 Similar to how you are attempting to add the road polylines, try to add the polygons in this way as well?? The map you are calling in the create_SD_map function you have defined doesn’t draw these as far as I can tell.

<p class="MsoNormal">I&#39;m trying to plot a simple map of a few counties and roads in South Dakota using NCL 6.3.0. To do this, I&#39;ve downloaded USA county shapefiles (from &quot;<a href="http://www.gadm.org/country" target="_blank">http://www.gadm.org/country</a>&quot;) and SD road network
 shapefiles (from &quot;<a href="http://download.geofabrik.de/north-america.html" target="_blank">http://download.geofabrik.de/north-america.html</a>&quot;). Then, I use gsn_add_shapefile_polylines to add the USA counties to an existing map in my code, but I get this error message:<u></u><u></u></p>

 map is plotted when I run the code, but the shapefile information is not on them.<u></u><u></u></p>
<p class="MsoNormal">Does anyone know what may be causing this issue? I&#39;ve attached the code that I&#39;m using, which is very similar to the NCL example online about reading in USA county shapefiles from
