Here you can find material about the data set of cultural historical remains. The material is aimed at you who are business developers, administrators within municipalities and authorities, consultants, system suppliers and developers. Together, we create a smarter urban planning and building process.

Cultural historical remains and the National Geodata Platform (NGP)
The dataset contains cultural historical remains that have been registered in the cultural environment register. The National Antiquities Authority (RAÄ) is the producer and, with the support of Lantmäteriet , has produced a national specification. The dataset consists of approximately 740,000 remains and is updated daily.
Cultural-historical remains is a collective term for ancient remains and other cultural-historical remains. Ancient remains are protected according to the Cultural Environment Act. This means that ancient remains are protected even if they have not been discovered or registered previously. Other cultural-historical remains do not meet all the requisites (conditions) of the law, but are nevertheless culturally-historically valuable and must be taken into account.
Geometric quality information
The main part of the information has an uncertain position indication and may therefore be wrong on the map. About 75 percent of the remains are registered as a center point or center line, which does not reflect the actual extent of the remains.
Continuous work is underway to raise the quality and make visible and explain the uncertainty in the location information. Among other things, in connection with the specification work, work has been done to describe geometric quality information about a legacy. Remains geometry describes survey quality of a remains and the likely distribution of point and line objects.
In addition to geometric information and geometric quality data, the following are specified for each cultural historical remains:
- Basic attributes that describe the relic.
- Antiquarian assessment that describes the relic's assessed legal protection.
- Status that describes the condition of a relic in terms of possible damage and its size, as well as the extent to which the relic has been investigated and documented.
- Composite estate that describes an estate that is part of a so-called composite estate.
The type of estate that the estate is deemed to have is based on antiquarian practice. RAÄ's list of types of remains (new window).
The data set is available via APIs
With cultural historical remains in the platform, the data set becomes available in a standardized and harmonized way via modern APIs. To develop a software or solution that uses the platform's APIs, you need to join NGP as a consumer.
Take part in:
• How you as a consumer connect to NGP (new window).
• Technical descriptions for you who are developers (new window).
• More about the data set of cultural historical remains and specifications (new window).
Please note that the information about cultural historical remains is still available at RAÄ:
- via the peephole Fornsok (in Swedish, new window)
- as direct access service and download (shape/geopackage) for use in GIS (in Swedish, new window).
Usage
A large use of the dataset is in planning but also in other applications, such as visualization. When it comes to planning, information about remains is important to protect them but also to take advantage of and highlight cultural environmental values.
Sweco shows a demo of how the dataset of cultural historical remains in NGP can be used (in Swedish).
Some who see a benefit in that the data set is now in NGP are Antonia Baumert, business developer at RAÄ Geographical information and analysis, and Erik Edelönn, GIS manager at Renewable Sweden:
– Thanks to NGP, actors in the community building process can find information collected in the same place and structured in the same way. We believe that the cultural environment information reaches more people in this way. And it provides increased protection for our common cultural heritage, says Antonia Baumert.
- I see very positively that data is collected on a common platform and that the concepts are harmonized. In the future, getting cultural-historical remains from the same place as buildings, detailed plans and national interests means a more efficient use of resources for all parties and contributes to higher quality in our work, says Erik Edelönn.
