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.
