Talk:Bathymetry

From Wikipedia, the free encyclopedia

Up until June of this year, the first line of this page said, "Bathymetry is the underwater equivalent to topography" instead of "Bathymetry is the underwater equivalent to altimetry". For a layman like myself, "topography" provides a much more meaningful comparison. Mendelbob 03:04, 26 October 2006 (UTC)

As far as I am aware, "altimetry" is the measurement of altitude, while "topography" is the shape or structure of the land. But I have frequently heard the word "bathymetry" being used to mean both "underwater topography" and "measurement of depths/ seabed shape". I might have a go at thinking of a more layman-friendly (and hopefully accurate) definition, although I've just spent three hours reviewing/correcting assorted hydrography-related wiki pages, and really need a break now!
