
This application software utilizes unique template databases to store verified data for future use. Information contained in the stored data files can be displayed without special equipment or additional software. Analysis using VBT-Seabed Classifier gives depth, seabed class, sediment and aquatic macrophyte data. Signals can be automatically geo-referenced with GPS data for output to GIS applications for production thematic map layers.

By correlating data from a reference set of bottom samples - and without special equipment or additional software - BioSonics' VBT-Seabed Classifier™ decodes information about depth, seabed class and sediments embodied in digitized echo envelopes from stored data files.

Flexibility for a Variety of Applications
The VBT-Seabed Classifier™ is designed for use with BioSonics DT-X Series Echosounders.

The output files of the VBT-Seabed Classifier™ are produced in ASCII format in geographical context (Latitude and Longitude). The VBT-Seabed Classifier™ can also be run concurrently with navigation software or with GIS applications to produce thematic charts of bathymetry and seabed classification.



Database Templates for Accurate Seabed Classifying
The VBT-Seabed Classifier™ utilizes a unique method of collecting data in a template database, implementing the following classification methods through classic echo integration without attenuation:

• B2 - First/Second Bottom Ratio
• B3 - First Echo Division
• B4 - Fractal Dimension

Additionally, in the S mode, sediment is visualized by implementing echo integration with attenuation. This mode may be used to estimate the density of aquatic plants or bottom fish which usually attenuate echo signals.
