An enormous amount of spatial data in the Netherlands is nowadays accessible as open data. The use of this data grows exponentially every year. But when users recognised errors in the data, it was a troublesome experience to make the data provider aware about this. Despite even legal obligations for governmental organisations to provide feedback, the amount of feedback was very limited. Until two years ago. In 2016, the Dutch Cadastre (Kadaster), launched the ‘Improve the map’-application (www.verbeterdekaart.nl) to empower topographical data users to provide feedback. This easy-to-use application enabled not only governments, but every user. It is now live for over two years and extended with the Dutch key registry about buildings and addresses. The use of this feedback application has since its launch never dropped and is gaining around 1500 feedback reports every month. More than 90% of the incoming reports are accepted and used to improve the data quality on various quality themes. The application is being further developed to make it easier to use it also for other datasets. This session will show and demonstrate the application, its results and explain its implementation philosophies. It will show that using crowdsourcing for open data can be a major benefit as it provides a continuous quality impulse for our data.
