A selection of data portals will help you on your way.
Before you start the extensive data collection process, it is advisable to find out which geo-data is already available. Government and semi-government institutions have very diverse datasets, which are largely made available according to general standards. The websites below offer a selection of good and reliable data that in most cases is made available for free.
PDOK - Public Services on the Map
Public Services on the Map (PDOK) is a platform for unlocking geodata sets of Dutch governments. This is current and reliable data for both the public and private sectors. PDOK makes digital geo-information such as data services and files available. The PDOK services are based on open data and are therefore freely available to everyone.
PDOK was established through a collaboration between the Land Registry, the Ministries of Infrastructure and Water Management, the Interior and Kingdom Relations and Economic Affairs and Climate, Rijkswaterstaat and Geonovum. PDOK is an open initiative. Any government organization that wants to make its geodata available for reuse can turn to PDOK.

NGR - National Georegister
The National Georegister is the source of geo-information in the Netherlands. The simple search options and presentation of results allow the datasets to be viewed or downloaded in the map viewer.

Data.overheid.nl is the National Data Portal of the Dutch government. On this portal you will find data made available by the Dutch government.
Facts and numbers
- More than 180 government organizations have published data on data.overheid.nl.
- Almost all datasets are updated every night.
- The DCAT standard is used as a metadata standard to exchange data with each other.
- Datasets are published via CKAN.

Open Mobility Data RDW - National Road Transport Agency
On the data portal of open mobility data from the RDW you will find open datasets on the theme of mobility, such as vehicle and parking data. You will also find an overview of applications that have been developed on the basis of this data. The data is free and can be used without reservation. In addition, data sets from other parties in the mobility chain are offered via this platform. You will also find user manuals, tutorials and other resources. The RDW invites everyone to indicate which datasets are required.
NDW - National Road Traffic Data Portal
In the National Road Traffic Data Portal (NDW) Dutch governments work together to collect, combine, store and distribute open mobility data. That means they are freely available for reuse in third-party applications. These data are essential for traffic management, they feed countless traffic information services and form a solid basis for mobility policy in our country.
Our current traffic data and status data are interesting for applications on websites and in applications. By using a data feed, you automatically and continuously feed your site or app with the latest (minute) data.
Historical data from our big data environment are particularly interesting for analysis and research. These concern the intensity, the average speed and the average travel time between two points. Our history goes back to July 2011. For incidental requests you can use our user-friendly basic module. For larger work, there is the expert module.
OldMapsOnline indexes over 400.000 cards. This is only thanks to the archives and libraries that were open to the idea and provided their content online. OldMapsOnline was born out of a love for history and heritage of old maps. The project started as a collaboration between Klokan Technologies GmbH, Switzerland and The Great Britain Historical GIS Project, based at the University of Portsmouth, UK, thanks to funding from JISC. Since January 2013, the project has been improved and maintained by volunteers and the team of Klokan Technologies GmbH in their spare time.

ArcGIS Living Atlas
De ArcGIS Living Atlas ESRI contains a lot of public data for VU students and employees. This data can be loaded directly from ArcGIS Pro (video 2), but is also visible from ArcGIS Online.
The ArcGIS Living Atlas is a comprehensive collection of geographic data from around the world. Data compiled by Esri and many other approved organizations. It contains maps, apps, and data layers to support your own data. ArcGIS Living Atlas contains data from snapshots, but also live data about, for example, the weather or traffic. Use the ArcGIS Living Atlas for a specific purpose or to get inspired!
USGS - United States Geological Survey
De United States Geological Survey is a source of primary and secondary geographic data for GIS applications. There is a lot of satellite data available, but also interpreted data, such as land cover data. The USGS data is presented both spatially and geographically and includes The National Map, Earth Explorer, GloVIS, LandsatLook, and many more. Visit the website and check out the possibilities!
