A collaboration between the Dutch Cadastre (Kadaster) and the European Union Agency for Railways (ERA).
Linked data is becoming more important as an integrated way of publishing large-scale governmental datasets. Because linked data is based on open standards, it is possible to utilize the data disclosed in the these datasets across organizational as well as across national borders.
This data story presents insights from the following linked data sources:
- ERA KG, published by ERA, contains information about railway-related objects in the EU.
- Base Registry of Topography (BRT), published by Kadaster, contains information about geospatial objects in The Netherlands. This includes geospatial information about stations and railroads.
The goal of this data story is to explore the similarities and differences between these two linked datasets. The scope of this data story is to take two topics of interest:
- Information about train stations.
- Information about the number of tracks.
1. Stations
The ERA KG contains detailed administrative information about all train stations in the EU. However, the geospatial information about these train stations is relatively simple because only a point geometry is available.
The BRT has detailed polygons for every building in The Netherlands, including station buildings.
Here we see an opportunity to combine information from both sources to deliver a more complete picture.
