This text is taken from chapter 1 of the public domain resource Geodesy for the Layman at http://www.ngs.noaa.gov/PUBS_LIB/Geodesy4Layman/TR80003A.HTM#ZZ0 -- please Wikify as necessary.
I've been reading Gordon Lauf's Geodesy and Map Projections and some of the information is different. e.g. he has Krassowsky with a major semi axis of 6,378,295 rather than the 6,378,245m quoted here, and a reciprocal flattening of 298.4 rather than the 298.3 quoted here.
Also an issue which particularly concerns me is Lauf's suggestion that in general "the geodesic has an infinite number of windings on the spherical earth", oscillating between a given latitude north and south. WHilst this may be true "in general", I would infer that there are particular examples where this is not the case and relatively short periodicitites of return can be found. Harry Potter.
article name
Since figure of the earth is an expression, shouldn't the name if this article be Figure of the earth? Kingturtle 03:12, 13 Dec 2003 (UTC)
I believe the 245.0, 298.3 values to be the correct ones. 85.76.129.149 20:27, 28 Feb 2005 (UTC)
