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.

The RemovePath command removes all paths which connect the two specified end points.

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.

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