Urban forests play a critical role in mitigating heat island effects and in modifying local microclimates by intercepting solar radiation and shading heat-absorbing structural materials. Solar radiation is the prime determinant of how much energy urban surfaces absorb and of temperature distribution patterns in urban areas. Understanding the impacts of urban trees on solar radiation received by buildings is an important way to assess tree shading and potential energy conservation. In this study two remote sensing technologies have been integrated, to estimate solar radiation on building roofs along two major infrastructure routes in Sydney. In particular, the relationship between the radiation received by the roofs and the surrounding tree features has been investigated. The two chosen sources of remotely sensed data are light detection and ranging (LiDAR), and airborne hyperspectral imaging. Integrating these data …
