%\updatedisclaimer

The OGR Layer Converter plugin adds the ability to convert vector data from one OGR-supported 
vector format to another.\footnotetext{Supported formats may vary according to the installed 
GDAL/OGR package.}
The plugin is very simple to run, and only requires a few parameters to be 
specified before running:

\begin{itemize}
\item \textbf{Source Format/Datset/Layer}: Enter OGR format and path to the vector file to be converted
\item \textbf{Target Format/Datset/Layer}: Enter OGR format and path to the vector output file
\end{itemize}

  icon which appears in the QGIS toolbar menu. The OGR Layer Converter plugin dialog appears as shown in Figure \ref{fig:ogr_converter_dialog}.
  \item Select the OGR-supported format (e.g., \selectstring{ESRI Shapefile}{\ldots}) and the path to the vector input file (e.g., \filename{alaska.shp}) in the Source area.
  \item Select the OGR-supported format (e.g., \selectstring{GML}{\ldots}) and define a path and the vector output filename (e.g., \filename{alaska.gml}) in the Target area.
