Remote Sensing Technology for The Identification and Classifiation or Urban Trees

联合国的预测显示，到2050年，世界上近70%的人口预计将生活在城市地区;超过80%的英国人口已经是城市人口。不断增加的城市人口的健康和福祉是21世纪全球面临的一个关键挑战。城市树木是城市绿色基础设施的重要组成部分，通过其在减轻气候变化影响和减少污染等方面的作用，为城市人口的健康和福祉做出贡献。关于城市树木的种类、大小和健康状况的信息对于地方当局管理其绿色基础设施和相关生态系统服务的提供是必要的。然而，大多数地方当局缺乏这方面的信息，而在实地收集数据并保持最新数据的挑战之大，超出了日益紧张的预算资源的能力。远程收集这些信息的工具将被证明对英国地方政府是非常宝贵的，并有可能在更远的地方应用

UN projections show that by 2050, nearly 70% of the world's population is expected to live in urban areas; over 80% of the UK population is already urban. The health and wellbeing of this increasing urban population is a key global challenge of the 21st century. Urban trees are a critical component of urban green infrastructure that contribute to the health and wellbeing of the urban population through their role in, for example, mitigating climate change impacts and pollution reduction. Information on the species, size and health of urban trees is necessary for local authorities to manage their green infrastructure and associated ecosystem service provision. However, this information is lacking for most local authorities, and the scale of the challenge of collecting the data on the ground, and keeping it current, is beyond the resources of increasingly constrained budgets. Tools for remotely collecting this information will prove invaluable to local governments in the UK, with potential application further afield
