The Wikipedia entry on "Geodetic system" is indeed weak. The
inclusion of half-baked Matlab code is hardly encouraging. In fact,
the version of the page before this was dropped in (on March 1, 2007)
On ECEF vs Geocentric: I welcome a return to original terminology
instead of having a multitude of names for the same thing. I have the
Google version of Bomford (1952 edition). Does he define "Geocentric
Coordinate System"? (I couldn't find it there.) If not, is there
another authoritative reference?
