Top  Previous  Next

The Tree surveying extension is not part of the core DigiTerra Explorer. It is an additional software module for surveying trees with GPS/GNSS receiver and Lasertech Trupulse 360B. It can be accessed in the menu bar: Tools > dtToolTreeSurveying Tree surveying and in the toolbar with the dtToolTreeSurveying Tree surveying button.

 Reference Point #0  - Tap on this button to define your standing point on the field with the Add new reference point panel. "#0" means that your standing point is not yet defined.

 

 Reference Point #1  - "#1" means that you are on the first standing point. Tap on this button again if you want to measure more trees from an other standing point.

 GPS  - takes over the Easting, Northing coordinates of the current GPS position to define the standing point at the current GPS location.

 

 Ok  - saves the standing point and then closes the panel

 

 Cancel  - closes the panel without saving the standing point

Polar position: Displays the measured values. You can also enter the values in [degree, meter].

 

 Measure  - Displays the following message box: "DigiTerra Explorer controls TruPulse 360B to measure an Azimuth (AZ) and Horizontal Distance (HD). Look through the eyepiece and use the crosshair to aim to the target. Press-and-hold the FIRE button." The message box closes automatically once your finished the measurement.

 

Tree height: Displays the measured value. You can also enter the values in [meter].

 

 Measure  - Displays the following message box: "DigiTerra Explorer controls TruPulse 360B to measure the Tree height with the Height Routine. Height Measurements involve a simple routine that prompts you to take 3 shots to the target: HD, INC base (or top), and INC top (or base). The TruPulse uses these results to calculate the height of the target." The message box closes automatically once your finished the measurement.

 

Trunk height: Displays the measured value. You can also enter the values in [meter].

 

 Measure  - Displays the following message box: "DigiTerra Explorer controls TruPulse 360B to measure the Trunk height with the Height Routine. Height Measurements involve a simple routine that prompts you to take 3 shots to the target: HD, INC base (or top), and INC top (or base). The TruPulse uses these results to calculate the height of the target.

" The message box closes automatically once your finished the measurement.

 

Stem diameter: Displays the measured value. You can also enter the values in [meter].

 

 Measure  - Displays the following message box: "DigiTerra Explorer controls TruPulse 360B to measure the Stem diameter with the Missing Line Routine. The Missing Line Routine calculates distances and angles to describe the relationship between two extremities of the stem. The simple routine prompts you to take two shots to targets: "Shot 1” and “Shot 2”." The message box closes automatically once your finished the measurement.

 

Crown diameter: Displays the measured value. You can also enter the values in [meter].

 

 Measure  - Displays the following message box: "DigiTerra Explorer controls TruPulse 360B to measure the Crown diameter with the Missing Line Routine. The Missing Line Routine calculates distances and angles to describe the relationship between two extremities of the crown. The simple routine prompts you to take two shots to targets: "Shot 1” and “Shot 2”." The message box closes automatically once your finished the measurement.

k-tip-iconThe measurement can be repeatable by tapping on the Measure button.

 New (Num#0, Total#0)  - Displays the currently measured Tree's number and the total number of surveyed trees. Tap on this button to start surveying a new tree.

 

 Undo  - Removes the last measurement.
