# CL_plot_earthMap

Plots an Earth map

## Calling Sequence

       CL_plot_earthMap([win_id,color_id,tick_steps,data_bounds,thickness,res,coord])

## Description

- Plots an Earth map in the selected figure (win_id).

  The x-axis and y-axis are respectively the longitude and latitude in degrees.

  Depending on type of coordinates ("coord" option), the longitude is considered to be the spherical or elliptical (geodetic) longitude.

  There are 2 available resolutions:

  - "low": outlines of Earth continents and major islands (low resolution)

  - "high": outlines of Earth continents, islands and lakes

## Parameters

win_id:

  (optional) Figure Id - Id of the current window if omitted.

color_id:

  (optional) Color index - Default is 2.

tick_steps:

  (optional) Steps of the grid in longitude and latitude in degrees. Default is [60 ,30].

data_bounds:

  (optional) Definition of the view area: [longmin, latmin; longmax, latmax] in degrees. Default is [-180, -90; 180, 90].

thickness:

  (optional) Line thickness. Default is 1.

res:

  (optional) (string) Resolution: "low" or "high". Default is "low" (1x1)

coord:

  (optional) (string) Type of coordinates: "sph"=spherical, "ell"=elliptical. Default is "sph" (1x1)

## Examples

    // basic plot
    CL_plot_earthMap();

    // plot in figure 10, with color 2
    CL_plot_earthMap(win_id=10, color_id=2);

    // plot in figure 10, with color 1, and focus on Europe
    CL_plot_earthMap(win_id=10, color_id=1, ..
    data_bounds=[-10,30;40,60], tick_steps=[10,10]);

    // plot in high res, elliptical coordinates and focus on Europe
    CL_plot_earthMap(color_id=5,data_bounds=[-10,30;40,60], ..
    tick_steps=[10,10], res = "high", coord = "ell");
