Thread: TOPO Sweden Svealand v3 / Friluftskartan Pro v3 - Svealand

A very strange error can be found in the FriluftskartanProv3 Svealand (and also MellerstaSödraNorrlandv3 since the area with the error is covered by both maps). The reading of height is wrong in a limited area of the map. See attached pictures from Mapsource.
On the east side of this valley the readings are correct and on the west side it is far too low, less than one third of the correct.
(And no, I have not "Photoshoped" the screen dumps )

I also managed to find a place where both correct and incorrect values are showed:

The coordinares for this place are N61.99084 E12.87473 for those interested in trying to repeat this

The v2 of the same map does not have the same problem as far as I can see.
I have not digged any deeper in this, but interesting questions are why does the argument for the elevation vector have a faulty value and even a double value?
And I have no idea if this is a common problem or if it is only in this area that it exists, and it would normally not be a problem in the nature. You would certainly know if you are at 300m or 900m, since the trees only grows up to around 850m in this area.
