Rise of the Colourful Circles – Election 2010 Visualisation
I’ve fixed and tidied up a visualisation I created back in 2010, which showed the results of that year’s General Election in the UK. Newer versions of OpenLayers had broken it (specifically the use of addUniqueValueRule with a custom context resulted in no circles appearing) and also the UI looked rather rudimentary. Now it has […]

Developing classical and contemporary models in ESRI’s City Engine- CASA Working Paper 191
ESRI’s City Engine not only is a great urban generator, but it also provides the ideal approach for turning the 3D virtual city into an urban modelling tool. Procedural modelling visualizes the results of mathematical models on a 3D Environment and simulate the changes real-time, providing all the necessary features for testing the consequences of Urban modelling theories onto the physical form of the urban environment.
I am very excited to have this first paper published in the CASA UCL webpage.
Abstract:
In this paper we describe the development of projects which aim to explore the use of procedural modelling as a complete toolkit for building interactive visualizations of urban modelling theories. We will use three case studies, starting with the original von-Thunen model, a generalization of von-Thunen using multiple centres and finally the standard dynamic retail model by Wilson and Harris. We will discuss the advantages and limitations in using ESRI’s City Engine and the use of interactive techniques, to visualize and explore classical and contemporary urban modelling theories, by introducing spatial interaction and spatial dynamics within the simulation of a 3d city. In this framework, we provide a guide for developing urban models to aid better analysis and understanding of the urban environment through 3d urban visualizations, complexity theories and interactive systems.

Limitless London
Defining urban boundaries is certainly an undefined topic. A proof is the recent “boarderless” competition where the winning projects swing between creating a functional built form of the boundary, or revolved around the notions of non-permanence and instability. The winning project ‘Floating Border Project’ by Hélène Grialouand Sebastien Gafari, creates a moving boarder. “The shaded frontier is moving throughout hours, days and seasons. The installation is composed of an inflatable structure which consists of a balloon cloud upon the Temple. These balloons calculate the weather forecast, wind and luminosity. During bad weather, the limit on the ground disappears and the aerial structure lights up to become a signal seen by the both two countries.”
As urban planning and architecture integrates advanced techniques from computer science, big data and other sciences, it is affecting the built environment in both design and construction. New techniques which introduce complex calculations of different data feeds have led professionals of the build environment to slightly change their role and find solutions in relation to design and function with a clear focus on optimization and efficiency.
In the movie “Limitless” – 2011, a writer finds the “golden” pill, which allows him to access all of his potentials, giving him fulfilment in life- work and relationships and to accomplish his every goal. The intro of the film, is a very good metaphore of the limitless city. A reflection of todays fluxuating society and the rush to adjust to something that looks as if “it” has begun and as if “it” has no ending.

In another film by K. Giannaris, “From the Edge of the City” , the undefined city boundaries represent a more vague image of the people who live in the edge of social acceptable. In today’s society, to be able to learn quick and easy so as to be as efficient as possible is part of this new world and this tends to be a dominant idea of the new urban utopia. Are we giving our cities some technological shots in the end? Are the boarders going to be defined by what is unable to adjust; inhabited by the marginalized of those without smart-phones?
And so, inspired by the brilliant intro of “Limitless” – here is a google maps version for the city of London. Of course not as well executed, but an animation using Google maps and some free sounds from http://soundbible.com, turned out to be something very quick and easy to do.

Throwing the spatial analysis ‘baby’ out with the big data ‘bathwater’
Three days at the splendidly organised Twelfth International Conference on GeoComputation (Wuhan, China, 23rd-25th May) have provided a welcome opportunity for intellectual refreshment in the company of old friends and colleagues. Nevertheless an irritating feature of the meeting has been the apparently endless queue of speakers with diverse national and intellectual backgrounds all wanting to …
