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 in 2D projections. This option is ignored when visualizing the resulting map in 3D. By default, a point is displayed as a black asterisk.

The DataSets[Builtin][WorldMap][AddPoint] command was introduced in Maple 2017.
