The service offers you an access to the topographic maps, aerial images and background maps produced by the National Land Survey of Finland. You can search for maps from the whole of Finland by place names and coordinates, among others.  More exact scales also show property boundaries and property identifiers.

MapSite is intended for private persons. It’s accessible to all and free of charge. The use of the service doesn’t require registration.

Through the service you can order various printed map products. Besides topographic and basic maps, you can order map printouts. You can choose the area you want to print out as well as the size and scale of it.

You can also download the Topographic database, laser scanning data, and elevation model as digital files free of charge. The download service has been published as a beta version for the time being, which means that the service is still being developed and tested. During the beta phase, new datasets are also added gradually. More information.

You can download topographic maps and aerial photographs in digital format also from the NLS File service of open data.

On the MapSite, you can have a look at the National Land Survey's maps, aerial photos, and property location data as well as download open datasets.

Detailed product descriptions


Background datasets in the user interface of the MapSite

You can view several map layers on top of each other and by adjusting the transparency of the layers create a customised map view. 

Topographic map

Topographic maps and basic maps are datasets depicting the terrain of all of Finland.

Background map

Background maps use light colours, and they show less data than, for example, topographic maps. The address numbers shown on the background maps are obtained from the Population Information System maintained by the Digital and Population Data Services Agency.

Plain map

This product is particularly intended for people with limited vision, but it also works as a background and guide map. In comparison with the Basic map, the Plain map has less information and fewer colours. The information that is shown has also been emphasised and contrast increased to make map features more easily distinguishable.

Aerial images

Aerial image data is based on aerial photographs taken during data collection for mapping.


Hillshade or shaded relief raster images are greyscale images showing the elevation of the terrain.

Property identifiers and Property boundaries

Property identifiers and boundaries are based on the Cadastre. The property division is approximate. The exact areal dimensions of a property is shown in the cadastral survey documents and the terrain. This data is only available at the most precise scales.

Address data

Address search is based on the road name data in the Topographic database. The search also finds addresses with no buildings. Addresses are address points that have been calculated from the road name data. The location of an address point does not necessarily match the address of a building.

Geographic names

The feature name search is based on the National Land Survey's place name register containing all geographic names on the basic map. There are approx. 800,000 names in the dataset.

Downloadable open datasets in the MapSite (beta)

Topographic database

The dataset depicts 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. 

Laser scanning data 0.5 p

The data refers to three-dimensional point-like data depicting the ground and objects on the ground. It has been spaced out from the original Laser scanning data 5 p to a density of 0.5 points.

Laser scanning data 2008–2019

The data refers to three-dimensional point-like data depicting the ground and objects on the ground. This data has been produced before the national laser scanning programme. The original point density of the data is 0.5 points/m².

Elevation model 2 m

The dataset depicts the elevation of the ground surface, and its grid size is 2 m x 2 m.

MapSite is an information service maintained by the National Land Survey of Finland. It is available at On the MapSite you can, using various search options, browse topographic maps, aerial images and background maps provided by the National Land Survey. In addition, map functions are available for example for measuring distance and converting coordinates. You can order National Land Survey products and download open datasets via MapSite.MapSite is available to everyone free of charge. Using MapSite does not require registration.

Soon you can also download open datasets from the MapSite

In February 2022, the BETA version of the new open data file download service will be published on the MapSite. During the BETA stage, the service will be tested and developed. At the first stage, laser scanning data 0.5 p, laser scanning data 2008–2019, elevation model 2 m, and the topographic database will be available in the service. Datasets will be added to the service gradually. The current open data file download service will operate alongside the new service until all datasets are available in the new service.
