Convert between geodetic and authalic latitudes


A ConformalLatitudeConverter object provides conversion methods between geodetic and conformal latitudes for an ellipsoid with a given eccentricity.

The conformal latitude maps an ellipsoid (oblate spheroid) to a sphere while preserving shapes and angles locally. (Curves that meet at a given angle on the ellipsoid meet at the same angle on the sphere.) Use conformal latitudes when implementing conformal map projections on the ellipsoid.


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


expand all

Ellipsoid eccentricity, specifed as a numeric scalar. Eccentricity is in the interval [0, 0.5]. (Eccentricities larger than 0.5 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
