Big Data appears in many forms. They may contain valuable information that could be used for a whole range of applications. At the official statistical office of the Netherlands, Statistics Netherlands, a considerable amount of effort is put into getting access to Big Data sources and extracting information from them to study their potential use. Ultimate goal of the office is to use Big Data for the production of reliable and rapidly available statistics. In the presentation examples of the work are shown, for both successful and unsuccessful approaches, and the problems ran into are discussed. Big Data sources studied are Mobile phone network data, Web pages of companies, Social media, Radio signals of ships, Road sensor data and Satellite/Aerial pictures. The results shown were obtained at the Center for Big Data Statistics of Statistics Netherlands and during the European project on Big Data lead by Statistics Netherlands.
