Abstract

The opera industry wants to renew its audience and has undertaken several strategies based on digitalization and audiovisual broadcasting to achieve it. In order to attract and create a stronger bond with new audiences, it is exploring different ways to update its information policy and modernize its image. By means of Internet, it has managed to get the opera show offstage, bringing it closer to the daily lives of its spectators thanks to video on demand (VOD) and to live streaming broadcastings. It has made the most of mobile devices to enhance their shareable presence, imitating the audiovisual commercial trends to arouse enthusiasm among its viewers and creating social networks to offer the audience a referential background. Finally, the opera industry looks upon its current state and its social integration as a means of regaining its relevance.

Abstract

The updating of changing information plays a significant role in ensuring the quality of OpenStreetMap, which is usually completed by mapping the whole changing objects with a high degree of uncertainty. The incremental object-based approach provides opportunities to reduce the unreliability of data, while challenges of data inaccuracy and redundancy remain. This paper provides an incremental outline-based approach for OpenStreetMap data updating to solve this issue. First, incremental outlines are delineated from the changed objects and distinguished through a spatial classification. Then, attribute information corresponding to incremental outlines is proposed to assist in describing the physical changes. Finally, through a geometric calculation based on both the spatial and attribute information, updating operations are constructed with a variety of rules to activate the data updating process. The proposed approach was verified by updating an area in the OpenStreetMap datasets. The result shows that the incremental outline-based updating approach can reduce both the time and storage costs compared to incremental objects and further improve data quality in the updating process.
