CL_getEarthMap

Description

• Returns Earth map outlines coordinates (the same maps as used by CL_plot_earthMap()).

  The result is a 3xN matrix (spherical or geodetic coordinates). The third row is initialized to 0 or "er" depending on the type of coordinates ("er" for "sph", 0 for "ell").

  The data consists in continuous segments separated by %nan.

• Notes:

  - Earth map files are loaded from the directory: CL_home()/data/earthMap.

  - The file format is specific to CelestLab.

Parameters

res:

(string, optional) Resolution: "low" or "high". Default is "low".

coord:

(string, optional) Type of coordinates: "sph"=spherical, "ell"=elliptical. Default is "sph".

er:

(optional) Equatorial radius [m]. Default value is [] (internal value used).

pts:

[longitude; latitude; z]; z = "er" if coord="sph", z = 0 if coord="ell". (3xN)

Examples

// Loads a map (spherical coordinates, default radius) pts = CL_getEarthMap(); // Plots the map CL_plot_ephem(CL_co_sph2car(pts));
