Package: xseof
xseofOverviewI/O library for the ESA EOF files.This package provides a set of “dataclasses”, comapible with thexsdataPython 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].Project linksHome Page:https://github.com/avalentino/xseofDownload:https://pypi.org/project/xseofInstallationStandard installation viapip:$ pip install xseofInstallation viaconda:$ conda install -c avalentino xseofTestingMove to the the source directory root and run the following command:$ python3 -m pytestBasic usageLoad a generic orbit file:>>> import xseof
