Calling Sequence

AddPath(m,p1,p2,option)

AddPath(m,ref1,ref2,option)

Parameters

m

-

a WorldMap object

p1,p2

-

a list representing a point

ref1,ref2

-

a Reference to the GeoNames dataset

option

-

(optional) keyword option of the form option=value, where option can be endpoints 

Options

• 

endpoints : truefalse; determines whether or not the two points are added to the list of points that m stores. By default, endpoints is set to true.

Description

• 

The AddPath command inserts a great circle path connecting two points where the path is the shortest route between the two points on the earth's surface.

• 

If p1 and p2 are given, both p1 and p2 must be lists 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.

• 

If ref1 and ref2 are given, both ref1 and ref2 must contain exactly one row, so they each corresponds to exactly one point.
