Convert between geodetic and rectifying latitudes


A RectifyingLatitudeConverter object provides conversion methods between geodetic and rectifying latitudes for an ellipsoid with a given third flattening.

The rectifying latitude maps an ellipsoid (oblate spheroid) to a sphere while preserving the distances along the meridians. Rectifying latitudes are used when implementing map projections, such as Equidistant Cylindrical, that preserve such distances.


You can use the map.geodesy.RectifyingLatitudeConverter function to create a RectifyingLatitudeConverter object.


expand all

Third flattening of an ellipsoid, specified as a numeric scalar. ThirdFlattening is in the interval [0, ecc2n(0.5)], or approximately [0, 0.071797]. (Flatter spheroids are possible in theory, but do not occur in practice and are not supported.)

Data Types: double

Object Functions

forward Convert geodetic latitude to authalic, conformal, isometric, or rectifying latitude
inverse Convert authalic, conformal, isometric, or rectifying latitude to geodetic latitude

Introduced in R2013a
