EPSG:9372 - MML07-IRF

  • United Kingdom (UK) code 9369 (default) [grid]

Selected transformation

Method: NTv2

Grid Files: TN15-ETRS89-to-MML07-IRF.gsb

Remarks: In conjunction with the MML07-TM map projection (code 9370) applied to MML07-IRF (code 9372), emulates the MML07 Snake projection. Applied to ETRS89 (as realized through the OSNet v2009 CORS) defines MML07-IRF hence is errorless.

Revision date: 2020-06-11

Attributes

Unit: metre

Geodetic CRS: ETRS89

Datum: European Terrestrial Reference System 1989 ensemble

Data source: EPSG

Information source: National Land Survey of Finland; http://www.maanmittauslaitos.fi

Revision date: 2020-03-30

Scope: Cadastre, engineering survey, topographic mapping (large scale).

Remarks: Replaces ETRS89 / ETRS-GK22FIN (CRS code 3129). (For medium scale mapping and country-wide work use ETRS89 / TM35FIN(N,E), code 5048).

Area of use: Finland - nominally onshore between 21°30'E and 22°30'E but may be used in adjacent areas if a municipality chooses to use one zone over its whole extent.

Coordinate system: Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
