[ncl-talk] plot shapefile precip data

[Mary Haley]

Andrew,

Can you either provide the data files, or the output from:

ncl_filedump nws_precip_1day_observed_20160221.shp

It's possible that your shapefile has just one feature on it, and if so,
you can technically read the data as a series of 1D arrays, and plot with
something like:

; UNTESTED

f = addfile("nws_precip_1day_observed_20160221.shp","r")
pcp = ndtooned (f->PCP)  ; or whatever it's called
lat = ndtooned(f->y)
lon = ndtooned(f->x)

res = True

res at sfXArray = lon
res at sfYArray = lat
res at gsnAddCyclic = False
res at cnFillOn = True
res at cnFillMode = "RasterFill"

plot = gsn_csm_contour_map(wks,pcp,res)
