The aim of this study is to evaluating urban expansion through Cellular Automata model on different neighbourhood size in Erbil city, Kurdistan region, IRAQ. The different type of Cellular Automata model is utilized to simulate land use/cover change based on different neighbourhood size to 1985 and to predict the pattern of urban extent in 2050. A FCA interface as first method guided cellular automata approach. The CA-Markov land cover change model was second method that has been successfully applied for simulating Erbil expansion. Based on geographical entity, many restrictions existing in standard CA are released in VecGCA.
