ellipsoidcurvradius

typhon.geodesy.ellipsoidcurvradius(ellipsoid, lat_gd, azimuth)

Sets ellispoid to local curvature radius

Calculates the curvature radius for the given latitude and azimuth angle, and uses this to set a spherical reference ellipsoid suitable for 1D calculations. The curvature radius is a better local approximation than using the local ellipsoid radius.

For exact result the geodetic latitude shall be used.

Parameters

• lat_gd – Geodetic latitude.

• azimuth – Azimuthal angle (angle from NS plane). If given curvature radii are returned, see above.

Returns

Modified ellipsoid.

Return type
