Urban land-use can be approached from two major points of view. Firstly, it is one of the rudimentary concepts in urban planning which initiates the cornerstone of this discipline and is required to be thoroughly perceived. Secondly, it is one the critical tools to achieve social, economic and physical goals which not only has substantial effects on public and personal investments and decisions, but also plays an undeniable role in improving the quality and rate of physical environment and urban growth respectively. To subscribe to this, outdoor sport and playing space for children can be recognized as the most important urban space for they set up the main elements of community, district and region centers. According to Bertrand Russell “to be able to fill leisure intelligently is the last product of civilization”. Thus, outdoor sport and playing space is one of the key land-uses which should be smartly handled. Tehran with 10 million populations and as the capital city of Iran suffers from insufficient recreational space for children in such a way that any traditional method for locating this space will put obstacles in the way of proper functioning and evidently children will be affected the most. Today, because of complicated urban challenges, particularly in big cities like Tehran, traditional methods for problem solving can no longer satisfy the increasing needs in cities. New methods for locating land-use and services are generally based on geographical information system and computer software's which can store, overlay and analyze great deal of data. Applying these methods is inevitable for smart management of cities. This research tries to investigate the role of GIS in management and planning of cities with emphasize on outdoor sport and playing space planning for children in the city.
