)

Arguments

x

A trajectory object

threeD

A boolean indicating whether the plot should be 3D or 2D (default FALSE, 2D).

col

A string corresponding to the color of the line used for 2D trajectory (default "blue4").

col_start

A string corresponding to the color of the point used to denote the beginning of a 2D trajectory (default "green3").

col_end

A string corresponding to the color of the point used to denote the end of a 2D trajectory (default "red2").

pch_points_start

A numeric corresponding to the symbol (pch) of the points used to denote the beginning of a 2D trajectory (default 15).

pch_points_end

A numeric corresponding to the symbol (pch) of the points used to denote the end of a 2D trajectory (default 16).

cex_points

A numeric corresponding to the size (cex) of the points used to denote the beginning and the end of a 2D trajectory (default 1.5).

add_altitude

A boolean to indicate if the altitude should be plotted in 2D trajectory in NED system (default TRUE; altitude is plotted).

n_split

A numeric for the number of ticks in 2D plot with altitude profile, if NULL no ticks are added (default = 6).

plot_end_points

A boolean to indicate if points should be plotted at the beginning and the end of a 2D trajectory (default TRUE; points are plotted).

add_title

A boolean or string. If a boolean is used it indicates if a title should be added to 2D trajectory (only active if name of trajectory exist); if a string is used it corresponds to the title (default TRUE).

threeD_line_width

A numeric corresponding to the width of the line for a 3D trajectory (default 4).

threeD_line_color

A string corresponding to the hex color code of the line used for a 3D trajectory (default "#008080").

threeD_col_grad

A boolean to indicate if a color gradient should be used for a 3D trajectory (default FALSE).

threeD_grad_start

A string corresponding to the hex color code for the start of the gradient (default "#008080").

threeD_grad_end

A string corresponding to the hex color code for the end of the gradient (default "#ab53cf").

...

Additional arguments affecting the plot produced.

Value

A trajectory plot.
