This tutorial introduces:
:*[[Check_Files_2d_grd | _grd_check_R]]
Map the Project Folder as a Favourite:
<li>Within the QGIS Browser Panel, right click on 'Favorites' and select 'Add a Directory...'.
<li>Navigate to the '''Module_08''' folder and select it.
Review the check files: <br>
:*'''M08_10m_001_grd_check_R'''▼
:*'''M08_5m_001_grd_check_R'''▼
:*'''M08_2.5m_001_grd_check_R'''▼
<ol>
<li>Open the files, either:
▲::*'''M08_10m_001_grd_check_R'''
▲::*'''M08_5m_001_grd_check_R'''
▲::*'''M08_2.5m_001_grd_check_R'''
:*In File Explorer, navigate to the '''Module_08\TUFLOW\check''' folder, individually drag and drop the 10m, 5m and 2.5m check file databases (e.g. '''M08_5m_001_Check.gpkg''') into the QGIS workspace and select the grd_check_R layer for each.
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>The grd_check is the 2D grid defined by the 2d_code layer and contains a region object for each cell. It is useful to understand how the model is orientated, the cell size in relation to the hydraulic features and where certain calculations occur in the model. In this tutorial, the grid is orientated to align with the downstream road.
<li>Compare the cells, inspect how the smaller cell size picks up topographic features compared with the larger cell size. <br>
