Abstract

Geological Survey of Finland has mapped surficial Quatemary deposits mainly at a scale 1:20000. These large scale maps cover only part of Finland. To fulfil the needs of the customers and the authorities a new mapping program begin in 2003 to produce maps and database at scale 1:250 000, covering whole Finland by the year 2007. The new database will contain geospatial distribution of sediment polygons and related attribute information. It will be produced by interpreting, modifying and generalising existing spatial data using GIS- and image processing techniques with minimum amount of field work (Nevalainen et al., 2002).
