pyrad.graph.plot_pos_map(lat, lon, alt, fname_list, ax=None, fig=None, save_fig=True, sort_altitude='No', dpi=72, alpha=1.0, cb_label='height [m MSL]', titl='Position', xlabel='Lon [Deg]', ylabel='Lat [Deg]', limits=None, vmin=None, vmax=None, lon_step=0.3, lat_step=0.1, background_zoom=8)

plots a trajectory on a map

Parameters:

• lat, lon, alt (float array) – Points coordinates

• fname_list (list of str) – list of names of the files where to store the plot

• fig (Figure) – Figure to add the colorbar to. If none a new figure will be created

• ax (Axis) – Axis to plot on. if fig is None a new axis will be created

• save_fig (bool) – if true save the figure if false it does not close the plot and returns the handle to the figure

• sort_altitude (str) – String indicating whether to sort the altitude data. Can be ‘No’, ‘Lowest_on_top’ or ‘Highest_on_top’

• dpi (int) – Pixel density

• alpha (float) – Transparency

• cb_label (str) – Color bar label

• titl (str) – Plot title

• xlabel, ylabel (str) – The labels of the X and Y axis

• limits (tupple or None) – The limits of the field to plot

• vmin, vmax (float) – The limits of the color scale

• lon_step, lat_step (float) – The step interval of the latitude, longitude lines to plot

• background_zoom (int) – The zoom of the background image. A higher number will give more level of detail at the expense of speed.

Returns:

• fname_list (list of str or)

• fig, ax (tupple) – list of names of the saved plots or handle of the figure an axes
