Description

Documentation on TUFLOW Wiki This tool acts as an alternative method to using the native "MERGE" functionality in TUFLOW for 2d_zsh polygons by explicitly assigning elevation points (in a 2d_zsh template) along the polygon perimeter. It is recommended to use this tool for Quadtree models, rather than the "MERGE" functionality, where the 2d_zsh input crosses Quadtree nesting levels. It is recommended to prefix the output layer names with '2d_zsh'.

Parameters

  1. Polygon Layer: The polygon layer that will have elevation points created for it.
  2. Raster Layer: The raster (DEM) layer that will be used to determine the elevations of the output points.
  3. Vertex Distribution Option: Determines how the vertices will be distributed along the polygon perimeter.
  4. Vertex Interval (only used for Densify): The length of the interval between the vertices to be created (in map units). This value should be set to the smaller of the following:
