<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">I’ve never plotted shapefiles in NCL before, so bear with me. Looking at your code, I would suggest you try using gsn_add_shapefile_polygons like you use gsn_add_shapefile_polylines.
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">Hi all,<u></u><u></u></p>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">I'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've downloaded USA county shapefiles (from "<a href="http://www.gadm.org/country" target="_blank">http://www.gadm.org/country</a>") and SD road network
shapefiles (from "<a href="http://download.geofabrik.de/north-america.html" target="_blank">http://download.geofabrik.de/north-america.html</a>"). 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>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">(0) Error: gsn_add_shapefile_polylines: Can't open shapefile '/home/matt.flournoy/PECAN/overview/July06/new_shp/USA_adm_shp/USA_adm2.shp'<u></u><u></u></p>
<p class="MsoNormal">(0) No shapefile information will be added.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I get the same error if I try inputing the road network shapefile, except that the directory in the first error message is the directory where the road network shapefile is. The
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've attached the code that I'm using, which is very similar to the NCL example online about reading in USA county shapefiles from
the same site as above.<u></u><u></u></p>
