I've just announced my NetCDF tools 0.1-rc1 package [1], and
wonder, is there anyone interested in having it in Debian?
In the nutshell, the package basically provides a somewhat
sophisticated wrapper around the ncvarget () and ncattget ()
functions (provided both by NetCDF and by the HDF4 compatibility
layer), which may be used, in particular, in Shell scripts.
The versions of the `ncget' tool have found occasional uses
here, at Altai State University, during the last three years,
and proved to be quite usable, despite having a few bugs and
misfeatures.
TIA.
* Examples
In particular, this package could be used to visualize MODIS L3
(HDF-EOS ``Grid'' structure) data (thanks to the NetPBM and
ImageMagick packages), like (Bash syntax used):
$ rgb3toppm <(ncget-hdf --raw \
MCD43B4.A2009153.h22v03.005.2009181051526.hdf \
Nadir_Reflectance_Band{1,4,3} \
| rawtopgm -bpp 2 -littleendian \
-maxval 15999 1200 1200) \
| convert -gamma 1.6 ppm:- ppm:- \
| display ppm:-
In this example, the Nadir_Reflectance_Band1, ...4 and ...3
``variables'' (i. e., arrays) of the HDF4 file were fetched and
then converted to the PGM image format. Then, the gamma
correction was applied and the resulting image is shown on an X
display.
