Background map series (raster)

The Background map series is a dataset product series in raster format that depicts the whole of Finland and that is meant for web use as a background material for thematic data. Its key objects are road names, roads and railways, buildings and constructions, administrative borders, geographical names, waterways, land use and addresses of buildings (from the Population Register Centre).

The product belongs to the open data of the National Land Survey of Finland. More information: Topographic data and how to acquire it http://www.maanmittauslaitos.fi/en/maps-and-spatial-data/expert-users/topographic-data-and-how-acquire-it.

Purpose:

The Background map series is applicable to be used, for instance, to present the location of features in an online service. The product is applicable to be used at scales ranging from 1:2,500–1:10 million. By completing the dataset with the address road network in vector format and geographic names the user can also compile address-based positioning and route search applications.

Data content

The data content of the Background map series according to background map rasters:

The data content becomes larger as the scale increases. The data content includes objects that are essential when locating your position. The images have been anti-aliased.

Background map raster 1:5,000

The dataset is based on the Topographic databases except for the address numbers of buildings. The key objects are roads (also paths suitable for driving as well as walking and cycling routes), road names, address numbers of buildings (the Population Register Centre), buildings and constructions, railways, geographical names, administrative borders, waterways and land use (e.g. fields, swamps, parks). Background map raster 1:5 000 is the only scale level in the Background map series that includes road names and address numbers of buildings.

Background map raster 1:10,000

The dataset is based on the Topographic database. The key objects are roads (also paths suitable for driving as well as walking and cycling routes), buildings and constructions, railways, geographical names, administrative borders, waterways and land use (e.g. fields, swamps, parks).

Background map raster 1:20,000

The dataset is based on the Topographic database, in addition selection generalisation has been used. The key objects are roads (also paths suitable for driving as well as walking and cycling routes), buildings and constructions, railways, geographical names, administrative borders, waterways and land use (e.g. fields, swamps, parks).

Background map raster 1:40,000

The dataset is based on the dataset Topographic map 1:100,000, in addition selection generalisation has been used. The key objects are roads, railways, geographical names, administrative borders, waterways and land use (e.g. fields, swamps, parks).

Background map raster 1:80,000

The dataset is based on the dataset Topographic map 1:250,000, in addition selection generalisation has been used. The key objects are roads, railways, geographical names, population centres, administrative borders, waterways as well as fields and swamps.

Background map raster 1:160,000

The dataset is based on the dataset Topographic map 1:250,000, in addition selection generalisation has been used. The key objects are roads, railways, geographical names, population centres, administrative borders, waterways as well as fields and swamps.

Background map raster 1:320,000

The dataset is based on the dataset Topographic map 1:1,000,000 and the geographical names in Map names 1:500,000, in addition selection generalisation has been used. The key objects are geographical names, roads, railways, population centres, administrative borders, waterways as well as fields and swamps.

Background map raster 1:800,000

The dataset is based on the dataset Topographic map 1:1,000,000, in addition selection generalisation has been used. The key objects are geographical names, roads, railways, administrative borders, population centres and waterways.

Background map raster 1:2,000,000

The dataset is based on the dataset Topographic map 1:4,500,000. The key objects are geographical names, roads, railways, administrative borders and waterways.

Background map raster 1:4,000,000

The dataset is based on the dataset Topographic map 1:4,500,000, in addition selection generalisation has been used. The key objects are geographical names, roads, railways and waterways.

Background map raster 1:8,000,000

The dataset is based on the dataset Topographic map 1:4,500,000, in addition selection generalisation has been used. The key objects are geographical names, main roads and waterways.

Maintenance

Updating frequency: Background map rasters 1:5,000, 1:10,000, 1:20,000 and geographical names are updated every week. Background map rasters 1:40,000, 1:80,000, 1:160,000, 1:320,000, 1:800,000, 1:2 million, 1:4 million and 1:8 million are updated once a year.

Lineage

The source material used in the Background map series is based on the National Land Survey's map databases at different scales. Regarding positional accuracy, the most accurate scales of the Background map series correspond to the most accurate nationwide map dataset in raster format, i.e. Basic map raster that is based on the Topographic database.

The source data of each background map raster is in most cases an NLS map dataset the scale of which is lower than the nominal scale.

This aims for a portrayal that is as generalised and clear as possible and better suitable for background maps.

The updating frequency varies depending on the feature (see Maintenance).

The positional accuracy of features on the Background map rasters 1:320,000 and 1:800,000 are based on the positional accuracy of General map 1:1,000,000 (approx. 1,000 m).

The positional accuracy of features on the Background map rasters 1:2 million, 1:4 million and 1:8 million are based on the positional accuracy of General map 1:4,500,000 (approx. 5,000 m).

The positional accuracy of the feature in raster data material depends on its pixel size and imaging technology.
