Work update

Currently at CASA we are exploring ways to simulate various aspects of city life and visualize such models taking advantage of our London database which we are developing along with the advances in graphic card technology and networked communication. We presented some of this work at the AAG last week (click here to download the presentation and here to see the abstract).

Some of this includes modeling traffic. Following on from an earlier post by Andrew-Hudson Smith of Digital Urban about CityScape, the movie below shows our first attempts with the software.

New Developments in GIS for Urban Planning

We just finished writing a brief paper for the April 2009 issue of Geospatial Today entitled "New Developments in GIS for Urban Planning". The paper basically covers new the tools and techniques being developed at CASA which we are targeting at urban planners. Many of the tools are associated with visualising urban problems and their solutions.

AAG Agent Talk

Next week, I will be attending the AAG annual meeting in Las Vegas, which I am quite looking forward to. There seems to be a good selection of agent-based modelling talks along with others relating to GIS, urban planning etc. I will be presenting a paper with Andrew Hudson-Smith in the Modeling Geographic Complexity 2 session entitled "Agents in the City: Modeling and Visualizing Emergent Phenomena."


The abstract for the talk is:

Agent-based modeling (ABM) is increasingly being used as a tool for the spatial simulation of a wide variety of urban phenomena. As ABM moves into the spatial domain, we need new ways to visualize and communicate such models especially to those who we seek to influence and who we believe that such modeling will inform their activities. Coupled with the above challenge is how we represent agents in space. The use of ABM for geospatial simulation has traditionally been dominated by the 2D view of the world with the third dimension rarely ventured into. We would argue that this is due to the nature of the discipline where the focus is on theory rather than outreach and end user visualization; and that model builders are not taking advantage in improvements in computer technology. We will illustrate our attempts to visualize, share and communicate geospatial agent-based models specifically focusing on the third dimension with several examples utilizing 3D Studio Max and Second Life, a virtual online world. These examples range through the movement of cars and pedestrians in a cityscape to evacuation of pedestrians from buildings and residential segregation. These models demonstrate how through the interaction of individual agents complex phenomena emerges over time and in space. Furthermore they demonstrate how different theories and concepts can be incorporated into 3D environments. Additionally these models provide outputs to which non-expert users can easily relate to, thus allowing them to come under greater scrutiny than was possible in the past.

Hope to see you there.

AAG: The Rise of Neogeography

If any readers are attending the AAG next week in Las Vegas, Andrew Hudson-Smith of Digital Urban and myself have organised a session entitled "Concepts, Tools and Applications: The Rise of Neogeography." This session discusses the concepts, tools, applications and challenges arising when collecting, sharing and communicating data for the Neogeographer. The session explores a wide range of topics from Digital Earths, Volunteered Geographic Information and through to Virtual Worlds.

The session will take place on Friday, 27th of March, from 8:00 AM - 9:40 AM in the North Hall N116, Las Vegas Convention Center

The program is as follows:

Hope to see you there!

Challenges and Visions in the Social Sciences

I just come across a very interesting site from the 2008 International Workshop on Challenges and Visions in the Social Sciences organised by Dirk Helbing, Lars-Erik Cederman, Andreas Diekmann, Frank Schweitzer and Didier Sornette. The reason I am blogging about it is that there are over 20 talks available on-line (including slides) identifying future trends in the social sciences, and problems that will have to be addressed. Talks include:

Such a resource should be of interest for anyone interested in computational social science. A short report summarising the workshop can be found here. Which includes: modelling and simulation challenges such as parameter calibration, correlation and causality, Realistic vs. toy models. Along with challenges associated with interdisciplinary research such as the use of terminology, networking and cooperation, information exchange and publication.
