| Bathymetry map example: this image shows a high-resolution 3D map of the sea bottom in the surveyed area. The data was processed using BioSonics Visual Analyzer. |
 |
| Bathymetry map example (close-up): this image shows a high-resolution 3D map of the sea bottom in the region around an underwater rock pinnacle. The data was processed using BioSonics Visual Analyzer. |
 |
| Bathymetry map example (section): this image shows a high-resolution bottom map, of a section of the surveyed area, created using the Kriging gridding method. A color scale indicates depth values. The data was processed using BioSonics Visual Analyzer. |
 |
| Ship-track and Bathymetry example: this image superimposes the 2D ship-track map over the high-resolution 3D bathymetry map of the surveyed area. The data was processed using BioSonics Visual Analyzer. |
 |
| Echo-position example: this image shows the three dimensional fish positions relative to the bathymetry, color-coded by Target Strength. It also includes the 2D map of the ship-track (above). The data was processed using BioSonics Visual Analyzer. |
 |
| Echo-position example (close-up): this image shows the three dimensional fish positions relative to the bathymetry, color-coded by Target Strength. It also includes the 2D map of the ship-track (above). The data was processed using BioSonics Visual Analyzer. |
 |
| Echo-position vs. Depth example: this image shows the three dimensional fish positions relative to the bathymetry, color-coded according to depth. It also includes a sample background image (water simulation). The data was processed using BioSonics Visual Analyzer. |
 |
| Echo-position vs. TS example: this image shows the three dimensional fish positions relative to the bathymetry, color-coded according to Target Strength. It also includes a sample background image (water simulation). The data was processed using BioSonics Visual Analyzer. |
 |
| Complex Symbology example: in this image fish positions are represented as elaborate 3D fish symbols, color-coded according to Target Strength. The purpose of this example is to illustrate how complex symbology can be used to enhance a GIS image. The data was processed using BioSonics Visual Analyzer. |
 |
| Map Overview example: this image shows a geographic 3D map of Kodiak Island, with the surveyed area indicated by a red circle. This example illustrates how geographic map displays can enhance the presentation of analysis results. |

Lake Washington - Sample images
Data collected between March 27th and March 29th, 2001,
using a BioSonics DT multiplexing echosounder system,with a 420 kHz,
6°, single-beam transducer and a 70 kHz, 6°, single-beam transducer.

| Survey Transect example: this image shows a 2D map of the survey transects (50 meters spacing), followed during the collection of acoustic data. Processing of the data was completed using BioSonics Visual Analyzer. |
 |
| Bathymetry example: this image shows a bathymetric map of the surveyed area. Depths are indicated by a color scale. The data was processed using BioSonics Visual Analyzer. |
 |
| SAV Bottom Coverage example: this image shows a 2D contour map of submerged aquatic vegetation in the surveyed area. The color scale represents the percent of bottom covered by plants. The data was processed using BioSonics EcoSAV. |
 |
| Percent Plant BioVolume example: this image shows a 2D contour map of submerged aquatic vegetation in the surveyed area. The color scale represents the rate of change of plant BioVolume. The data was processed using BioSonics EcoSAV. |
 |
| Sediment Classification example: this image shows a 2D contour map of sediment classification in the surveyed area. The data was processed using BioSonics Visual Bottom Typer (VBT). |
 |
| Map Overview example: this image shows a geographic 3D map of the Lake Washington area, with the northern basin indicated by a red square and the survey area in gray. This example illustrates how geographic map displays can enhance the presentation of analysis results. |
