# HDF-EOS Tools and Information Center > This website is the primary source of information for the Hierarchical Data Format - Earth Observing System (HDF-EOS). HDF-EOS is a self-describing file format based on HDF for storing data from NASA's Earth Observing System (EOS) satellites. This site provides access to software, tools, documentation, and other resources for working with HDF-EOS data. ## Software and Tools - [Tools for HDF-EOS Data](https://hdfeos.org/software/): A comprehensive list of software for viewing and analyzing HDF-EOS files. - [HDF-EOS to GeoTIFF Converter (HEG)](https://hdfeos.org/software/heg.php): A tool to convert HDF-EOS swath, grid, and point data to GeoTIFF and other formats. - [HDFView](https://www.hdfgroup.org/solutions/hdfview/): A visual tool for Browse and editing HDF4 and HDF5 files. ## Data and Information - [HDF-EOS Data Formats](https://hdfeos.org/help/reference/): Descriptions of the HDF-EOS2 and HDF-EOS5 data formats. - [HDF-EOS FAQ](https://hdfeos.org/help/faq/): Frequently asked questions about HDF-EOS. ## Code Examples - [HDF-EOS Examples](https://hdfeos.org/zoo/): A collection of code examples in various programming languages for reading and visualizing HDF-EOS data. - [Python Examples](https://hdfeos.org/software/h5py.php): Specific examples for working with HDF-EOS data in Python. - [NCL Examples](https://hdfeos.org/software/ncl.php): Specific examples for working with HDF-EOS data in NCL. - [MATLAB Examples](https://hdfeos.org/examples/matlab.php): Specific examples for working with HDF-EOS data in MATLAB. - [IDL Examples](https://hdfeos.org/examples/idl.php): Specific examples for working with HDF-EOS data in IDL. ## Learning Resources - [HDF-EOS Workshops](https://hdfeos.org/workshops/): Materials and presentations from past HDF-EOS workshops.
