Seeing the good from the trees: remotely sensing the urban forest

城市森林提供一系列生态系统服务，包括温度调节和降雨捕获，但目前测量这些效益的成本过高且不准确。本项目旨在开发一种利用遥感三维数据绘制冠层覆盖的城市森林生态系统服务新模型。越来越多的政府正在收集使用这些数据的模型，这代表了既定方法的一种新进展，这种方法需要昂贵和耗时的实地调查。该项目有望取得的进展将意味着环境规划者将能够更好地规划城市森林，使城市在面对气候变化时更宜居、更有弹性。

Urban forests provide a range of ecosystem services including temperature regulation and rainfall capture, but measuring these benefits is currently prohibitively costly and inaccurate. This project aims to develop a new model of urban forest ecosystem services that uses remotely sensed three dimensional data to map canopy cover. A model using this data, which is being collected by an increasing number of governments, represents a novel advance on the established methodology that requires expensive and time-consuming fieldwork. The advancements expected to be made in this project will mean that environmental planners will be able to better plan the urban forest so that cities are more liveable and resilient in the face of climate change.
