Azimuth

This function allows specifying a particular tree as a reference point, designating a direction as the north, constructing a polar coordinate system, and then calculating the azimuth angle and horizontal distance.

Steps

1.Click on Azimuthbutton, pop-up azimuth toolbar, and settings window:

Function description

• Set north: Specify the north direction, providing X, Y, and custom modes. In the custom mode, determine the north direction by drawing two points.
• Set reference tree: Select a single tree seed point as the reference tree.
• Calculate: After completing the orientation and reference tree settings, you can calculate the azimuth angle and horizontal distance for all single tree seed points and fill them in the respective fields.
• Clear: Used to reset the north direction and reference tree, simultaneously clearing the azimuth angle and horizontal distance values for seed points.
• Exit: Exit function

2.First, click on the "Set Reference Point" button. Then, in the azimuth dialog, choose the direction as needed. Next, select a seed point as a reference. In the azimuth dialog, locate the parameter tree's ID. Finally, click on "Calculate."

3.After the calculation is complete, select the tree layer in the directory, right-click to open the dropdown menu, then click on "Attribute Table." In the table, select a seed point. You can find the azimuth and angle from the reference point to the selected seed point, and the result values will be stored in the corresponding fields.
