- typhon.geodesy.ellipsoidcurvradius(ellipsoid, lat_gd, azimuth)[source]
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:
