In the operations of the National Land Survey, information about property units and housing company shares, as well as information about ownership, mortgages and spatial data are generated and maintained.

In accordance with the principle of the right of access to documents, everyone has the right to access information in public documents and recordings. Such a request for information must, however, be specified in sufficient detail. The National Land Survey has a duty to assist in specifying a request.

This description is published to comply with the demand in accordance with the principle of the right of access and open government by describing how a case is processed, the data that is managed and search terms used in searching for the information. The description also encourages those seeking for information to read more detailed descriptions and instructions on the National Land Survey's website, as well as the opportunties to search for information independently by using our services.

Case management

Cases related to the tasks and operations of the National Land Survey are registered in a Case Register. The Case Register contains information about cases that have been processed or are currently being processed and the stage of processing. Cases processed by the National Land Survey include, for example, cadastral surveys, cases related to registering titles and rights, as well as administrative decisions. Documents, such as applications with appendices, are also attached to the cases.

Information in the Case Register is processed in our case management systems. Cases and adjacent information can be searched using various search terms, such as customer name, property identifier, municipality where the property unit is located, application identifier or cadastral survey number, information in the application or concerning the cadastral survey, and dates pertaining to the processing of the case.

Information about archived cases and attached documents can be looked at and given copies of via the National Land Survey's customer service. Authorities and professional users can browse information in the National Land Survey's archives in the Land Information System (available in Finnish and Swedish).

The National Land Survey is responsible for managing the following data sets pertaining to its statutory tasks: property information, information about housing company shares, map and spatial data, research information and information related to the maintenance of the above-mentioned. Information is processed using maintenance systems. The National Land Survey's data balance sheet  contains a more detailed description of the data and how it is managed, grounds for updating information and the purpose and significance of the data for society.
