The key functions of the MapSite are briefly described here.
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. You can also look up a jointly owned water area with a property identifier, then you can see all the parcels of the water area on the map.
The property identifier can consist of numbers separated by dashes or zeros, e.g. 12-34-5-678 or 01203400050678.
Property and boundary marker information
When you search for a property with the property identifier, the boundaries and boundary markers of the selected property are highlighted on the map. By clicking on a highlighted area or a single boundary marker, you can see more detailed information.
Note that boundary markers are not shown until you zoom in close enough on the map. To view the information about any property, activate cadastral boundaries in the map layer menu and click on a desired property.
If the property consists of more than one area or parcel, all parcels are shown highlighted. Only one property at a time can be highlighted. You can click on the map to change the property to be highlighted. You can take off the highlighting of the property by showing the property information and clicking on "Remove".
The following boundary marker information is shown:
| Number | The number has also been marked on the boundary marker. |
| Structure | A description of what the boundary marker looks like. The boundary marker can be, for instance, a metal pipe or bolt, or a single stone. |
| Location | The boundary marker coordinates are shown in the ETRS-TM35FIN coordinate system. |
| Positional accuracy | Estimated positional accuracy (m). |
| Relationship to ground level | A description of how the boundary marker has been set. The boundary marker can be, for instance, visible or buried in the ground. |
| Existence | Boundary markers are mainly "existing", but in some cases, the boundary marker can also be "missing" or its existence can be "unknown". |
| Source material | The information about boundary markers has been collected from several different sources. The newer the boundary marker information is, the more accurate it is. If the location of the boundary marker has been measured before 2020, the coordinate information shows the following text: "The information has not been confirmed." |

In geographic coordinates, the degree symbol (°) can be replaced by the letter ‘d’.

If you want a printed map, you can choose from basic maps (1:25,000) and topographic maps (1:50,000).
You can select the following content for your own map printout:
- area
- printout size
- scale
- contents, e.g. show property identifiers and boundary markers, grid intersections
You can select weatherproof plastic, canvas or paper as your map printout’s material. The map printout is also available as a PDF file sent by email.
Printed maps and map printouts are delivered by post. For PDF printouts, a download link will be sent to you by email.
Opening and viewing PDF map printouts sent by email
Map printouts are delivered as a download link by email. Click the link and save the file on your computer. The download link is valid for 30 days after placing an order.

Next, open the PDF map printout using Adobe Reader. Click the eye icon in the left-hand menu of the program to select the information you want to be shown on the map.
Download geospatial data
In the MapSite, you can download geospatial data. You can access downloadable data in the right-hand side menu.
Click the dataset you want to make more detailed selections. As a rule, geospatial data software is required to process and open datasets.
Select the product, file format and area. After you have made your selections, add the product to the shopping cart. Downloadable datasets are free of charge.
