Template:SMS Delineate Mesh Workflow

1. Import elevation raster
Use the File | Open... command to import GIS data files such as Shapefiles, MIF/MID files, Lidar files, or raster files. Alternatively, drag and drop the file into the Graphics Window in SMS.

2. Create map coverage
Select Map Data in the Project Explorer and use the New Coverage right-click command. Use the New Coverage dialog to create a new coverage by selecting the desired coverage type, and naming the coverage.

3. Create an outlet point
Use the Create Feature Node tool to create an outlet point.

4. Run the watershed from raster tool
Open the Toolbox. Open the Watershed from Raster tool. Run the tool.

5. Clean objects

8. Merge Coverages
Select multiple coverages that have feature objects which need to be on the same coverage. Use the Merge Coverages right-click command. Right-click on the new coverage and set the correct coverage type. Use the Clean Options dialog to resolve conflicting feature object data in the new coverage.

9. Set polygon properties

1. Select a polygon and open the 2D Mesh Polygon Properties dialog. Use the Select Poylgon tool to select a polygon. Double-click on the selected polygon or use the Feature Objects | Attributes menu command. 2. Set the Mesh Type, Bathymetry Type, and Material Type for the polygon. Mesh types include Patch, Paving, Scalar Paving Density, and Constant Paving Density. Bathymetry type describes the elevation/topography source for the mesh nodes. Bathymetry types include a constant elevation value, interpolated elevation values from a scatter set, or interpolated elevation values from an existing mesh. Material types can be assigned to a polygon using materials previously created in Materials Data dialog. 3. Preview and edit the polygon mesh. Select the Preview Mesh button. Use the preview tools to edit the mesh. Set Arc Options to adjust distribution of vertices. Use Node Options to change how arcs are treated when using a patch mesh type.

10. Create mesh
Open the Toolbox. Open the UGrid from Coverage Tool Run the tool.
