This work presents a novel geospatial mapping service, based on OpenStreetMap, which has been designed and developed in order to provide personalized path to users with special needs. This system gathers data related to barriers and facilities of the urban environment via crowdsourcing and sensing done by users. It also considers open data provided by bus operating companies to identify the actual accessibility feature and the real time of arrival at the stops of the buses. The resulting service supports citizens with reduced mobility (users with disabilities and/or elderly people) suggesting urban paths accessible to them and providing information related to travelling time, which are tailored to their abilities to move and to the bus arrival time. The manuscript demonstrates the effectiveness of the approach by means of a case study focusing on the differences between the solutions provided by our system and the ones computed by main stream geospatial mapping services.

In the entertainment industry, technology advances are continuously improving and evolving the portfolio of services and distinguished features that can be experienced by the audience, whether it is attending the event on site or remotely. In this context, the SkyMedia system aims at exploring, designing, and demonstrating a novel multimedia end-to-end architecture that can provide unique immersive media experiences to audience during live events. UAV and WSN technologies play a central role as enabling technologies. UAVs capture HD and 3D videos and images from the sky, while wireless sensors form an augmentation network acquiring side-information to be fused with the main audiovisual contents. All technologies come together to form a very advanced Multimedia Service Platform able to manage in real-time HD/3D processing, and an immersive media experience demonstration is going to be performed during a public live event in order to prove the effectiveness of the system. Index Terms-3D processing, UAV-based capturing, wireless sensor networks, multimedia delivery, immersive and interactive services, live events.
