If you need help converting lat/lon from one datum to
another, see “Table 11: Reference ellipsoid constants” below.
The reference ellipsoid constants tell you the actual size and
shape of the earth, which isn’t a perfect sphere. In the table, “a”
is the distance to the center of the earth outward to the
Equator (defined in meters), and “f” is the flattening (defined as
a dimensionless quantity).
