%X The data set mainly includes the observation data of each tree in the super sample plot from June 2, 2008 to June 10, 2008 The super sample plot is set around dayaokou guantan forest station. Because the size of super plot is 100m × 100m. In order to facilitate the tree survey, it is divided into 16 sub sample plots. The tree survey of each tree is carried out in sub sample plots. The measurement factors of each tree include: DBH, tree height, height under branches, crown width in cross slope direction, crown width along slope direction and single tree growth. The main measuring instruments are: tape measure, DBH ruler, laser altimeter, ultrasonic altimeter, flower pole and compass. The data set also records the longitude and latitude coordinates of the center point of 16 sub plots (measured by z-max DGPS) The data set can be used to verify the extraction algorithm of forest structural parameters from remote sensing. Together with other observation data of super sample plot, this data set can be used for forest 3D scene reconstruction, active and passive remote sensing mechanism model establishment, remote sensing image simulation and so on
