Convert between geodetic and isometric latitudes


An IsometricLatitudeConverter object provides conversion methods between geodetic and isometric latitudes for an ellipsoid with a given eccentricity.

The isometric latitude is a nonlinear function of the geodetic latitude that is directly proportional to the spacing of parallels, relative to the Equator, in an ellipsoidal Mercator projection. It is a dimensionless quantity and, unlike other types of auxiliary latitude, the isometric latitude is not angle-valued. It equals Inf at the north pole and -Inf at the south pole.


You can use the map.geodesy.IsometricLatitudeConverter function to create an IsometricLatitudeConverter 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
