=Introduction=
A large number of different file formats are used for storing raster or DEM data. In this page we will use QGIS to convert a format not recognised by TUFLOW into a format used by TUFLOW. In this example a .dem file format is used. However, a large number of formats are supported in the GDAL raster formats, a list is provided here: [http://www.gdal.org/formats_list.html GDAL Raster Formats].
