Convert between geodetic and rectifying latitudes
RectifyingLatitudeConverter object provides conversion
methods between geodetic and rectifying latitudes for an ellipsoid with a given third
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.
ThirdFlattening — Third flattening of an ellipsoid
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
Create a Rectifying Latitude Converter Object and Set Property
grs80 = referenceEllipsoid('GRS 80'); conv1 = map.geodesy.RectifyingLatitudeConverter; conv1.ThirdFlattening = grs80.ThirdFlattening
conv1 = RectifyingLatitudeConverter with properties: ThirdFlattening: 0.0017
Create a Rectifying Latitude Converter Object, Specifying Spheroid
grs80 = referenceEllipsoid('GRS 80'); conv2 = map.geodesy.RectifyingLatitudeConverter(grs80)
conv2 = RectifyingLatitudeConverter with properties: ThirdFlattening: 0.0017
