The latest generation of 3D Urban Information Models (UIM), created from accurate urban-scale geospatial information, can be used to create smart web services based on geometric, semantic, morphological and structural information at urban scale level, which can be used by local governments to:- improve decision-making on issues related to urban planning, city management, environmental protection and energy consumption based on urban pattern and its morphology;- promote inclusion among various users groups (e.g. elder or diversely able citizens) through services which account for barriers at city level;- involve citizens at wider scale by collecting geo-referenced information based on location based services at urban scale.Based on interoperable 3D UIMs, i-SCOPE delivers an open platform on top of which it develops, within different domains, three 'smart city' services. These will be piloted and validated, within a number of EU cities which will be actively engaged throughout the project lifecycle. The services will address:1) Improved inclusion and personal mobility of aging and diversely able citizens through an accurate city-level differently-abled-friendly personal routing service which accounts for detailed urban layout, features and barriers.2) Optimization of energy consumption through a service for accurate assessment of solar energy potential and energy loss at building level.3) Environmental monitoring through a real-time environmental noise mapping service leveraging citizen's involvement will who act as distributed sensors city-wide measuring noise levels through their mobile phones.All smart services will be based on already available technologies which will be integrated, deployed and made publicly available from a "3D smart EU cities" portal. Potential trust, privacy and data security risks and vulnerabilities, i.e. due to localisation of people, are integral part of the project and will be explicitly addressed.
