Line 1: == Introduction == This tool acts as an alternative method to using the native "MERGE" functionality in TUFLOW for 2d_zsh polygons. The TUFLOW Z shape merge option obtains elevations by triangulation of the Zpt values (Zc, Zu, Zv and Zh) not the DEM triangulation, as outlined in the <u>[https://docs.tuflow.com/classic-hpc/manual/latest/ TUFLOW Manual]</u>. This processing tool allows the user to explicitly ~~assigning~~assign elevation points from a DEM layer (in a 2d_zsh template) along the polygon perimeter.<br> It is recommended to use this tool for Quadtree models, rather than the "MERGE" functionality, where the 2d_zsh input crosses Quadtree nesting levels.<br>
