Above mean sea level mean[edit]

What is the altitude above mean sea level all earth's lands, together, have? Is there any known answer to this question? It would fit here I think... Undead Herle King (talk) 00:26, 6 September 2009 (UTC)Reply[reply]

Merger proposal[edit]

I propose that this article Height above mean sea level be merged into the Sea level article. Both articles basically cover the same concept, Mean sea level (which at the moment redirects to Sea level). The term 'Height above' is self-explanatory and unnecessary to warrant a separate article (i.e. we do not have, or have need of a Height below mean sea level article).

I think that the content in this article (Height above mean sea level) can easily be moved to Sea Level, and the Sea Level article is of a reasonable size that the merging of Height above mean sea level will not cause any problems as far as article size or undue weight is concerned. -- Marek.69^talk 06:38, 16 May 2013 (UTC)Reply[reply]

What is this map about?[edit]

What exactly is this map about? There is nothing in the article about "vertical references" or "vertical reference systems". Rui ''Gabriel'' Correia (talk) 23:57, 14 September 2013 (UTC)Reply[reply]

About different vertical Geodetic datums / height definitions / height references used troughout Europe. There can be an virtual drop between two countries using different vertical references systems. The Zero-level elevation of Heights above mean sea level is often derived at one point in time from an ever changing main Sea level, but normally not equal to it. --Rknbg (talk) 10:38, 5 October 2013 (UTC)Reply[reply]
