Eduardo,
Like many file formats they can have a variety of applications and they are
both quite general purpose formats. However, a brief answer closing over
complexities might be something like:
HDF - Primariliy used by NASA for distribution of various satellite data
products. It is a complex and featureful format.
netCDF - Primarily in GDAL so we can easily export data in a form directly
usable in the GMT package. The format is actually very general (not just
for raster data) but we only produce and consume a very specific profile
used in GMT for raster data.
Best regards,
