About surfaces
Surfaces can be viewed on multibeam echograms, the dataflow window and scenes. Surfaces can be used to represent a detected bottom (new surface) or a specified bathymetric surface (virtual surface). You can exclude samples from analysis above or below a specified surface.

Surface support includes:
- Coloring a surface using a raster image
- Create a virtual surface
- Preview bottom sample data
- Detect a surface on a multibeam echogram
- Exporting multibeam bottom preview samples
- Export a surface
- Import a surface
- Resample a surface
- Specify Exclude surfaces and other Surface exclusion
- View a surface on a multibeam echogram
- View a surface on a scene
Notes:
- The geographic positions of the bottom detection from which the surface is created are corrected for transducer geometry. As a result, the surface properties and position in the scene represent real world coordinates.
- The Processed data operator accepts multibeam operands and applies Exclude above and Exclude below surfaces.
