[ncl-talk] convert png to nc file after plot command

[Rick Brownrigg]

Hi,

I don't believe there's a way to do this directly with NCL. However, "gdal"
is a set of utilities that are extremely useful for dealing with geospatial
(raster) data. In particular, the "gdal_translate" command can convert a
png to netCDF. See example 9 at the link below for an example command line
invocation to convert a jpg to netCDF.  Please be advised that gdal has
dozens of optional libraries that can be used to build it, netCDF being
one. The gdal_translate --format" command will list the formats supported
by a given binary.
