Finnish Topographic Database

The Topographic database is a dataset depicting the terrain of all of Finland. The key objects in the Topographic database are the road network, buildings and constructions, administrative borders, geographic names, land use, waterways and elevation. For DDAS, a set of hydrography-related objects has been selected. This consists of layers: 'Finnish virtavesikapea' (narrow streams), 'Finnish virtavesialue' (rivers as polygons), 'Finnish jarvi' (lakes) and 'Finnish meri' (seas).
