Hi Abdullah,

Let me first say that I agree to a large extent with your reasoning, and I do agree the best course of action is to delete the node. So this is what I will do as a next step.

Leaving a node that is supposed to indicate a region on the Arabian Peninsula located in Egypt, is just nonsense.

Cross checking also with two of my printed "World Atlasses", also confirm your claims about geographical landmarks, as both do not list the "Arabian Desert", while something like the "Rub' al Khali" is.

As to the Wiki: at least the English version may still have some merit to it, in the sense that it clearly states the "Arabian Desert" not as a geographical landmark, but an "eco-region", so a name to indicate a region having a rather uniform and distinct ecological context. So this is different from what we generally consider a landmark.

Whether "eco-regions" like the "Arabian Desert" or "Amazone Forest", or whatever else that could classify as "eco-region", should be mapped in OSM is a different discussion, that I won't go into here now, and as usual, essentially anyone is free to map what he wants in OSM, although the data also stands to be corrected.

Best regards,

Marco
