I have adjusted the size of the overlay based on known paper size. The adjusted coordinates are off by 30-50 metres to the coordinates posted by Eugenius earlier. Based on how one draws, interprets and measures the centre of the symbols on the overlays, the coordinates can change some 10-15 metres any direction. The adjusted approximate WGS84 coordinates from karjalankartat.fi are as follows:Eugenius wrote: ↑04 Apr 2021, 01:54The easiest explanation is that Finnish soldiers had no GPS positioning devices to define actual co-ordinates of the objects. More realistic would be to understand that the maps and positioning capabilities of those times were far less accurate than those we have now.
