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. Aerial photographs, scanning data and data provided by other data providers are utilised in updating the Topographic database. The updating is done in close cooperation with the municipalities. Field checks in the terrain are also needed to some extent, mostly as regards the classification of features. The topographic database is used in the production of other map products and in various optimisation tasks. This dataset is derived from the version of the Topographic Database 2010 where the data (and features) are divided according to the map sheet devision ([http://urn.fi/urn:nbn:fi:csc-kata00001000000000000182](http://urn.fi/urn:nbn:fi:csc-kata00001000000000000182)). In this dataset the data in sheets and split features have been merged and the features of any class are available in one file and layer. The feature classes in each layer are documented in Lueminut.txt. A detailed description of the process and the results and the encountered errors are documented in Finnish in Maastotietokanta_2010_gpkg_meta.pdf (Prosessikuvaus).
