<div id="ygrps-yiv-931261385">Which brings us to the relativity of highest and lowest points (we&#39;re <br/>
pointing aren&#39;t we?). In the Netherlands, NAP is used, and in Germany <br/>
it is NN. But the Belgian benchmark, Oostends Peil (Ostend Level) is <br/>
reportedly 2m and 34cm below these. And other countries use other <br/>
mean sea levels, probably.<br/>
<br/>
How is the height of mountains measured (taking which level as 0 m, I <br/>
mean)? Say that, for example, the &#39;level zero&#39; of Nepal is different <br/>
from that of China, then Mt. Everest has two heights. But I have seen <br/>
more than two on various maps over the years...<br/>
