The initial step in selecting open datasets to use is finding which datasets are available.
Open data are available from different kinds of sources, including government agencies, municipalities, companies, other organizations, and from crowd-sourcing.
Where to start looking
A good starting point to locate datasets is in open data catalogues and portals.
In Norway, the following catalogues and portals are good soures:
- Norway’s official catalog for open data from public sector
- National Data Dictionary - Felles datakatalog
- Geonorge - national site for map data
- Urbalurba’s portal for Norwegian smart city data
Open data from Norwegian municipalities can be found in various catalogues, such as portals provided by the municipalities themselves, the Geonorge portal and Felles datakatalog. The following table gives some examples from the ten largest municipalities in Norway.
|Municipality||Geonorge||Felles datakatalog||Other portals|
|Oslo||Map data||Felles datakatalog|
|Bergen||Map data||Felles datakatalog|
|Trondheim||Map data||Felles datakatalog||Other|
|Stavanger||Map data||Felles datakatalog||Own portal|
|Fredrikstad||Map data||Smart Fredrikstad|
|Tromsø||Map data||Felles datakatalog||Tromsø kommune åpne kartdata|
As datasets can be registered in more than one catalogue, and the catalogues also harvest data from each other. Thus, there is substantial overlap in the catalogues mentioned above.
- European Data Portal
- INSPIRE Geoportal for European spatial data
- UK open government data
- US open government data
- Google Dataset Search (Beta)
Unfortunately, the catalogues do not cover all available data. If you do not find a specific data set, it can still be worth to search for the data in other ways (e.g. through regular Google searches, or by visiting the web pages or contacting the organization you are looking for data from).
