Hello,
I worte a GRASS module to export raster data in netcdf format, readable
by a wide range of post-processing/visualization packages.
The module exports raster with data models suitable to be read directly
by Generic Mapping Tools as .grd file (-g flag) and IBM Data
Explorer-OpenDX (-d flag). This should give extra opportunities for
high-quality output from GRASS GIS processed data.
The module has been compiled in a grass-5.0.1 env and tested on the spearfish dataset. Obviously it requires netcdf library (available on most GNU/Linux distributions, or dowloadable from http://www.unidata.ucar.edu/packages/netcdf/).
The spearfish sample outputs, and the code together with the manpage can
be found at this URL:
http://www.unipg.it/~afrigeri/r.out.netcdf
Some work has to be done in order to align grass raster and netcdf data
types (TODO), but the module currently is up and working.
I hope this module will be useful to the GRASS GIS community.
I look forward for feedback on this module and testing. After some
feedback it could be posted to the GRASS-user ml.
Thanks to all the developers encouraging newbies.
