CHM Segmentation Result

The CHM segmentation result contains a comma-separated .csv table file and a polygon-type .shp vector file.

The .csv table contains the attributes of tree ID, x, y coordinate position, tree height, crown diameter and crown area.

The following table shows an example of the segmentation result of CHM:

TreeID, TreeLocationX, TreeLocationY, TreeHeight, CrownDiameter, CrownDiameter(S-N),CrownDiameter(E-W),CrownArea
1, 322716.24, 4102494.69, 36.165, 8.982, 9.865, 8.099, 63.36
2, 322751.21, 4102499.9, 41.282, 4.491, 5.132, 3.850, 15.84
