[ncl-talk] Issue with reading shapefiles (NCL 6.4.0 only)

[Fabien Paulot]

Hi Rick,

thanks for the very quick reply.
The shape file is too big to be sent by email but you can download it from GADM
http://www.gadm.org/country <http://www.gadm.org/country> (select shapefile as file format).
I know this is a problem for France_adm2.shp
Thanks
Fabien

However, I found one instance where a double field shows up as type "none" on 6.4.0, and is thus unreadable, yet is fine under 6.3.0.  I will look into it right away. I don't suppose you could send me your shapefile as an additional test case?
