The GPS is right but the GIS is wrong

Leaving Vianden Castle we took the road towards Batogne, in Belgium, to visit the Bastogne Battle Memorial. Our GPS navigator, which we brought with us from Canada, with the most updated map for Europe, took us through a narrow and windy road, covered by a forest and used by crazy bikers and even crazier motor-bikers! Overall enjoyable even though, unlike the motor-bikes, we could not drive fast.

As we were approaching Bastogne, the GPS unit started to indicate a dirty road as the direction to a major landmark! What the heck! Look at the picture and see the road. Now, look to the GPS unit display and you will see the flag indicating the destination. It is not the GPS fault, but an error of the system that manages the positional information. Most likely its databank has this dirty road as paved road. Anyhow, the human interface is still important. LOL.
