Help!  The street (Malmslättsvägen) runs across my house and 
continues out in the middle of the cemetary!  Where is the "edit" 
link?

Part of the error can be explained by the fact that the satellite 
images are taken from the south-east.  You see the south and east 
walls of towers and tall buildings.  If you continue these walls 
down to the sea level (40 metres into the basement), that might be 
where the street is drawn.  The errors that I see are streets 
drawn too far south-east.  I don't know if the streets are wrong 
or if the images are.
