<div dir="ltr">Hi Rick,<div> The same shapefile works fine with GPM data and wrf output data but only having issue with station data. Please find attached shapefiles. I have attached one plot in which I have used same shapefile for wrf model output and GPM data. Here plots (a,b,c) represents wrf plots and (d) represent GPM data plot and (e) represent station data plot. </div><div><br></div><div>This is the output of ncl_filedump District_Boundary.shp</div><div><br></div><div>Variable: f<br>Type: file<br>filename: District_Boundary<br>path: District_Boundary.shp<br> file global attributes:<br> layer_name : District_Boundary<br> geometry_type : polygon<br> geom_segIndex : 0<br> geom_numSegs : 1<br> segs_xyzIndex : 0<br> segs_numPnts : 1<br> dimensions:<br> geometry = 2<br> segments = 2<br> num_features = 30 // unlimited<br> num_segments = 33<br> num_points = 164066<br> variables:<br> integer geometry ( num_features, geometry )<br><br> integer segments ( num_segments, segments )<br><br> double x ( num_points )<br><br> double y ( num_points )<br><br> double PERIMETER ( num_features )<br><br> double AREA ( num_features )<br><br> int64 ID ( num_features )<br><br> string DIST_NAME ( num_features )<br><br> double SQ_KMS ( num_features )</div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jan 9, 2020 at 4:50 AM Rick Brownrigg <<a href="mailto:brownrig@ucar.edu">brownrig@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Can you either i) provide the shapefile (and I'll point out that means the .shp, .shx, .dbf files), or perhaps show us the results of <br></div><div><br></div><div> ncl_filedump District_Boundary.shp</div><div><br></div><div>Rick</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jan 8, 2020 at 7:24 AM Ajay Bankar via ncl-talk <<a href="mailto:ncl-talk@ucar.edu" target="_blank">ncl-talk@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Dear NCL Users,<div> I'm trying to make spatial plot of rainfall from station data available in csv file.
