Regular gridded surfaces are georeferenced images that can contain a visual representation of horizontal and vertical uncertainty.
A surface is saved as a CSAR file, using the CARIS Spatial ARchive framework. This file contains the data and metadata for the surface.
These regulate gridded surface types can be created:
• Swath Angle Weighting uses a weighting scheme based on a beam's intersection angle with the seafloor.
• Shoalest Depth True Position stores the shoalest depth within a given node in the depth layer. The true position of this depth is also stored.
• Uncertainty Weight uses a weighting scheme based on depth uncertainty as specified by a selected S-44 survey order.
• CUBE (Combined Uncertainty and Bathymetry Estimator) surfaces use multiple hypotheses to represent potential depth variances along the seafloor (seeOverview of CUBE Processing.
