“…Green roofs offer many other public and private benefits. Public benefits include the promotion of biodiversity, reduction of stormwater runoff, lessening of air pollution and improved urban comfort [10][11][12][13][14]. Private benefits include energy savings by decreasing indoor cooling load demand, noise attenuation, longevity of the waterproof membrane and green space available for recreation [4,[15][16][17].…”

Information about green spaces available in a city is essential for urban planning. Urban green areas are generally assessed through environmental indicators that reflect the city's quality of life and urban comfort. A methodology based on 3D measure and analysis of green urban areas at the city scale is presented. Two products are proposed: (1) measuring current vegetation cover at ground level through object-oriented classification of WorldView-2 imagery; and (2) estimating potential green cover at rooftop level using 3D data obtained by LiDAR sensor. The methodology, implemented in Lisbon, Portugal, demonstrates that: (1) remote sensing imagery provides powerful tools for master planning and policy analysis regarding green urban area expansion; and (2) measures of urban sustainability cannot be solely based on indicators obtained from 2D geographical information. In fact, 2D urban indicators should be complemented by 3D modelling of geographic data.
