What coordinate system is this? With label 'North' and 'East'. All the data point lies in Southern Finland. I tried UTM and http://projfinder.com/. Couldn't figure out...

  • What is the data supposed to represent? Trees? Villages? Lakes? Archeological finds?

    Then get back to whoever gave you the data and ask them?

    Can it be a local system created by surveyors for specific area? May 11 at 13:07

    If you can find/learn the origin of the coordinates, you may convert them into another coordinate system. May 11 at 13:16

    I guess the data are in EPSG code series 2391-2394. The first coordinate of Easting defines the KKJ zone number - 1xxxxxx ->Zone 1 -> EPSG:2391. Both N and E coordinates should have 7 numbers for full meters. Widen the coordinate fields in Excel. The green corner in the cells may mean that numbers are stored as text. Hover on top of a cell and you should see some message.

I think they may be in EPSG::3067, ETRS89 / TM35FIN(E,N), with truncated values. The first coordinate pair (in E,N) may actually be 420000, 7190000.

The GKFINxx zones don't cover enough zones to match with either the easting or the northing data (in case the columns were labeled incorrectly) so I don't think it can be one of those.

As user30184 suggested, they also could be in KKJ zone 3 / Unified coordinate system (EPSG::2393).

    Thank you! It IS truncated numbers and now I can have them on my GIS map properly! : )))
