多源空间数据在古树数字化保护中的应用OA

This article proposed a digital protection method based on multi-source spatial data to address the issue of construction affecting the healthy growth of ancient trees.Firstly,unmanned aerial vehicle oblique photogrammetry technology was used to obtain comprehensive image data of ancient trees and their surroundings,and the image data was constructed into orthoimages and realistic three-dimensional models.Based on this data,a large-scale topographic map of the ancient tree surroundings was drawn with targeted measures.Three-dimensional laser scanning technology was used to conduct multi-station and all-around scanning and stitching of ancient trees and construct a three-dimensional spatial model from their point cloud data.Then,by combining the result data of both,a professional analysis of the ancient tree and its surrounding environment was conducted,and a plan that is helpful for the healthy growth of the ancient tree was proposed and implemented.Finally,the management of ancient trees was visualized and digitized.The results show that the method produces fine and efficient data and has a significant effect on the digital protection of ancient trees.This provides reference and guidance for the future digital protection of ancient trees.
