Introduction

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

Method

Set up the GeoPackage Database:

  1. Navigate to the Module_08\TUFLOW\model\gis folder. Save a copy of M02_001.gpkg as M08_002.gpkg.

Within the QGIS Browser Panel, navigate to the Module_08\Tutorial_Data folder. Drag and drop the following layers from their separate databases into the M08_002.gpkg database:

  • 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:
    • Within the QGIS Browser Panel, navigate to M08_002.gpkg and double click the layers, or
    • In File Explorer, drag and drop the M08_002.gpkg into the QGIS workspace and select the layers (hold Ctrl to select multiple).
  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.
