the International Conference of Geodesy and Geophysics
which conferred in Madrid, adopted the Hayford ellipsoid as
the new standard. The Belgians adopted this new reference
ellipsoid for their new Belgian Datum of 1927 with the origin
altered to the astronomical values of Lommel Signal at: Φ
o
=
51
o
10´ 08.092˝ North, Λ
o
= 04
o
22´ 05.91˝ West of Greenwich.
The azimuth was from Lommel Signal to Lommel Turm: α
o
= 186
o
58´ 47.05˝. During WWII, the connection between the
New Triangulation of France (NTF) Datum and the Belgian
Datum of 1927 was accomplished in 1940 by considering the
geodetic differences in longitude. The longitude difference
between the meridians of Brussels and Paris, as determined
by a comparison of the two triangulations through Mont
Kemmel, gave the geodetic longitude of Brussels as 04
o
22´ 12.7˝. The observed astronomical difference between
Brussels and Greenwich was not used. This discrepancy was
one of the major factors that prompted the recomputation
of all geodetic control in Western Europe after the war.
The Bonne Grid “New Convention” is also referred to as
the “Orange Report Net Grid” and was used through WWII
until 1950.
After WWII, the Kingdom of Belgium adopted the Lambert
Conformal Conic Projection and defined the new grid such
that the False Easting = 150 km and the False Northing =
5,400 km at latitude 50
o
30´ North. The Belgian Lambert
“KM” Grid had a Northern Standard Parallel of (
f
N
) = 51
o
10´ North, a Southern Standard Parallel of (
f
S
) = 49
o
50´
North, and a Central Meridian (
l
o
) = 4
o
22´ 04.71˝ West of
Greenwich. Note that the Belgians defined their Lambert
Zone with two standard parallels, which is the definition
method favored by the French and the Americans. The
British prefer to use a Latitude at Origin (
f
o
) and a Scale
Fact or at Origin (
f
o
). The two methods of zone definition
use slightly different formulae to produce the identical
projection in most cases.
