I am using the command 'polyxpoly' to find the intersection of a polygon and a line on a map. I want to know how I can generate this line on the map without using cartesian coordinate system i.e., I want to draw a line from one lon,lat to another and find its intersection with a polygon in terms of lat,lon. How can I draw this line. Pls help.Thanx in advance.
