geodesic
in geom_segment()
and geom_path()
¶With geodesic=True
a segment will be transformed to a curve representing the shortest path between two points on the surface of Earth.
Note that this parameter only works when functions geom_path()
and geom_segment()
are used in combination with geom_livemap()
.
