Understanding Spatial Media

USM

A new book from the Kitchin stable. I have a short chapter in it on smart cities and you can get it here. Over the past decade, a new set of interactive, open, participatory and networked spatial media have become widespread.  These include mapping platforms, virtual globes, user-generated spatial databases, geodesign and architectural and planning tools, urban dashboards and citizen reporting geo-systems, augmented reality media, and locative media.  Collectively these produce and mediate spatial big data and are re-shaping spatial knowledge, spatial behaviour, and spatial politics.

My chapter on Producing Smart Cities that you can download here within the book edited by Kitchin, Lauriault and Wilson Understanding Spatial Media brings together a series of ideas from around the globe to examine these new spatial media, their attendant technologies, spatial data, and their social, economic and political effects. The chapters are divided into the following sections: Spatial media technologies. Spatial data and spatial media, and the consequences of spatial media.

City Analytics

OpenSci

City Analytics: An invited special collection of articles for Royal Society Open Science entitled ‘City Analytics’ compiled and edited by Desmond J. Higham, Michael Batty, Luís M. A. Bettencourt, Danica Vukadinovic Greetham and Peter Grindrod. Click here or on the image above for the papers.

The growing human urban population presents unique opportunities and challenges for a range of stakeholders. As is presented in this special collection, using a range of mathematical, computational and statistical tools, it is possible to extract and analyse data on urban environments from myriad sources of information.

In the City Analytics special collection, interdisciplinary work exploring, for instance, social media usage patterns, transport networks and urban resilience to natural disasters, such as flooding, provide researchers and policymakers with detailed insights.

Space Syntax and Spatial Interaction

SSfig

Written a paper on how we can compare and even integrate space syntax with spatial interaction. You can get it here by clicking on this link or on the image above. This is based on the notion that we need to develop a way of disentangling the underlying planar graph of the street network into components that when put together either lead to operations on the planar graph itself as in spatial interaction or on the dual of this graph between the streets which is the graph used in space syntax. The link is obvious when developed in this way but the ways of integration are somewhat convoluted. We develop these ideas for some simple hypothetical graphs and make comparisons of the various accessibilities associated with these graphs which appear both in space syntax and spatial interaction. We then develop a semi-real application using data on the nearest neighbour generic graph for Greater London and this reveals the problems of specifying this graph in the first place. Our comparisons with real data are disappointing for many obvious reasons but what I think this paper does is throw light on space syntax and on ideas about accessibility, suggesting that we need a sustained effort to develop the right sorts of underlying graphs from which space syntax can be developed. We are only at the beginning of the process and in space syntax, we have not really explored the properties of the underlying graphs in any depth hitherto. This establishes directions for further research. Click here for the paper.
