HDF Tools is a wrapper for the file handling functionality in pyhdf and and PyTables. It provides a single interface to read, create, and append any HDF file regardless of its format: HDF4, HDF5, or HDF-EOS.
It is most useful for earth scientists who want to use a simple function call to handle data files from multiple sources. Typical usage
often looks like this:
#!/usr/bin/env python
from hdftools import opnenhdf
file = openhdf(filename)
HDF Tools relies on having the HDF4 and HDF5 libraries, as well as the pyhdf and PyTables packages installed. Below are instructions for downloading the most current versions (as of the date of this publcation) of these libraries and packages on Mac OSx. Please see the deverloper websites for instruction for other platforms or versions.
