Jan,
Let me give it a try...
Some results (non-official) of computations for
centers (on the spheroid)
by Jean-Georges AFFHOLDER � IGN - Service de la
Recherche:
CENTRE DE L'EUROPE (g�ographique, de l'Atlantique �
l'Oural et au Caucase)
Latitude : 54� 54' N - Longitude : 25� 19' E.
At the village of PURNU�KES [Lithuania] (� une
vingtaine de km au nord de Vilnius et 180 km de
profondeur).
The institute has made all computations in three
dimensions, on an ellipsoidic cap. The center of the
European area (on this surface) is between the center
of the earth (6200 km) and PURNU�KES (180 km).
EUROPEAN CENTER (geographical, from the Atlantic to
the Urals and the Caucasus)
Latitude : 54� 54' N - Longitude : 25� 19' E.
At the village of PURNU�KES [Lithuania] (tewnty-odd km
north of Vilnius and 180 km deep).

CENTRE DES TERRES �MERG�ES -
Longitude : 29� 00' Est M.I. Latitude : 44� 30' Nord.
en Mer Noire, au large de la ville de HISTRIA
(Istria), Roumanie. [En fait, le centre de gravit� est
situ� � 4200 km de profondeur]
CENTER OF THE EMERGENT LANDS (I assume this means
disregarding depth)
Longitude : 29� 00' E, M.I. Latitude : 44� 30' N.
in the Black Sea, off of the town of HISTRIA (Istria),
Romania. [In fact, the gravitational center is located
4200 km down]
CENTRE OF THE EUROPEAN UNION
Latitude : 50� 00' 33" N - Longitude : 4� 39' 59" E.
Commune de VIROINVAL [Belgique], pr�s du bourg de
Oignies-en-Thi�rache, � 1,3 km au nord de la fronti�re
fran�aise.
CENTER OF THE EUROPEAN UNION
Latitude : 50� 00' 33" N - Longitude : 4� 39' 59" E.
Community of VIROINVAL [Belgium], near the city of
Oignies-en-Thi�rache, 1.3 km north of the French border.
