Recently, cities are facing many challenges which negatively affect their urban fabric as well as the services provided to the population. Collecting data obstacles from public space in unplanned areas is more intricate than elsewhere. In light of absence of follow-up of informal areas distinctive features, collecting data has become a hard process. This leads to the failure of many repeated attempts to upgrade unplanned areas. Lately, information and communication technology (ICT) has provided many tools to handle city problems. However, these tools are dispersed and lack integration with action plans. This research aims to spotlight on the importance of collecting planning data related to public space in unplanned areas using information and communication technology. This can be achieved through integrated methodology in which the theoretical study of previous researches and analysis of previous experiences are combined together. Finally, this research pinpoints the challenges of data collection from public space in unplanned areas; such as variable dynamics, speed of changes and diversity of patterns of encroachment. The study concludes that smart city is not a goal, but rather a means to achieve a target. This target aims at permitting the city and public space to fulfil the purpose for which it was established; meeting the needs of the population and bridging the gap between demand and resources or services. In addition, achieving a quality of life for the residents to help public spaces to act as the nodes forming the smart city.
