Description

Utility to automatically create TUFLOW cross-sections.

Parameters

  1. 1D Network Channel Layer: The layer that will have cross-sections created for it. Cross-sections will be created perpendicular to the lines in this layer. This layer does not need to be a 1d_nwk layer, however if it is, only 'S' and 'G' types will have cross-sections created (blank types are assumed to be 'G' types).
  2. Cross-Section Position:
    1. At Ends: Cross-sections will be created at the ends of each channel.
    2. At Midpoints: Cross-sections will be created at the midpoints of each channel.
  3. Cross-Section Line Length: The length of the cross-section lines to be created (in map units).
  4. Clip Cross-Sections to Layer: If checked, cross-sections will be clipped to the boundary of the polygon layer specified in Clip Layer.
  5. Clip Layer: The polygon layer to clip cross-sections to. Only applicable if Clip Cross-Sections to Layer is checked.
  6. Export Cross-Sections to CSV: If checked, cross-sections will be exported to a CSV file. The CSV files will be created in the same directory as the output file (in a folder called 'csv') if a location is not specified in CSV Output Directory. If checked, the user must either specify a CSV Output Directory or a location for the output layer (cannot be a temporary layer).
  7. CSV Output Directory: The directory to export CSV files to. If left blank, CSV files will be created in the same directory as the output file (in a folder called 'csv').
  8. Elevation Raster: Raster to extract elevations from for CSV output. Must be specified if Export Cross-Sections to CSV is checked.
