Beams Close to Nadir.
o Maximum: For Beam Formers – Weakest
Beams Far From Nadir.

isn’t changing due to depth.
• Range: Filter Using Sonar or Laser Range Limits.
Depth Filters - Basic

Over / Under Filter: Called “Filter Overhang and Undercut
Topography” in MBMAX 32. - Very Useful and Safe.

Cloud Popup Calibration
Manual Method. New for HYPACK 2022
• Use Step to change the angle step.
Default = 0.1 degree.
• Use Up/Down to step Pitch, Roll or Yaw
Angle. Or enter an angle then click
Adjust.
The visible cloud will recalculate to show
points with angle changes. Repeat as
often as needed. Then:
• Reset: Resets to the angles you
started with.
• Test OK: Accepts angle changes. The
entire survey will be updated, which you
will see in Survey window matrix
display.
Check the Calibration box to enable cloud calibration.

CUBE in MBMAX64

CUBE
Combined
Uncertainty and
Bathymetric
Estimator
• Intended to Speed Processing of Multibeam Data.
• Developed by Dr. Brian Calder of CCOM-UNH.
• A ‘statistical’ approach to cleaning multibeam data.

CUBE Terminology
Note:
CUBE ‘hypotheses’ are not actual soundings, but are estimates
of depth at each node, based upon the data points in the node’s
neighborhood.
CUBE Node:
• An X-Y point where CUBE will make depth estimates based on the
surrounding data points.
• CUBE Nodes are placed at fixed distances, resulting in a square grid.
HYPOTHESIS:
• A possible depth estimate at a node.
• A CUBE Node can have multiple depth estimates.
CUBE Neighborhood:
• The area surrounding a CUBE Node where depths can influence the
‘hypotheses’

CUBE
Neighborhood
Data Points from HS2 File
• A series of CUBE nodes make a CUBE GRID.
• Soundings about the neighborhood of each node are used to generate possible depth
estimates for the node (Hypotheses).
• If there are multiple depth estimates at a node, CUBE selects one based on your input
parameters.

CUBE in MBMAX 64 – Part 2
CUBE engine will process data. Note the selection for depths now
include depth, uncertainty, count and ratio computed by CUBE

CUBE vs. Minimums and Maximums
 Green: Check Lines Processed in CUBE.
 Black: Processed Only in MBMAX: Sorted for Min and Max.
The HYCUBE surface usually resembles a smoothed median surface.
Do not use CUBE if you
are interested in the
minimum depth over a
rock or obstruction.

FEATURE
DETECTION

Use Tools menu, USACE eHydro.
Easy submission of survey data to eHydro. (eHydro = US Army
Corps of Engineers online survey database)

Survey Naming Support
• Select Project Area, eHydro Area and Survey Type
from drop down lists.
• Each district has it’s own project/area file:
eHydroProjectAreaExport.xml in the HYPACK root
folder.
• Survey Date filled automatically.
• Metadata and Targets are accessed with the buttons.

Limited metadata, the details come from HYPACK logged data.
