Abstract
Urbanisation and Urban sprawl has led to environmental problems and large losses of arable land in India. In this study, we characterize pattern of urban growth and model urban sprawl by means of a combination of remote sensing, geographical information system, Cellular Automata (CA) and agent based modelling. This analysis uses time-series data to explore and derive the potential political-socio-economic- land based driving forces behind urbanisation and urban sprawl, and spatial models in different scenarios to explore the spatio-temporal interactions and development. Agents were integrated successfully into modelling aspects to understand and foresee the landscape pattern change in urban morphology. The results reveal built-up paved surfaces have expanded towards the outskirts and have expanded into the buffer regions around the city. Population growth, economic, industrial developments in the city core and transportation development are still the main causes of urban sprawl in the region. Agent Based modelling approach as seen in this paper clearly shown its effectiveness in capturing the micro dynamics and influence in its neighborhood mapping. Study concludes that integration of remote sensing, GIS, and agent based modelling offers an excellent opportunity to explore the spatio-temporal variation and visualisation of sprawling metropolitan region. This study gives an overview of urbanisation and impacts due to urban sprawl in the region and help planners and city managers in understanding the future pockets and scenarios of urban growth.
