Re: ncl_convert2nc with ESRI shapefiles?

Hi,

Shapefiles are indeed generally supported, but such support is
optional to the build (alas, there's no easy way to tell which options
have been enabled -- something that is on our TODO list). Are you
using pre-built binaries (which platform?), or a custom build from
sources?

I'd be interested in seeing the result you get if you use ncl itself
to try to open the shapefile; e.g., cd to the directory where your
shapefile(s) reside, and running NCL interactively, enter something
like:

        f=addfile("./FAF_2005_Jan_day_upmw_diesel.shp","r")
