"""Plot the geometries on the basemap using the defined colors
Parameters:
-----------
ax : matplotlib.axis object
An axis object for plots. Overwrites the self.ax attribute.
cmapname : string
Name of the color map from matplotlib (LINK!) (default: 'seismic')
cmap : matplotlib colormap
You can create you own colormap and pass it to the plot.
linewidth : float
Width of the lines.
edgecolor : string, float or iterable
Definition of the edge color. Can be an iterable with a color
definition for each geometry, a string with one color for
all geometries or a float to define one color for all geometries
from the cmap.
facecolor : string, float or iterable
Definition of the face color. See edgecolor.
alpha : float
Level of transparency.
