Tutorial M08 002 GIS Inputs QGIS

Introduction

QGIS is used to create, import and view input data.

Method

Navigate to the Module_08\Tutorial_Data folder. Copy and save all the below layers into the Module_08\TUFLOW\model\gis folder:

• 2d_zsh_M02_landscape_002_L
• 2d_zsh_M02_landscape_002_P
• 2d_zsh_M02_landscape_002_R
• 2d_mat_M02_landscape_002_R

Investigate the supplied files:

1. Open the files, either:
   

   • Drag and drop all .shp files into the QGIS workspace, or
   • Select Layer > Add layer > Add Vector Layer and navigate to the Module_08\TUFLOW\model\gis folder.

2. The 2d_zsh landscape files create a TIN elevation footprint of the development. The 2d_mat file contains polygons that represent the updated land use due to the topography changes. See Module 2 for more information.
   
   
   
   

Conclusion

• Complex development site with TIN functionality was supplied and inspected.
• The 2d_mat layer was reviewed defining the spatial extents for new land use categories.
