[ncl-talk] Using merged shapefiles to create PRISM data subset

[Toni Klemm]

Hello All,

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. However, the data subset doesn't look anything like the shapefile (see the Panoply screenshot). I attached the shapefile as GIS files and screenshot. 

My guess is that NCL gets confused about the disconnected-yet-combined counties and doesn't know how to process a shapefile like that. Does anyone know what I can do to make this work? Can I manipulate the shapefile data in QGIS somehow so NCL understands it? Alternatively I could process each county by itself and then average the results. But there are over 100 counties, which would take a very long time. 

I appreciate any help!

Thank you very much,
Toni
