Cities play a key role in sustainable development. Urban growth must be managed in ways that support and drive economic development, and achieve social cohesion and environmental sustainability. The concept of Smart Cities emerged in the same way as Smartphones or Smart TVs. A number of initiatives are being developed as part of Smart City projects; however, there is a lack of consistent indicators, databases and methodologies for assessing, financing, and implementing these kinds of initiatives. Smart City projects today are classified according to six clusters known as axes: Mobility, Environment, Government, Economy, People and Living. The main aim of this paper is to show dynamically and graphically the scope of development of Spanish Smart City initiatives in terms of mobility and environmental issues, as two of the fundamental axes of Smart City development. The study was carried out in the 62 cities in the Spanish Smart Cities Network (RECI). The interactive map describes the status of Spanish cities by means of socioeconomic and demographic indicators and provides a thorough assessment of the maturity of Smart Cities based on their variables.
