Open data is becoming increasingly important and there are considerable advantages, such as accountability, cost and time savings for users, easier knowledge sharing and increased efficiency in public services.
The importance of open data is more and more recognized (see e.g., this blog article (in Dutch) and this and this report). However, to bank on such advantages, there is a need to increase awareness about open data and make it easy to find and use the open data.
For the Netherlands, a lot of open data is available, but not always easy to find. However, there are a number of sites that will help you to find the data you need. Some I have looked at more recently are:
- The Engage portal provides an overview of European public sector data sets available online. For the Netherlands it lists 19 data sets from national and local government
- One of the websites listed on Engage is the Nationaal Georegister, a data portal / search engine for geo-information of the Netherlands.
- The search engine OpenDataNederland.org provides a searchable catalogue of Dutch open data sets (166 data sets to date).
There are many more sites you may want to check out, but with these three you should be able to find quite a lot of open data available for/from the Netherlands. If you know of other useful search engines / data portals or the like, let me know in the comment section below.
