Spatial data generated by an Internet of Things (IoT) network is important to assist the decision-making in issues related to smart cities. In these cities, IoT devices generate spatial data constantly. Thus, data get increasingly voluminous very fast. In this paper, we investigate the challenge of managing these data through the use of a spatial data warehouse and spatial on-line analytical processing designed over a parallel and distributed processing framework extended with a spatial analytics system. We propose a novel architecture aimed to assist a smart city manager in decision-making, which integrates a cloud layer where these technologies are located with a fog computing layer for extracting, transforming and loading. Furthermore, we introduce a set of guidelines to aid smart cities managers to implement the proposed architecture. We validate our architecture with a case study that uses real data collected by IoT devices in a smart city.
