Mapping Twitter activity and City Twitter Mapping is an increasingly useful method to link virtual activities and geographical space. It shows the dynamics of activities in urban space, such as political events. Geo-tagged tweets that illustrate Twitter users’ location are an effective resource to analyse the linkage between protests and communications. This presentation focuses on the spatial relationship between the density of geo-tagged tweets and a large anti-government protest in London on 20 June 2015. The tweets are aggregated to hexagonal grid cells to visualise activity density in different Central London areas. Mapping and visualisation in three dimensions( 3D) identify the spatial densities and patterns of the tweets, and provide a comprehensive analysis of the geography of activities during the protest march.
Songdo: the hype and decline of world’ s first smart city New Songdo City in South Korea has been under construction since 2004 with the objective of becoming the first ubiquitous city or smart city in the world. However, as the aims of New Songdo City have been altered as the project has evolved step by step, the city of $ 35 billion investment has faced severe criticism that it is not the blueprint for the future cities that was expected. This presentation looks at the brief history of New Songdo City in the context of the policy background to make a better environment based on Information and Communication Technologies( ICTs) and examines why it is not an ideal urban model through the smart city perspective.
