Timber Cruising (EX) Extension Version

Advanced Timber Cruising and Mapping software





Enhancements in the EX version of the CMT Timber Cruising Software

1. Multi-Product Variable-Length Log Data Entry Form

  • You may set up the program to optionally or automatically display the Multi-Product Variable-Length Log Data Entry Form for a Species/Product class. This form lets you enter a number of logs in different lengths. This function is accessed under the “Specify Quantity Computation Methods and Tree Measurement Fields” dialog window. Choose from one of three options to invoke the multi-product option for the specified row:
  • On: multi-product window will always pop-up after key parameters are entered (e.g. DBH and total height) and multi-product information is required.
    Off: multi-product window not available for the selected entry.
    Opt: multi-product window will pop-up after key parameters are entered (e.g. DBH and total height) and multi-product information is optional. The Computation Method must be set to a Stem Profile in order to use the Multi-Product function.
  • The <F3> button can be used to call up the multi-product dialog window manually. You may enter logs of different product classes for the same tree stem. When the Multi-Product Form first comes up, program automatically populates the first log record with the suggested log length for the main product class. You may accept it or change it as appropriate. PC-Cruise verifies each log entry against the product specifications.
  • You may enter a Cull segment between 2 log segments.
  • Unused top portion is lumped as topwood.

2. Reporting Units

  • The program will permit the use of different reporting units for different products within the same stand. Quantities are summarized for each reporting unit.

3. Cruised Plot Indicator

  • The 8th symbol in the CMT Default symbol library is used for displaying the cruised points in Cruise View. This helps you tell at a glance which points have been cruised.

4. Additional Options for 100% Tally

  • When adding stands to be cruised using the 100% Tally method, you may set the tally interval by using the M/C (Measure/Count) ratio field provided on the dialog window.

  • For 100% cruises, you can set the M (measure) option to: 9999 and set the C (Count) field to 0.
    For cruises where all tree will be counted, set the M (measure) option to: 0 and set the C (Count) field to 9999. Built-in options allow for other ratios of measuring to counting to be chosen.

5. Measure/Count Status

  • The M/C count status field keeps track of the total measured and counted trees for the plot.

  • A M/C tool icon is provided to easily switch between the Measure/Count modes for adding a tree.
  • By default this tool is not checked. If the current tree is a measured tree, then marking the box will automatically set the next added tree to be counted. If the current tree is counted, then marking the box will automatically set the next added tree to be a measured tree.

6. Double Point By Tree

  • A variation of the Double Point sampling method has been added. With the Dbl Pnt By Tree method, all trees are counted at each point but only a portion of the trees is measured for volume at each point. In contrast, with the Dbl Pnt By Point method, all trees are counted at each point and, for a fraction of the points, all trees are measured for volume. The Dbl Point by Point method allows you to specify a “Point M/C ratio”.

    Select the desired Cruise Method in the “Add Stand” dialog box:

  • For the Dbl Pnt By Tree method, you may specify a "Tree M/C ratio" (ratio of volume trees to count trees). You may specify "one tree per plot" by setting the M/C ratio to: 1/9999.

7. Pre-Cruise Analysis

    The Pre-Cruise analysis has been enhanced by adding the following fields:
  • "Student t" setting (either 1 or 2)
  • "Population Size (N:)" field for PLOT sampling.
  • Fields to allow for cost consideration in computing optimum sample size.

8. Default VBARs

  • The "Default VBAR" and "Default VBAR 2" setup fields have been added to the merchandise table. They are displayed in the last two columns of the table:

  • For the Dbl Pnt By Point option, the default VBAR will be applied when the calculated "student t" is less than the "critical t". When the correlation criterion is met, then the computed VBAR will be used for reporting the expanded volumes.

9. User-defined data fields

  • You may define your own editable data entry fields at the Tract, Stand, Plot and Tree levels. You may even specify pre-defined data values or drop-down pick lists for these user-defined data fields. These are accessed under the "Specify Quantity Computation Methods and Tree Measurement Fields" dialog window:

  • Click on the button to select the layer that you want to edit. For example, to add a new data field to the initial Tract View screen (containing Land Owner information, etc.), select the “Tract Layer” button. An editor screen will appear which guides you through the process of adding the user-defined fields that you wish to add. The editor is configured in a “wizard” style to make the process easier.

