mittauspisteelle

Mittauspisteelle (literally “measurement point”) is a term widely used in Finnish surveying, civil engineering and construction projects to denote a specific geographic location that has been precisely measured and recorded as a reference point. Each mittauspisteelle is identified by a unique designation, often combining a grid code and an ordinal number, and its coordinates are published in official cartographic documents issued by the Finnish Geospatial Research Institute and the National Land Survey. The designation usually includes information on the vertical datum, with the most common reference system being the Finnish national elevation network tied to the mean sea level.

In practice, a mittauspisteelle serves as a fixed anchor for building foundations, road alignments, hydraulic works and utility installations. Surveyors use portable and permanent instruments such as GNSS receivers and laser levels to establish the exact coordinates, elevations and often the orientation of these points. The data are then incorporated into design drawings and construction plans to ensure that all components align correctly and to provide a basis for future inspections and maintenance.

The establishment of a new mittauspisteelle typically follows a permitting process set by local planning authorities. Once established, the point is documented in the national database and made available to the public through geological and cadastral mapping services. This system ensures consistency in infrastructure development and facilitates the integration of varied projects within the national spatial data infrastructure.
