Beschreibung
Zusammenfassung:	The invention discloses a rapid mountainous individual tree absolute positioning and coordinate correction method applied to quickbird images. The method comprises the steps of 1, combining a handheld GPS (global positioning system) and a total station with a method for acquiring coordinates of individual trees in a sample plot; 2, providing a method for avoiding a wrong measurement result caused by perversion in a process of inputting GPS point coordinates into the total station; 3, respectively performing orthorectification on full-color images and multispectral images of the quickbird images, and then fusing the full-color images and the multispectral images to guarantee positioning precision, so that further extraction of individual tree information can be facilitated.
