GAMA (Gis & Agent-based Modelling Architecture) Platform

While I have blogged about creating geographically explicit agent-based models with Repast, MASON, NetLogo and several other toolkits before, I recently came across an open source toolkit called Gis & Agent-based Modelling Architecture or GAMA for short. GAMA is developed by UMMISCO and to quote from the site:
"GAMA is a simulation platform, which aims at providing field experts, modelers, and computer scientists with a complete modeling and simulation development environment for building spatially explicit agent-based simulations." 
The site offers a series of tutorials, supporting documents and publications which show the potential of GAMA. The movie below gives an excellent overview of what GAMA can do. 

Agent-Based & Cellular Automata Models for Geographical Systems @ the AAG

If you attending the AAG Annual Meeting this year, please feel free to come to our sessions entitled Agent-Based and Cellular Automata Models for Geographical Systems.

Saturday, April 13th, from 8:00 AM to 6:00 PM in Angeleno, The LA Hotel, Level 2  

The use of Agent-based Modeling (ABM) and Cellular Automata (CA) models within geographical systems are starting to mature as methodologies to explore a wide range of geographical and more broadly social sciences problems facing society. The aim of these sessions is to bring together researchers utilizing agent-based models, CA (and associated methodologies) to discuss topics relating to: theory, technical issues and applications domains of ABM and CA within geographical systems.

Papers will discuss issues relating to:
  • Validation, verification and calibration of Agent-based and CA models
  • Hybrid modeling approaches (e.g. utilizing Spatial Interaction, Microsimulation, etc.)
  • Handling scale and space issues
  • Visualization of agent-based models (along with their outputs)
  • Ways of representing behavior within models of geographical systems
  • Participatory modeling and simulation
  • Applications: Ranging from the micro to macro scale
