AuthalicLatitudeConverter

Convert between geodetic and authalic latitudes

Description

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

The authalic latitude maps an ellipsoid (oblate spheroid) to a sphere while preserving surface area. Use authalic latitudes when implementing equal area map projections on the ellipsoid.

Creation

You can use the map.geodesy.AuthalicLatitudeConverter function to create an AuthalicLatitudeConverter object.

Properties

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
