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

This service contains up-to-date maps, aerial photos and property boundaries covering all of Finland. You can view several map layers on top of each other and by adjusting the transparency of the layers create a customised map view.

Map data on the MapSite

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

Detailed product descriptions


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. This data is only available at the most precise scales.


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.

Tips for using the MapSite

Using the map

Search for a feature by place name, address or property identifier

You can add the asterisk (*) to the beginning, middle or end of your search word. The search also displays the number of features found (at most 500).

Use the name or address search to identify a property identifier, for example. Once you have found the correct place, select property identifiers under map layers. 

Search for a feature by property identifier to identify the location of a specific property.

The property identifier can consist of numbers separated by dashes or zeros, e.g. 12-34-5-678 or 01203400050678.

Map view

Print the map view by clicking the printer icon in the top right corner. If a notification is shown at the top of the map view, you can close the notification by clicking X to view the printer icon.
