At the date of this document, the following formats are supported by the OGR
library. Formats known to work in QGIS are indicated in \textbf{bold}.

\begin{itemize}
\item \textbf{Arc/Info Binary Coverage}
\item Comma Separated Value (.csv) 
\item DODS/OPeNDAP

\subsection{GDAL Raster Formats}\label{appdx_gdal}
\index{raster layers!supported formats}
\index{GDAL!supported formats}

At the date of this document, the following formats are supported by the GDAL
library. Note that not all of these format may work in QGIS for various
reasons.
For example, some require external commercial libraries. Only those formats
that
have been well tested will appear in the list of file types when loading a
raster into QGIS. Other untested formats can be loaded by selecting the
\textsl{All other files (*)} filter. Formats known to work in QGIS are
indicated
in \textbf{bold}.
