To use QGIS to extract cross sections from your DEM the following method can be used.
<li>Draw your cross sections using the TUFLOW 1d_xs file, be sure to fill in the source column.</li>
<li>Install the QGIS plug-in "profile from line" (note you may also need to install shapely - see [http://osgeo-org.1560.n6.nabble.com/plugin-profile-from-line-td4133320.html http://osgeo-org.1560.n6.nabble.com/plugin-profile-from-line-td4133320.html]).</li>
<li>Run the plugin, it is pretty self explanatory, select your cross sections and dem, choose a suitable sampling interval. </li>
<li> Upon running the plugin, QGIS will add a new points file to the workspace, save this as a .csv. This file will contain the source of every cross section as well as the corresponding chainages and elevations.</li>
<li>To split this data into individual .csv files in a format that TUFLOW can read in, download [[File:XSExtractor.xls]]</li>
<li>Follow the instructions in the spreadsheet, after exporting to individual worksheets use the excel TUFLOW utilities "Export Entire Workbook to csv" to obtain all the cross sections in a TUFLOW format.
