Datasets free of charge
The National Land Survey of Finland (NLS) has opened some of its datasets to be used free of charge with extensive access rights.

The datasets can be used for private and commercial purposes, be published, further licensed and attached to other products and services.
Digital products
The sources used for providing the National Land Survey’s digital products are the data sets collected in the Topographic database and the Cadastre.

Products can be acquired in desired sizes, either covering the entire country or parts of it (municipality and map sheet).
