GIS has emerged from the scientific laboratories, conventional cartographer table into the heart of urban and regional planners, policy makers. This paper examines how GIS can improve collaboration in decision making among the three basic components of proposed ‘3-piller smart city model’ and needed in order to create an innovative, prosperous, civic and sustainable Smart Cities. GIS technology is currently converging with several other technologies to provide new levels of accessibility and functionality. Along with GIS the use and integration of these various technologies to simulate and interpret the sustainability problems leads to a deeper understanding on sustainable smart development especially in economics, society, environment and housing. The current study presents two smart city projects that justify the potential of sustainable development in India. This development enables new principles that are proven sustainable for self contained world. And ultimately the paper helps to understand the use of GIS and its integration with various approaches to formulate, simulate, interpret and validate the sustainable development of urban areas, steering a smart and sustainable future for smart cities
