Technical framework and standard for direct access services

Our direct access services are primarily based on standards from the World Wide Webb Consortium (3WC) och The Open Geospatial Consortium (OGC).

The service interfaces are REST based where object types are in many cases built using GML (Geography Markup Language) or JSON (JavaScript Object Notation) to describe its geographical properties.

The services are of the nature 'question-answer' where the consumer (user's system) sends a service call with search terms or selection parameters over the Internet and receives a list with one or more geographical objects in response.

To quickly get started and test the services before they are integrated into a separate system, a tool such as Postman can be used as a tool for testing REST-based Webservices.

What are you going to do with the information?

How personal data in the Real Property Register may be used is governed by the Real Property Register Act (2000:224) and the General Data Protection Regulation (GDPR). Before we can give you access to personal information in the Real Property register, we must evaluate your purpose with the use, which means that we will ask what you want to do. The application form is available in both Swedish and English.

Forms for evaluation of purpose for extraction-, notification- and download products

Lantmäteriet also reviews all orders from a confidentiality perspective. Confidentiality applies, among other things, to information concerning total defence if it can be assumed to damage the country's defence, or is considered to constitute a danger to national security if the information is disclosed in accordance with 15 kap 2 § Public Access to Information and Secrecy Act (2009:400). The evaluation may therefore in some cases take from three to five working days.
