GAMA (GIS & Agent-based Modelling Architecture)


The “GIS and Agent-Based Modeling” blog reports on GAMA, an open source GIS-ABM tool that looks quite interesting:

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. It is being developed by several French and Vietnamese research teams under the umbrella of the IRD/UPMC International Research Unit UMMISCO since 2007.

GAMA provides the modeler with:

– The ability to use arbitrarily complex GIS data as environments for the agents.

– The possibility to run simulations composed of vast numbers of agents (up to millions).

– A way to conduct automated controlled experiments on various scenarios, with a systematic, guided or “intelligent” exploration of the space of parameters of models.

– The possibility to let users interact with the agents in the course of the simulations.

A demo video is also available.

On the Esri side, check out the (free) Agent Analyst extension.

PS: I have my own consultancy and love to work on interesting problems. I have helped several startups and established companies deploy innovative GIS and Data Engineering solutions. Check out some showcases of my work at If you have a project that we can collaborate on, then please contact me at
