Access rights to other online services and datasets maintained by GTK

GTK’s website features links to other online services and datasets that are maintained by GTK and protected by copyrights, other laws and regulations, as well as agreements. All rights are reserved unless otherwise stated on the website.

Principles of the distribution and pricing of GTK’s content products are described below.

The terms of use for GTK products in online distribution are determined on the basis of GTK’s basic or open licences:

  1. Basic licence
  2. Open licence

The terms and conditions of the basic licence apply to the use of datasets that are available at the website or distributed through the site, unless otherwise stated in conjunction with specific data, or otherwise agreed in writing.

GTK’s open licence complies with the Creative Commons Attribution 4.0 licence. The CC BY 4.0 licence provides the right to copy and distribute GTK’s open access datasets in original or modified format for commercial and non-commercial purposes.

For third-party data included in the service or datasets, the terms and conditions of the copyrights holder apply. An appropriate usage or publication licence is required when reusing these photographs. In this case, the terms of use for photographs follow GTK’s basic licence. Instead, photographs uploaded through the Hakku service are subject to an Open license with a few clarifications: Terms of use for photographs in Hakku service.

Screenshots can be taken on the GTK website, provided that the source is stated clearly.  A separate permission is, however, necessary for any commercial publication.

Disclaimer

The accuracy and other quality factors of GTK’s observation data vary, depending on factors such as the age of the data and the accuracy of base maps, other source material and individual observations, as well as methods of location, modelling, interpretation and production. Geological maps and other datasets include interpreted information and are based on the views of the compiler of the information.

GTK is not responsible for any losses arising from errors or deficiencies in the web distribution system or the datasets, data products or services available on its website. It is recommended that users of data products carefully read the data product descriptions and contact GTK when further information is required. GTK welcomes feedback on its services and data products and will use the feedback to continuously improve its services.
