Tree canopies 2008 (Urban Forest)

Tree canopy within City of Melbourne mapped using 2008 aerial photos and LiDAR. The canopy polygons represent actual tree canopy extents on both private and public property across the city. The data is considered accurate for 2008. Changes in tree canopy are expected to have occurred since that time.本数据集为墨尔本市（City of Melbourne）辖区范围内的树冠覆盖数据，基于2008年航空影像与激光雷达（LiDAR）技术绘制完成。数据中的树冠多边形矢量要素，精准表征了全市范围内私有与公共用地上的实际树冠覆盖范围。该数据集的精度以2008年的实际情况为基准，自彼时起，树冠覆盖范围预计已发生变化。
