DataSets[Builtin][WorldMap]

 insert a list of points all at once into a WorldMap object Calling Sequence AddPoints(m,ref) AddPoints(m,plist) Parameters

 m - a WorldMap object ref - a Reference to the GeoNames dataset plist - a nested list representing a list of points plotopts - (optional) plot options for all points in plist Description

 • The AddPoints command bulk inserts points into m.
 • If ref is given, all points in ref get inserted into m.
 • If plist is given, each point in plist must be a list of either two or three elements. The first element is the longitude (x-coordinate in the Geographic projection), and the second element 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].
 • If you want to insert multiple points into a WorldMap object, it is more efficient to use AddPoints than calling AddPoint multiple times for the same functionality.
 • plotopts specify how all points in plist get displayed. By default, all points are displayed as black asterisks. Examples
