<div dir="ltr"><div>Hi Rick,</div><div><br></div>Sorry for the slow follow-up. When I use <b>gsn_add_shapefile_polylines</b>, the map outline looks reasonable. However, when using <b>gsn_add_shapefile_polygons, </b> it only plots the small islands. I get the following error message. Any idea what might be causing this? <span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:small;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">I want to use the high-res Antarctic shapefile to mask out the continent and small islands. </span><div><br></div><div><br><span></span><p class="gmail-p1" style="margin:0px;font-style:normal;font-variant:normal;font-weight:normal;font-stretch:normal;font-size:16px;line-height:normal;font-family:Menlo;color:rgb(0,0,0);background-color:rgb(255,255,255)"><span class="gmail-s1" style="font-variant-ligatures:no-common-ligatures">fatal:MapDataPolygon: ARSCAM - MCS TOO SMALL</span></p>
