Usually the shapefiles we see have several features and several segments for each feature. Your shapefile is a little unusual, but not unheard of. Unfortunately, the examples we have all do the averaging across shapefile *features* and not shapefile *segments*.</div><div class="gmail_default" style="font-size: small;"><br class=""></div><div class="gmail_default" style="font-size: small;">This doesn't mean you can't do it with NCL. See the attached plot, where I contoured some dummy 2D data over the area of interest and then generated a second plot where the values were averaged based on whether they fell inside one of these segments. Is this what you are trying to accomplish? If so, I'll clean up the code and send it to you.</div><div class="gmail_default" style="font-size: small;"><br class=""></div><div class="gmail_default" style="font-size: small;">--Mary</div></div><br style="caret-color: rgb(0, 0, 0); font-family: Calibri; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class=""><div class="gmail_quote" style="caret-color: rgb(0, 0, 0); font-family: Calibri; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"><div dir="ltr" class="">On Wed, Dec 19, 2018 at 1:26 PM Toni Klemm <<a href="mailto:toni-klemm@tamu.edu" class="">toni-klemm@tamu.edu</a>> wrote:<br class=""></div><blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left-width: 1px; border-left-style: solid; border-left-color: rgb(204, 204, 204); padding-left: 1ex;"><div style="overflow-wrap: break-word;" class="">Hello All,<div class=""><br class=""></div><div class="">I am trying to use a shapefile of merged counties in the western Great Plains to create a spatial subset of temperature and precipitation data and calculate averages and totals for those counties as a whole.
