<div dir="ltr"><div dir="ltr"><div>KMZ is a shape format, but it is different than the official ESRI shapefile format.

<br>
I would like to import a shapefile into my NCL code, in order to have the<br>
regional (and possibly provincial) suddivision of Italy.<br>
<br>
First, I tried with the KMZ level-2 "gadm36_ITA_2.kmz" available in<br>
<a href="http://www.gadm.org" rel="noreferrer" target="_blank">www.gadm.org</a>. Once I imported this file into my code, set lnres=True with<br>
its options and typed:<br>
<br>
id = gsn_add_shapefile_polylines(wks,map,"gadm36_ITA_2.kmz",lnres)<br>
<br>
I get this error message:<br>
<br>
warning:_NclOpenFile: Can not open file <gadm36_ITA_2.kmz>; file format<br>
not supported or file is corrupted<br>
warning:isfilevar: undefined file returning missing value<br>
<br>
What does it mean properly? It's the first time I have ever tried this, so<br>
I could get wrong easily.<br>
<br>
Thanks in advance,<br>
Giulio Monte<br>
