=====
Overview
--------
I/O library for the ESA EOF files.
This package provides a set of "dataclasses", comapible with the
xsdata_ Python library, to access and make I/O operation on the XML files
in the ESA Earth Observation Ground Segment File Format (EOF) [1]_.
In particular, this package supports all the XML based orbit and attitude
products described in [1]_.

https://pypi.org/project/xseof
Installation
------------
Standard installation via pip_::
$ pip install xseof
Installation via conda_::
$ conda install -c avalentino xseof
Testing
-------
Move to the the source directory root and run the following command::
$ python3 -m pytest
Basic usage
-----------
Load a generic orbit file::
>>> import xseof
>>> orbit = xseof.load(
"MA1_TEST_AUX_ORBRES_20210610T045753_20210610T065853_0001.EOF")
Access and print loaded data::
>>> import pprint
>>> orbit.earth_observation_header.fixed_header.notes = ""
>>> pprint.pprint(orbit.earth_observation_header.fixed_header)
FixedHeaderType(
file_name='MA1_TEST_AUX_ORBRES_20210610T045753_20210610T065853_0001',

Load an EOF file of a specific type::
>>> from xseof import int_attref
>>> quaternions = int_attref.load(
"MA1_TEST_INT_ATTREF_20210610T045753_20210610T065853_0001.EOF")
Load data form string::
>>> from xseof import aux_orbres
>>> filename = "MA1_TEST_AUX_ORBRES_20210610T045753_20210610T065853_0001.EOF"
>>> with open(filename) as fd:
... data = fd.read()
>>> orbit = aux_orbres.from_string(data)
