Abstract:

UAV aerial photogrammetry technology was used to investigation the occupation and damage of woodland in a quarry. The field test showed that the UAV photogrammetric efficiency was more than 3 times higher than that of the traditional manual surveying method. The use of oblique photography could accurately reflect the status of the quarry, and the mapping accuracy reached 1: 500 scales.

Key words: UAV aerial photogrammetry； oblique photography technique； GDCORS
