Features of bathymetric module

The bathymetric module allows you to make full use of Echoview's line creation, editing and export functions.
 

How lines are used

Lines are used extensively in the display, analysis and exporting of data in Echoview. For example:

• Displaying sounder detected bottom line.
• Picking bottom lines.
• Setting 'exclude data above' and 'exclude data below' lines to selectively omit data from analyses and exports, e.g. to exclude surface noise and bottom data.
• To assign a status to pings that intersect with the line for the purpose of including or excluding data from exports and analyses
• To create visual cues on echograms
• To allow exporting of line data for manipulating in other programs
• To import lines from other programs for display on echograms

Key features

• Lines can be created by freehand drawing or by defining them relative to another line or at a fixed depth.
• Virtual lines (lines that maintain a dynamic link to another line) can be created.
• Bottom lines can be picked using a number of configurable algorithms.
• Lines may be edited by manually redrawing them or redefining their properties.
• Manual setting of quality flags (good, bad or unverified) for lines.
• Manual setting of "user defined status" flags (e.g. for bottom-type definition).
• Export of quality controlled depth, position and status information for pings in ASCII format for input into GIS, mapping or other data analysis packages.
• Create 3D digital terrain models of seabeds from lines.
• Import and display 3D seabed surfaces in a variety of formats.
