How do I open an HDF file in Python?

Reading HDF5 files To open and read data we use the same File method in read mode, r. To see what data is in this file, we can call the keys() method on the file object. We can then grab each dataset we created above using the get method, specifying the name. This returns a HDF5 dataset object.

UPDATE: Here’s the link to the file that I’m working with. Your data are stored as tables rather than gridded (raster) data which could be interpreted by GDAL. It might be easier in the end to work in HDF5 rather than HDF4.

How to read HDF4 data in Python using PANDAS?

Once you’ve got the file in HDF5 (you should not lose any data here as HDF4 attributes translate directly to HDF5) you’ve got a number of options in Python for working with the data. Your best bet is to install PyTables and Pandas and use the inbuilt HDFStore object to read in the data, which might look something like:

Which is the best way to read HDF4 data?

Your best bet is to install PyTables and Pandas and use the inbuilt HDFStore object to read in the data, which might look something like: Printing the store gives you a list of the series and frames stored in the dataset: And from there you’ve got a complete dataframe object where you can do what you like, eg:

Is the HDF4 library compatible with NetCDF?

The HDF4 libraries include an implementation of the netcdf api which can access hdf files. If building with HDF4 and NetCDF it is necessary to build the HDF library with this disabled. If using Ubuntu/Debian? dev packages you must make sure that the libhdf4-alt-dev package is installed instead of the libhdf4-dev package.
