Data sources for national map products
The most important data sources for creating national map products and services include airborne sensors such as laser scanning, aerial photos, and satellite images, as well as drones. Furthermore, high quality reference data is required, which mainly comes from the National Forest Inventory (NFI) and other inventories as well as specific derived annotations.
Applications in forestry
The products are so-called "Analysis Ready Data" and are used in forestry planning, restoration, forest condition assessment, as well as forest monitoring, and they constitute an important basis for digitalisation.
Collaborations with others
The Swedish Forest Agency collaborate with several research groups and other stakeholders for development and distribution of further map products.
Some of the results are shared through the National Forest Data Lab which is a collaboration platform jointly managed by the Swedish Forest Agency and SLU and developed in cooperation with other stakeholders.
