EPSG:3861

Finland Gauss-Kruger zone 20

Attributes

Data source: EPSG

Information source: National Land Survey of Finland.

Revision date: 2010-04-23

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

Remarks: Replaces Finland ETRS-GK20 (proj code 18184).

Method: Transverse Mercator

Area of use: Finland - nominally onshore between 19°30'E and 20°30'E but may be used in adjacent areas if a municipality chooses to use one zone over its whole extent.
