style='font-size:10.0pt;font-family:Arial'>I am using shapeLib to parse the
.shp file called ‘country.shp’ that comes with ArcMap and am
getting some odd results.  My application will take the vertex points from
each shape and simply draw them as a polygon on my screen.  The problem,
however, is that many of the shapes have stray lines associated with
them.  For instance, the country France gets drawn, but then a line is
drawn to Corsica and then the island of Corsica is drawn.  I see that both
land masses are part of France, but how can I scrub the data to get rid of that
extra line.  I’ve tried just cutting off one polygon drawn when the
next point is more than 2 degrees away, but then on other parts of the world,
not all the land masses get drawn.  </span></font></p>

plotting in a different position?  The map I’m drawing looks rather
odd.</span></font></p>
