Geographic Automata Systems and the OBEUS Software for Their Implementation

The concept of Geographic Automata System (GAS) formalizes an object-based view of city structure and functioning; OBEUS software implements this view on the operational level. The paper presents the GAS paradigm and latest user-friendly version of OBEUS, the latter based on .NET technology and developed according to OODBMS logic. OBEUS boosts further development of GAS theory, especially regarding the treatment of time in models describing collectives of multiple interacting autonomous urban objects. We claim that all high-resolution urban Cellular Automata and Multi-Agent models of which we are aware can be described in GAS terms and represented as OBEUS applications. GAS and OBEUS can thus serve as a universal, transferable framework for object-based urban simulation.
