1. MATRIX FILES IN SURVEY

2. Sample of AutoMTX Display in SURVEY
The Auto Matrix (AutoMTX) feature in HYPACK only works with multibeam systems. Based on your default size, it automatically tracks the average, minimum and maximum depths, along with the number of samples per cell and the standard deviation in each cell.

User defined MTX files are automatically loaded into HYPACK SURVEY and DREDGEPACK. You have to manually enter them in HYSWEEP SURVEY.
The AutoMTX feature is only available in HYPACK SURVEY. It only works with multibeam data. Give it a try!

4. Matrix (*.MTX) Files in SURVEY
HYPACK SURVEY:
For non-multibeam systems, select the driver that you want to use to paint the matrix cells.
For multibeam systems, the depths for every scan are sent to HYPACK SURVEY via shared memory. (Check the options in HYSWEEP SURVEY-Matrix-Options).
DREDGEPACK:
Select the driver that provides the depth of the digging tool.
HYSWEEP SURVEY depth info is passed automatically into HYPACK SURVEY.

5. Programs that can use a MTX File.
Usage
Comments
MATRIX EDITOR
Creates blank MTX files.
Make sure you designate usage in HYPACK or HYSWEEP!
MAPPER
Can fill MTX files with depths.
Does not ‘infill’ blank matrix cells.
TIN MODEL
Can ‘infill’ blank cells on the interior of the model.
SURVEY
Can update MTX files with depths.
Minimum, Maximum or Latest value. Corrected or Uncorrected depth.
HYSWEEP® SURVEY
Updates MTX with depths to show coverage.
Tracks minimum and maximum depth values in each cell. Tracks 100% or 200% for each cell.
DREDGEPACK®
Updates MTX with depth of cutting tool.
Minimum depth value for ‘depth-based’ projects. Maximum depth value for ‘elevation-based’ projects.
XYZ to MTX
Automatically creates filled MTX file.
TIN MODEL for Dummies.

6. MTX Files in HYPACK SURVEY
These options are available for AutoMTX with HYSWEEP data.
These options are available for User Defined MTX.
This window is available from the Matrix menu item in the main HYPACK SURVEY window.
Specify the size of your default MTX x 1000 is the maximum number of cells per MTX.

7. Matrix Options: Map Window
Using AutoMTX, each Map Window can display different matrix info. Above, the left map window has average depths, while the right map window shows the samples per cell.
The Matrix Appearance window is available from each Map Window’s Matrix menu
All depth displays are now light-shaded. You can see more detail if you increase the Z Scale Factor (vertical exaggeration) and adjust the light azimuth and inclination. (0˚ has the light directly above).

8. HYPACK SURVEY Matrix Options
When using “User Defined” MTX files, HYPACK SURVEY will load those MTX files that have been enabled in the HYPACK SHELL.
You cannot change from “User Defined” MTX files to AutoMTX in a project (or vice versa) without losing the real time view of the previous MTX information.

9. Making a MTX File
SURVEY and DREDGEPACK® can load multiple user-made MTX files.
They are automatically loaded and unloaded in SURVEY based on the proximity of the survey vessel.
If your MTX file has been used in DREDGPACK®
You can right-click on the Matrix Files item in the Project Files listing and tell it to display:
Survey Depth
Dredge Depth
Survey – Dredge Depth.

10. HYPACK HARDWARE: Set “Use for MTX Update”
This must be done for the user-defined MTX files. If you are running HYPACK SURVEY and HYSWEEP SURVEY, the multibeam depths will automatically be used to fill the MTX for user-defined MTXs or AutoMTX.

11. Multiple Matrices in SURVEY
When using User-Defined MTX files, HYPACK SURVEY will load and unload each one, depending on the proximity of the MTX to the survey vessel. In Automatic MTX mode, SURVEY displays a 3x3 MTX grid around the current vessel position when “On-Line”. Users can display all MTX files when “Off-Line”.
