The management of urban trees, particularly those planted along roadways or utility corridors, intersects with transportation policy and public safety, as unhealthy and decaying trees are potentially hazardous to pedestrians, motorists, buildings and electrical lines. City utilities must implement intensive vegetation maintenance and management plans, whose effectiveness, in turn, must be informed by comprehensive information on tree and vegetation location, health and vitality. Despite the considerable financial investment represented by urban trees and removal of invasive species access to this type of information is rare. In this proposal, we undertake a research program that explores LiDAR and hyperspectral imagery potential for assessing vegetation condition. Building on previous research funded through the NSERC Engage and Engage + grants in collaboration with Surrey City Energy, we will apply automated algorithms to locate, outline and measure urban trees in the city of Surrey, British Columbia. We will also detect and map the distribution of invasive plant species in Surrey. By applying this approach to vegetation across the city, spatial patterns in tree condition and invasive species will then be mapped and examined.

城市树木的管理，特别是那些种植在沿着道路或公用设施走廊的树木，与交通政策和公共安全交叉，因为不健康和腐烂的树木对行人、驾车者、建筑物和电线有潜在的危险。城市公用事业必须实施密集的植被维护和管理计划，其有效性反过来又必须通过有关树木和植被位置、健康和活力的全面信息来了解。尽管在城市植树和清除入侵物种方面投入了大量资金，但获得这类信息的机会很少。在这项提案中，我们开展了一项研究计划，探索LiDAR和高光谱图像评估植被状况的潜力。在以前的研究资助通过NSERC参与和参与+赠款与萨里城市能源合作的基础上，我们将应用自动算法来定位，概述和测量城市树木在萨里，不列颠哥伦比亚省。我们还将检测和绘制入侵植物物种在萨里的分布。通过将这种方法应用于整个城市的植被，树木状况和入侵物种的空间格局将被绘制和检查。
