1. MATRIX REPORTER HYPACK & DREDGEPACK 2013

2. Purpose of the MATRIX REPORTER To provide a quick report of progress in any dredging environment. To allow the user to see where the dredging has occurred with a visual representation.

3. MATRIX REPORTER The MATRIX REPORTER program is located in the menu under UTILITIES – DREDGING UTILITES. When the program starts it inherits the background display from the main HYPACK Shell program. There are no options to manipulate what is displayed within this program. The tool bar does allow the user to manipulate the display with zoom, pan, and rotation.

4. At the beginning of the project the user opens the pre-dredge matrix to create a base record of the project. All of the data is stored in a file with the same name as the matrix, the extension is changed to.mtd Updates can be loaded at any user desired interval. Each update is loaded with the date of the computer when it is loaded. The user can change the name and the color of each update. MATRIX REPORTER

5. To load an update the user selects the third icon on the tool bar and selects the matrix to add. The update must be from the same source matrix parameters. This means that the corner, size and cell size must all be exactly the same. The program will not remap data from a matrix that does not have the same header. Once the update has been added to the database, the cells that have been changed will appear in the map area. MATRIX REPORTER

6. To change the color or the date the user can choose the fourth icon on the tool bar. The Manage Updates dialog appears and the user can add a title to the page, change the color of any update, change the date of any update or they can turn off any update. When an update is turned off in the Manage Updates dialog it will not display on the map but the Total Material Removed Estimate will include all of the dates in the database. MATRIX REPORTER

7. In this image there are 5 updates loaded but the update for 9/1/2010 has been disabled. On the bottom of the Approximate Material Removed section you will notice that there is an asterisk next to the total value. This is the indication that the sum of the values you can see are not going to equal that total value because there are updates not visible. The program limits this section to the last 10 updates even if they are all enabled. MATRIX REPORTER

8. The Approximate Material removed is not a volume. It is an estimate of material that was removed in a perfect vacuum if the matrix cells were dredged exactly to the depth that the dredging tool was lowered to in the cell and that there was no movement of material on the bottom after the tool was lifted out of the cell. To make this perfectly clear… THIS SHOULD NOT BE USED FOR VOLUME QUANTITIES OR ESTIMATES. MATRIX REPORTER
