Conversion between geodetic and geocentric, aka Earth-Centered, Earth-Fixed (ECEF) coordinates transcoded from Karney's C++ Geocentric methods.
Note:
On methods .forward
and .forwar_
, let
v
be a unit vector located at (lat, lon,
h)
. We can express v
as column vectors in one
of two ways, v1
in east, north, up coordinates (where
the components are relative to a local coordinate system at
C(lat0, lon0, h0)
) or as v0
in geocentric
x, y, z
coordinates. Then, v0 = M ⋅
v1 where M
is the rotation matrix.
