Barents

The Barents poster is based on the B1000 data. The layers included are: roads, railways, settlements and traffic sites. A vegetation layer is included where vegetated areas are classified as forested areas. Utilities are taken from the DCW data

Roads
All Europavei, Riksvei, Fylkesvei or Lokalvei roads. Private roads are excluded, as are tractor roads and footpaths; roads not maintained in wintertime are also excluded.

Railways
All train tracks on ground or on bridges; tunnels are excluded. All connections points (traffic sites) related to roads/railways/planes/ferries are included.

Settlements
All major cities to villages and smaller populated areas.

Forest
All forest classifications, from high productive forest to taller thicket in the mountains.

Utilities
Power transmission lines, telephone and telegraph lines, over- and underground pipelines are included if they are considered as important landscape features. On the Barents Poster, distances differ between forested and non-forested areas, as forested areas have 4 times less impact  (shorter distance) than bare areas.

Data sources

B1000 is a dataset covering the Barents region. It is a recent project initiated by the regional mapping and land surveying organisations in northern Sweden, Finland, Norway and Russia, collectively called Barents GIT. The data are supposedly up-to-date, and based on the newest available maps in each country. The DCW is a digital cartographic database based on the United States Operational Navigational Chart Series (ONC), scale 1:1,000,000. It was derived from flight charts made for aerial navigation. The data were collected between 1968 - 1989. The DCW was released by the DMA US Defence Mapping Agency in 1992.
