Detailed Description

Modify polygon so it covers pole correctly.

Modifies a polygon (2D, convex or not) to include pole when passed to inpoly this function is intended to modify a given polygon, so it can be represented in a Cartesian grid the use case is a polygon (e.g. 120,80, -120,80, 0,80 covering the north pole) that is not represented on Cartesian lat-lon grid as polygon. The script inserts additional coordinates, so the pole is covered (e.g. 180,80, 180,90, -180,90, -180,80) See test cases for examples.

Returns

modified coordinates

Parameters

[in]	coord	coordinates of the polygon in question
[in]	meridian_arg	meridian that represents discontinuity, defaults to 180.0
