GTK’s Mineral Deposit Database Renewed – Extractive Waste Now on a Map
The Geological Survey of Finland (GTK) has renewed the user interface of its mineral deposit database and added information on extractive waste. The new RAKKA interface and the new layers in the map service are publicly available to all users.
GTK’s mineral deposit database brings together comprehensive information on Finland’s mineral deposits, bedrock raw materials, and mining and production data. The dataset has now been expanded to include information on extractive waste and its locations.
Extractive waste integrated into the dataset
Information on extractive waste has also been compiled into a spatial data product, which is available in GTK’s Mineral Deposits and Exploration map service. In addition, the dataset can be downloaded via the Hakku service.
Previously, it was not possible to store data on extractive waste in the mineral deposit database. This extension integrates extractive waste related to mining into the same dataset and improves data availability for, for example, environmental assessments and the circular economy of raw materials.
New interface replaces PDF reports
Alongside the expansion of content, the entire user interface of the mineral deposit database has been renewed. The new RAKKA interface is public and replaces the deposit-specific PDF reports previously used in the map service.
In the map service, each mineral deposit, mine and extractive waste site now includes a direct link to the RAKKA interface, where the data can be examined in more detail.
Based on international recommendations
The collection of extractive waste data and the design of the data model have taken into account European and international recommendations as well as national data collection needs. The data are based on published reports and other public sources, and GTK is responsible for maintaining and updating the database.
The renewal of the user interface, the data collection and the development of data distribution have been carried out as part of the NextGenerationEU-funded project REPower-CEST (Clean Energy System Transition), the Horizon Europe-funded project FutuRaM (Future Availability of Secondary Raw Materials), and GTK’s internally funded project JaloNGFF.
