Overheating London and the Evolving North: Visualising Urban Growth with LuminoCity3D.org

Urban policy is currently riding high on the UK political agenda. A combination of the desire to rebalance the UK economy away from financial services; debates over massive high-speed rail investment; the worsening housing crisis in the South-East; and city devolution demands following the Scottish referendum, all point to major reform. As we move towards the 2015 general…

Geosimulation and Big Data: A Marriage made in Heaven or Hell?

http://www.pinterest.com/pin/101753272804937744/
Call for papers: AAG 2015 – Geosimulation and Big Data: A Marriage made in Heaven or Hell?

In recent years, human emotions, intentions, moods and behaviors have been digitized to an extent previously unimagined in the social sciences. This has been in the main due to the rise of a vast array of new data, termed ‘Big Data’. These new forms of data have the potential to reshape the future directions of social science research, in particular the methods that scientists use to model and simulate spatially explicit social systems. Given the novelty of this potential “revolution” and the surprising lack of reliable behavioural insight to arise from Big Data research, it is an opportune time to assess the progress that has been made and consider the future directions of socio-spatial modelling in a world that is becoming increasingly well described by Big Data sources.

We invite methodological, theoretical and empirical papers that that engage with any aspect of geospatial modelling and the use of Big Data. We are particularly interested in the ways that insight into individual or group behavior can be elucidated from new data sources – including social media contributions, volunteered geographical information, mobile telephone transactions, individually-sensed data, crowd-sourced information, etc. – and used to improve models or simulations. Topics include, but are not limited to:
  • Using Big Data to inform individual–based models of geographical systems;
  • Translating Big Data into agent rules;
  • Elucidating behavioral information from diverse data;
  • Improving simulated agent behavior;
  • Validating agent-based models (ABM) with Big Data;
  • Ethics of data collected en masse and their use in simulation.
Please e-mail the abstract and key words with your expression of intent to Nick Malleson by 28th October, 2014. Please make sure that your abstract conforms to the AAG guidelines in relation to title, word limit and key words and as specified at http://www.aag.org/cs/annualmeeting/call_for_papers.

A great urbanist_Peter Hall




The book cover of ‘Cities of Tomorrow: An Intellectual History of Urban Planning and Design in the Twentieth Century’


Yesterday I was surprised when I searched some new journal articles through UCL library’s E-Journal service. Volume85, Number 5, 2014 of Town Planning Review that was published just some days ago includes a new paper of Professor Peter Hall. Unfortunately, it is still unable to look through the UCL service, ‘And one fine morning -’: reflections on a double centenary, the paper can arouse the glad to read his words as well as the grief losing a great urbanist who passed away on 30 July 2014. 

 



I, had trained as an architectural designer, started to have an interest in urban studies after reading one of his tremendous books ‘Cities of Tomorrow: An Intellectual History of Urban Planning and Design in the Twentieth Century.’ The book carefully and attractively introduced the history of modern cities from the 19th century to the end of the 20th century and it unveiled hidden stories that had built on the characteristics of each city step by step. The most interesting point what I found in this book, his vision for the city is not heading for built forms, but alternative society as Ebenezer Howard pursued. And it was entirely enough to bring the young student to London.

 



After I have entered The Bartlett, UCL, I had the opportunity to audit his seminar class for masters’ students. Every week, students groups analysed urban problems of particular cities in the world and studied how urban policies have intervened in the problems. When I listened his comments in the class, I could imagine Kung-Fu masters who simply overwhelmed many fighters in the movie what I watched long years ago . He looked like he knew everything about cities, and he was thoroughly conversant with geographical, economic and social issues from European cities to Sydney, Singapore and Global South. 

Recently, Regional Studies that Peter Hall worked as the first editor published a virtual special issue to commemorate him. In the editorial page, Nicholas A. Phelps and Mark Tewdwr-Jones admire him highly as the academic who “successfully brought together in his career – history, geography and planning” and explained his achievements based on his articles in the issue that you can freely access. 

I have made the list of his recent books.

The Planning Imagination: Peter Hall and the Study of Urban and Regional Planning  

Good Cities,Better Lives: How Europe Discovered the Lost Art of Urbanism

 

Also I have checked his lecture videos on online.
Youtube and Vimeo contain some his lectures, but the following videos might be useful to watch.

I recommend seeing Michal Batty’s tribute for Peter Hall.

Hope this post could be helpful to remember Professor Peter Hall and his works

ModelTube

  ModelTube is the name of the project to integrate agent based modelling into MapTube. Back at the end of last year I did a blog post on how to integrate AgentScript with Google Maps: http://www.geotalisman.org/2013/12/18/bugs-on-a-map/. Following on from this, I used the AgentScript agent based modelling framework, which is based on NetLogo, to visualise the tube …

International Encyclopedia of Geography – Quality Assurance of VGI

The Association of American Geographers is coordinating an effort to create an International Encyclopedia of Geography. Plans started in 2010, with an aim to see the 15 volumes project published in 2015 or 2016. Interestingly, this shows that publishers and scholars are still seeing the value in creating subject-specific encyclopedias. On the other hand, the weird […]

New Paper: ABM Applied to the Spread of Cholera

Cholera transmission through the interaction
of host and the environment
We are pleased to announce we have just had a paper published in Environmental Modelling and Software entitled “An Agent-based Modeling Approach Applied to the Spread of Cholera
Research highlights include:
  • An agent-based model was developed to explore the spread of cholera.
  • The progress of cholera transmission is represented through a Susceptible-Exposed-Infected-Recovered (SEIR) model. 
  • The model integrates geographical data with agents’ daily activities within a refugee camp.
  • Results show cholera infections are impacted by agents’ movement and source of contamination. 
  • The model has the potential for aiding humanitarian response with respect to disease outbreaks.
Cholera dynamics when rainfall is introduced.

Spatial spread of cholera over the course of a year.
Study area
If the research highlights have not turned you off, the abstract to the paper is below:
“Cholera is an intestinal disease and is characterized by diarrhea and severe dehydration. While cholera has mainly been eliminated in regions that can provide clean water, adequate hygiene and proper sanitation; it remains a constant threat in many parts of Africa and Asia. Within this paper, we develop an agent-based model that explores the spread of cholera in the Dadaab refugee camp in Kenya. Poor sanitation and housing conditions contribute to frequent incidents of cholera outbreaks within this camp. We model the spread of cholera by explicitly representing the interaction between humans and their environment, and the spread of the epidemic using a Susceptible-Exposed-Infected-Recovered model. Results from the model show that the spread of cholera grows radially from contaminated water sources and seasonal rains can cause the emergence of cholera outbreaks. This modeling effort highlights the potential of agent-based modeling to explore the spread of cholera in a humanitarian context.”
Finally to aide replication, experimentation or just explore how you can link raster and vector data in GeoMason, we have a dedicated website where you can download executables of the model along with the source code and associated data. Moreover we have provide a really detailed Overview, Design concepts, and Details (ODD) Protocol document of the model.
