RESUMO

This work presents the mathematical foundations of the Nested Cellular Automata (nested-CA) model, a model of computation for multiple scale Land Use and Land Cover Change studies. The main properties of nested-CA model are described and compared to the agent-based and cellular automata models of computation. The nested- CA model has been implemented in a software environment, called TerraME (Terra Modeling Environment), which provides a high-level modeling language for model description, a set of spatiotemporal data structures for model representation and simulation, a module for spatiotemporal data management and analysis integrated to a geographic information system, and a set of functions for model calibration and validation. We describe the main design choices involved in the development of the TerraME modeling environment. Its architecture is detailed and the main properties are compared with other modeling tools: Swarm, STELLA, and GEONAMICA. Finally, the concept of nested-CA and the TerraME architecture are demonstrated in two applications of land cover change in the Brazilian Amazon.
