Properties

eccentricitySquared

val eccentricitySquared: Double

Computes this ellipsoid's eccentricity squared. The returned value is equivalent to 2*f - f*f, where f is this ellipsoid's flattening.

inverseFlattening

val inverseFlattening: Double

Measure of the ellipsoid's compression. Indicates how much the ellipsoid's semi-minor axis is compressed relative to the semi-major axis. Expressed as 1/f, where f = (a - b) / a, given the semi-major axis a and the semi-minor axis b.

semiMajorAxis

val semiMajorAxis: Double

One half of the ellipsoid's major axis length in meters, which runs through the center to opposite points on the equator.

semiMinorAxis

val semiMinorAxis: Double

Computes this ellipsoid's semi-minor length axis in meters. The semi-minor axis is one half of the ellipsoid's minor axis, which runs through the center to opposite points on the poles.
