Kirkebyggdatabasen is the import of a database of all 1951 churches and chapels in Church of Norway and is owned by "Kirkelig arbeidsgiver- og interesseorganisasjon" (KA). This database also contains additional information information such as a build year, architect, capacity and organisational bodies for each church, but each church is only a node.
Additional data for the building outline of the churches has been sourced from Directorate for Cultural Heritage ("Riksantikvaren") Kulturminne/Enkeltminne-database

- Complete coverage of all churches in Norway. Around 1.000 churches and chapels are not in OSM today and they are important local landmarks.
- Correct names and details for all existing churches.
- Building outline of all churces
Import planning began 2017-12-17. Import may start 2018-02-01.
The import has no schedule and will be imported at the leisure of each contributors.

OSM Data Files
The source data files are available here, please see the original files.
An intermediate OSM file with only data from KA is available here see Churches from Kirkebyggdatabasen (original).osm (as nodes only).
The data is available in OSM and original GML formats.
The final data to be imported is the file Churches.osm
This will be one-time import by the Norwegian OSM community without automated scripts. The 1951 data points will be imported and merged with existing churches with the importers editor of choice.
Data Reduction & Simplification
The data contains 1631 ways (outlines) and 320 nodes and total ~29k nodes so nothing has been done to reduce the data.
The data has been converted from the original database tags to OSM tags.
Some specific tags to this dataset are:
There are 418 "kirkelig fellesråd" in Church of Norway . It is an organisational body which is responsible for administrative matters including maintenance of the churches in its area, usually within one municipality.
The changesets will be marked with the comment: "Kirkebyggdatabasen import of <diocese>" or some other regional area.
The transformations that has been applied to the data is specified in this section.
All nodes are tagged with:
amenity=place_of_worship religion=christian denomination=lutheran
|OSM key||Database attribute|
|building=cathedral||for the dioceses main church, buildings with "dom" in the name|
|building=church||for buildings with "kirke", "kyrkje" etc in the name|
|building=chapel||for buildings with "kapell", "bedehus" etc in the name. Consecrated buildings only.|
|name:xx||Some churches are in Sami administrative area and have a sami name (different xx for different areas of sami)|
|capacity||AntallSitteplasser (SitteplasserOpprinnelig if AntallSitteplasser is empty)|
|wheelchair=yes||RullestolAdkomst contains "Ja"|
|wheelchair=no||RullestolAdkomst contains "Nei"|
|note||Bygningsgruppetype (description of building type)|
A complete church looks like this:
amenity=place_of_worship architect=Christie & Blix building=cathedral capacity=900 deanery=Bergen Domprosti denomination=lutheran diocese=Bjørgvin image=https://www.kirkebyggdatabasen.no/KBDBweb/getPublicImage.aspx?vedleggId=9ACC4690-FC2E-4944-ABB4-551AB028B417 name=Bergen domkirke note=Domkirke operator=Bergen kirkelige fellesråd parish=Bergen domkirke religion=christian start_date=1250 toilets=no
The addresses have been left out as they are a separate (finished) import.
The phone has also been left out as it was not clear who the registered phone number was for.
The architect for 266 churches in the original data was "ukjent" (unknown) and was removed as it did not provide any additional information.
Data Merge Work-flow
The import will be done by the Norwegian OSM community, one diocese at the time.
Some churches have more than one name. The name used on the N50 map will be used in the naExisting geometry me tag; others will be kept in the alt_name tag. Some church names also includes the additional name of the municipality, however, those will be removed from the name of the church.
If a church already has been given a Sami name, both the Sami and Norwegian name will be used plus both names in name:<language>.
Existing building footprints
Some churches already have a building footprint in OpenStreetMap already, and these should be evaluated on a church to church-basis for which to keep and which to replace.
If the geometry is replaced with the new the history should be transfered over, by for example using JOSMs "replace geometry"-function.
Particular care should be given to churches that have a lot of 3D building tags, as the original mapper probably has put a mentionable effort into them. One could replace only the outline of the building in this case.
The steps during the actual import.
Information to include:
- Open Churches.osm in JOSM + "Kartverket N50 topo" background imagery
- Download data from OSM
- Copy your churches to the OSM layer
- Check the following for each church before merging:
- Name: Please check that the new name in the dataset is correct according to Kartverket, including "kyrkje"/"kirke". The official name used by Kartverket should be in name. Alternative names may be kept in alt_name, including the alternative "kyrkje"/kirke" form (useful for searching). Please include "kyrkje"/"kirke" or "kapell" in the name (lower case letters!)
- Building footprint: Please verify that the new building in the dataset is indeed better than the existing building in OSM. If not, transfer the new data attributes only to the existing building.
- 3D: Please take care not to replace an existing building in OSM if it contain 3D features. You recognise 3D tagging through the tags "building:part", "height", "levels" and "roof". Examples: Nidarosdomen, Oslo domkirke.
- You may want to check whether the graveyard around the church has been mapped. Correct tagging is amenity=grave_yard if it is close to the church (so correct if landuse=cemetery has been used).
- Merge the existing node or building with the new node/building using the Replace Geometry function in JOSM. This way the history of the object will be kept. If there are tagging conflicts you will be prompted to resolve them.
- Upload the changeset with the comment "Kirkeimport of <diocese>" with source="Kirkebyggdatabasen and Riksantikvaren" and source:date=2017-11-23.
All churches from the dataset will be conflated with existing churches in OSM one-by-one in a manual process using the To-Do function in JOSM. Position and church names will be verified against the N50 background map.
Please see the conflation section above.
