Abstract:
Smart cities are cities that provide core infrastructure and give a decent quality of life to its citizens. Core infrastructure includes adequate water supply, assured electricity supply, sanitation including solid waste management, health and education etc. Since cities always lack open space, roof area of buildings can be used to provide infrastructure. For example, solar Photovoltaic (PV) Systems can be installed on rooftops of residential, commercial or industrial premises and the electricity generated from such systems could either be entirely fed into the grid or used for self consumption. Given the importance of roof area, this research emphasized on automated extraction of urban roof area in both tropical and nordic urban environment to compare and contrast the set of rules needed for their automated delineation. Bhopal city, India and Trondheim City, Norway are selected as study areas because they represent tropical and nordic urban environment respectively. An existing set of rules for automated extraction of urban roof area of Bhopal city was developed in 2016 using object-oriented classification tools, available through eCognition Developer (V. 8.7.2). A smaller residential neighbourhood in Bhopal city has been selected as Test Site and World View 2 stereo pair & multispectral images were used as input data. After successful extraction of urban roofs of Bhopal city, the method was applied to extract residential roofs of Trondheim city from high resolution orthophotoes. Several adjustments were needed due to the morphologic differences between roofs of two different cities. Visual comparison with manually delineated roof area confirms the success of this revised automated method in two different environments. The quantification of roof area further helped to estimate solar energy potential through rooftop PV of these two cities.
