Description

• 

The AddPoint command inserts the point p into m.

• 

p must be a list of either two or three elements. The first element in p is the longitude (x-coordinate in the Geographic projection), and the second element in p is the latitude (y-coordinate in the Geographic projection). The optional third element is a string label for the point.

• 

The longitude must lie in the interval [-180,180], and the latitude must lie in the interval [-90,90].

• 

plotopts specify how each individual point gets displayed. By default, a point is displayed as a black asterisk.
