15-612 The Second Step: Polynomial Representation of Conformal Coordinates in the Second
Strip Replaced by the Conformal Coordinates in the First Strip
The standard polynomial representation of conformal coordinates of type Gauss-Krueger or UTM
in the L 02 -strip is given by ( 15.117 )and( 15.118 ) subject to the longitude/latitude differences
l 2 := L
B 02 with respect to the longitude L 02 of the reference meridian and
the latitude B 02 of the reference point
L 02 and b 2 := B
{
L 02 ,B 02
}
of series expansion.
x 1 = ρ ( x 10 l 2 + x 11 l 2 b 2 + x 30 l 2 + x 12 l 2 b 2 +O 4 x ) .
Easting :
(15.117)
y 1 = ρ ( y 0 + y 01 b 2 + y 20 l 2 + y 02 b 2 + y 21 l 2 b 2 + y 03 b 2 +O 4 y ) .
Northing :
(15.118)
y 0 denotes the length of the meridian arc from zero ellipsoidal latitude to the ellipsoidal latitude
B 02 of the reference point
{
L 02 ,B 02
}
chosen by the identity B 01 = B 02 = B 0 for operational
reasons. The coecients
can be taken from Boxes 15.4 and 15.5 . In addition, the optimal
dilatation factor ρ has been set identical in the L 01 -strip and the L 02 -strip of the same strip width.
The longitude/latitude differences
{
x ij ,y ij }
{
l 1 ,b 1
}
as well as
{
l 2 ,b 2
}
are related by l 2 =( L 01
L 02 )+ l 1
B 02 )+ b 1 being derived from the invariance L = L 01 + l 1 = L 02 + l 2 and
B = B 01 + b 1 = B 02 + b 2 . Now we are on duty to replace
and b 2 =( B 01
L 02 )+ l 1
and b 2 =( B 01 −B 02 )+ b 1 by { ( L 01 −L 02 )+ l 1 ,b 1 } within ( 15.117 )and( 15.118 ), which leads us to
{
l 2 ,b 2
}
by means of l 2 =( L 01
x 2 = ρ [ x 10 ( L 01 − L 02 )+ x 10 l 1 + x 11 ( L 01 − L 02 ) b 1 + x 11 l 1 b 1
