\chapter{Data export}\label{sec:USDataExport}

The user must be able to export the following data from \ProgramName:

\begin{itemize}
	\item The calculation log 
	(the log that is produced during the calculations with all errors and warnings provided by kernel validation and calculation) 
	must be saved as text file.
	This needs to be done automatically for every performed calculation.
	In order to keep the files traceable and apart, a time stamp will be incorporated in the filename.
	\item Redesigned surface lines after calculation with characteristic points. 
	The during calculation redesigned surface lines and the corresponding characteristic points must be exported in the same format as the import files. 
	It is a complete set of all calculated locations.
	\item Location scenarios file(s).
	The location scenario data can be exported to a csv file per location.
	\item Calculation result file(s). 
	For stability calculations these are both the sti and the std file as used/produced by D-Geo Stability. 
	For Piping, these are the xml files containing the redesigned surface line and its belonging 1D profile.
	\item Calculation image when available. 
	This is only for stability calculations. 
	The image shows the critical slip plane. 
	In case of design, Adapted geometry, the slip plane will be projected on the adapted geometry.   
\end{itemize}
