Methods documentation

+
+TriaxialEllipsoid.geocentric_radius(longitude, latitude, longitude_semimajor_axis=0.0)[source]#
+

Radial distance from the center of the ellipsoid to its surface.

+

Assumes geocentric spherical latitude and geocentric spherical +longitudes. The geocentric radius is calculated following [Pec1983].

+
+
Parameters
+
    +

  • longitude (float or array) – Longitude coordinates on spherical coordinate system in degrees.

    • +

  • latitude (float or array) – Latitude coordinates on spherical coordinate system in degrees.

    • +

  • longitude_semimajor_axis (float (optional)) – Longitude coordinate of the meridian containing the semi-major axis +on spherical coordinate system in degrees. Optional, default value +is 0.0.

    • +
+
+
Returns
+

geocentric_radius (float or array) – The geocentric radius for the given spherical latitude(s) and +spherical longitude(s) in the same units as the axes of the +ellipsoid.

+
+
+
+

Tip

+

No elevation is taken into account.

+
+

Notes

+

Given geocentric spherical latitude \(\phi\) and geocentric +spherical longitude \(\lambda\), the geocentric surface radius +\(R\) is computed as (see Eq. 1 of [Pec1983])

+
+\[R(\phi, \lambda) = +\frac{ + a \, (1 - f_c) \, (1 - f_b) +}{ + \sqrt{ + 1 + - (2 f_c - f_c^2) \cos^2 \phi + - (2 f_b - f_b^2) \sin^2 \phi + - (1 - f_c)^2 (2 f_b - f_b^2) + \cos^2 \phi \cos^2 (\lambda - \lambda_a) + } +},\]
+

where \(f_c\) is the meridional flattening

+
+\[f_c = \frac{a - c}{a},\]
+

\(f_b\) is the equatorial flattening

+
+\[f_b = \frac{a - b}{a},\]
+

with \(a\), \(b\) and \(c\) being the semi-major, +semi-medium and semi-minor axes of the ellipsoid, and \(\lambda_a\) +being the geocentric spherical longitude of the meridian containing the +semi-major axis.

+

Note that [Pec1983] use geocentric spherical co-latitude, while here +we used geocentric spherical latitude.