    The Tract, Stand and Plot Layer User Fields Setup dialogs are blank indicating that you can add to these existing screens, but you may not modify the existing fields that are already present.

    The Tree Layer is probably where you will do most of your editing for your data collection needs. The following dialog is displayed when you click on the “Tree Layer” button:

    There are several data fields available for control. The rows highlighted in pink are required fields used by the Cruising software and must be used (i.e. you cannot uncheck the “use” box). However, you may still edit the field names, field width, display order and alignment options for these special fields. Fields may be edited by highlighting the desired field and clicking on the “Edit” button.
After clicking on the edit button, an editor screen will appear which guides you through the process of editing available fields for the user-defined field you are currently editing. The editor is configured in a “wizard” style to make the process easier.

The pick lists for built-in data fields such as: DBH, tree height, #Logs/Sticks, Rep (repetitions or frequency) and FC (Form Class) may be edited.

For example, if you regularly work with DBH = 12, 14 and 16, you may shorten the default list to contain just 12, 14, and 16.

10. Mason Bruce and Girard Volume Tables for 32 ft Logs

  • PC-Cruise now also provides the Girard_Bruce Volume Tables for 32 ft logs. This option can be found under the Mesavage/Girard Table option when specifying the computation method for a species and product.he program now also provides the Girard_Bruce Volume Tables for 32 ft logs.

11. Stock Table

  • A stock table format has been added to show the various quantities at different log lengths and DBH. The new report is available under the reports option as: “Report #21 Tract: #Trees, Quantity 1 stock Table by DBH, Products and #Logs" as shown:

12. Security and Fool-proofing

  • A "Privilege" setting is provided for you to specify a password for protecting the cruise setup so that other users may not change it. The cruise leader may set up the cruising system then lock the settings of the tree measurement fields to prevent the essential setup from being changed on the PC and on the PDA. A password would be required to make changes to the system.

13. Combining Cruise Data

  • The "SaveAs" function allows the user to change the target folder for saving the job in CE Cruise.

    At the end of a cruise involving multiple cruisers, various cruisers may put their SD cards into the cruise leader's PDA in order to copy their jobs to the leader's PDA. The leader can then come back to the office and use PC-Cruise to combine the jobs.

14. Virtual Tree (a what-if tool)

  • This tool is a volume calculator with a graphic display to help the user quickly see the volume of a log segment by specifying the starting and ending height values for a stem. Options are also available to specify the d.i.b. (diameter inside bark) or d.o.b. (diameter outside bark). To call up the virtual tree dialog, select the Cruise pull-down menu and then select “Virtual Tree”. The following dialog is displayed:

  • First, select the species and product for the tree. Then, specify the DBH, FC and Total Height. Enter the lower height and upper height to define the section of interest on the tree. Based on this information, the program displays a simple sketch of the stem profile and shows the location of the DBH using a dashed line.

    The program displays the bottom end of the log segment as a red line across the stem profile to indicate the location. The top end of the log segment is shown as a blue line. The volume of this log segment is then calculated and automatically displayed for your reference.

    A "Record" button is provided to temporarily record your results. Click on this button to append the volume to a temporary text file. Please note, this file is erased when you exit and restart the PC-Cruise software.

    Use the “View Records” button to call up and display the temporary text file containing the tree measurements and volumes you recorded during your virtual tree session.

15. Move Plot/Point from one timber stand to another

  • A "Move" button has been added to the "Plot/Point Information" screen:

    Click this button to pop-up a window, which allows you to move the active plot to a different stand. Specify the destination position by selecting the target stand from the pull-down menu.
  • Four options are supported for target plot index:
    Nth: Move to input sequence index.
    Start: Move to start
    End: Move to end
    Plot Index: Specify plot index directly.
  • When selecting one of the first three options, the corresponding plot index will be displayed for reference and cannot be changed.

    If you specify a target plot number that is a duplicate with one of the existent plots, then all of the following plots will be renumbered automatically.

    If the plot/point data is tied to a specific grid point location, it is your responsibility to move the stand boundary on the map so that PC-Cruise can match that grid point with the other stand in the map.

16. Automatic shutoff when ready to move to a new Plot

  • You now have the option to have the PDA automatically turn off when you are done with the current plot and are adding a new plot. When you get to the next plot, turn on the PDA and continue to work with the new plot record. Although it is easy to turn off the PDA by pressing the on/off button, you may forget to do so and run out of power too soon.
