Without some explanation before hand, I don't think this text makes much sense. I've removed it to make the page a bit simpler, maybe it could be put back with further explanation?
Because orography is spatially averaged, for example the height of the [[Himalaya]] mountains will depend on horizontal [[Image resolution|resolution]]. The higher the horizontal resolution, the better the orography will follow the actual terrain.<ref>[http://amsglossary.allenpress.com/glossary/search?p=1&query=Orography&submit=Search Orography] (from the [[American Meteorological Society]] website)</ref>
