Urbanisation continues to be the most profound feature in the development of the societies in Finland, too. This has resulted in a few growth centers in Finland, more effective land use planning and consequent and increasing need for subsurface information for economical and environmentally sound solutions. The development has brought along challenges for surveys that are diverse and not always easily solved. However, tackling the challenges is an important part of the surveys aiming at contributing to the economy and welfare of the societies.
Our presentation discusses the present situation in Finland from the Geological Survey of Finland (GTK) point of view. The geology of Finland is "simple"; Precambrian crystalline bedrock overlain by loose Neogene (Quaternary) glacial sediments such as moraine, sand and gravel, clay and organic peat. It is clear that the demand for subsurface geoinformation and the improvement of the service capability of the GTK has called for major re-engineering of the traditional mapping programmes focused mainly on producing regional 2D information of classical geology. The present development actually covers improvement of the whole chain of data capture from field to end-users, with the following main aims:
1) Optimal 'state of the art' data capture
2) Increased use and development of 3D -methologies both for soil and bedrock
3) Collection of existing data, especially soil drilling data, from various external sources (e.g. environmental authorities, private companies)
4) Development of customer-driven products
5) Easy access to data and products via web -services
A prerequisite for the customer-oriented approach as described above is that it is based on structured geodatabases that incorporate earth material properties relevant for engineering purposes. A national geological datamodel (conceptual level) following largely international development and international standards (classifications, terminologies) will be used in designing the databases. A huge amount of work is still ahead, including testing of best sofwares suitable for 3D modelling and interpretation of geoscientific data for subsurface planning.
