Review the check files:
<ol>
<li>OpenNavigate the following files fromto the '''Module_04\TUFLOW\check''' folder: and open the '''M04_5m_001_DEM_Z.tif''' layer into QGIS.
<li>Drag and drop the '''M04_5m_001_Check.gpkg''' from the '''Module_04\TUFLOW\check''' folder into QGIS.
*'''M04_5m_001_DEM_Z.tif'''
<li>Open the following layers into QGIS (hold Ctrl to select multiple):
*'''M04_5m_001_zsh_zpt_check_P.shp'''
:*'''M02_5m_001_grd_check_R'''
*'''M04_5m_001_lfcsh_uvpt_check_P.shp'''
:*'''M02_5m_001_zsh_zpt_check_P'''
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Use the 'Apply GPKG Layer Names'.
<li>The DEM_Z grid shows the final elevations used for the model calculations. Change the styling and inspect the area of the embankment is lowered. See <u>[[Tutorial_M02_001_Check_Files_QGISTutorial_M02_001_Check_Files_QGIS_GPKG | Module 2]]</u> for more information on how to review topographic modifications. Note: The DEM_Z appears different to the input DEM as the resolution of the DEM_Z is coarser (2.5m) than the input file (0.5m).<br>
<li>The zsh_zpt_check file displays the elevation points changed by Z shape topographic update and the TUFLOW styling provides an indication of the elevation difference.<br>
