This service answers questions about height for individual points or breakpoints on a line or polygon. The product name in Swedish is Markhöjd Direkt.
About this product
Height values are obtained from the National Elevation Model, which is in the form of a grid with 1 m resolution.
Maintenance and update frequency
The product is continuously updated when the National Elevation Model is updated. Production plans and production status can be found under Plans and outcomes.

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.

Do you want deeper technical information about our geodata products you can read the product documentation.
Our geodata products with API:s require that you have an application or software capable of managing the services. To view real property information or maps directly in your browser, you can use Lantmäteriet's e-services.
Plans and outcomes
The product is based on the National Elevation model. The elevation model is continuously updated using point clouds from aerial laser scanning and aerial image matching.
The production plans below are the underlying plans for the updating. The plans can be changed based on weather and other conditions.
Production status
Production status is updated every day and display information regarding date for data capture and survey technique (laser scanning or image matching) for the National Elevation model.
