Abstract: In this paper we propose a new approach for Big Data mining and analysis. This new approach works well on distributed datasets and deals with data clustering task of the analysis. The approach consists of two main phases: the first phase executes a clustering algorithm on local data, assuming that the datasets was already distributed among the system processing nodes. The second phase deals with the local clusters aggregation to generate global clusters. This approach not only generates local clusters on each processing node in parallel, but also facilitates the formation of global clusters without prior knowledge of the number of the clusters, which many partitioning clustering algorithm require. In this study, this approach was applied on spatial datasets. The pro- posed aggregation phase is very efficient and does not involve the exchange of large amounts of data between the processing nodes. The experimental results show that the approach has super-linear speed-up, scales up very well, and can take advantage of the recent programming models, such as MapReduce model, as its results are not affected by the types of communications.
