Saving and Importing a Profile Plot
1. Save a plot file in SMS.
|
- There are two ways to save a plot file in SMS:
1. Save the whole project with the plot dialog open.
|
- With the plot dialog open, use the Save or the File|Save As... command.
- If this version of the project is opened again, the plot dialog will open with it.
|
2. Save the plot separately.
|
- A separate plot file can be created that can be imported into any project with the same mesh.
- Make sure that the desired dataset is selected and therefore represented in the plot dialog.
- With the plot open, use the File|Save As... command to open the Save As dialog.
- Name the file and select "Plot File (*.plt)" next to Save as type.
- Save the file.
|
|
2. Import the plot file.
|
1. Open a project file saved with a plot file
|
- Use the File|Open command to open the project with the saved plot file in it.
- The plot will appear with the project as you open it.
|
2. Import a plot file saved separately
|
- If a plot file has been saved separately, it can be imported into another project with the same mesh and datasets with the same name. A profile plot will also require an observation coverage with the same name. The data in the plot will represent the conditions in that project. To import it:
- Ensure that the open project has all required components to support the plot as described above.
- Use the File|Open command to open the Open dialog and navigate to where the plot file is saved.
- Open and review the plot.

Plot Data
1. Create a plot data coverage.
|
- Create a new coverage with the "Plot Data" type. This coverage type is used in conjunction with the observation coverage to show where a structure will appear on a profile plot created with data from the observation 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.
|
2. Create polygons in the plot data coverage.
|
- It is important that they overlap with observations arcs from the observation coverage.
1. Create enclosed arcs for polygon area.
|
1. Create feature arcs, nodes and vertices.
|
- In the Map module, create feature objects in the active coverage.
- Use the Create Feature Arc tool to create arcs in the map coverage.
- Begin creating a new arc by clicking in the Graphics Window at either arc end. If clicking on an existing feature node, vertex or arc, the new arc will snap to that object.
- Double-click or press the Enter key to terminate the arc.
- Use the Create Feature Node tool to create additional nodes alone or to split arcs.
|
2. Modify arcs.
|
- Feature arcs often need to be edited after initial creation.
3. Split arcs.
|
- An existing arc can be split by:
2. Add a node the arc.
|
- Use the Create Feature Node tool to add a node on an arc in order to split it into two arcs.
|
3. Add a new connecting arc.
|
- Use the Create Feature Arc tool to start or end a new arc on an existing arc to split the existing arc into two arcs.
|
|
4. Merge arcs.
|
- Two arcs that share an end node can be merged together.
- Select the shared node using the Select Feature Node tool.
- Right-click on the node and select the Convert to Vertex command to merge the arcs.
- If desired, the Select Feature Vertex tool can be used to select and delete the new vertex.
|

|
Raster to Flood Depth
1. Use raster to calculate flood depths.
|
- This requires an elevations raster and a water surface elevation dataset.
- Right-click on the raster to be used for the flood depths and use the command Convert to|Flood Depths.
- Next to Geometry, select the desired geometry.
- Next to WSE dataset, selet the desired dataset.
- After the tool has finished processing, change the File name as desired in the Save As dialog.
|
Interpolating from Multiple Elevation Sources Workflow
1. Import elevation sources.
|
1. Import rasters.
|
- Raster data is imported into the GIS module in SMS.
- Use the Open command to import raster data files such as DEMs, KMZ files, and gridded elevation formats.
- Files can also be imported with the "drag and drop" option.
|
|
3. Interpolate raster elevation to geometry to create new elevation dataset.
|
- The Interpolate Priority Rasters tool allows for multiple rasters to be used when interpolating onto a geometry. To do so, follow these steps:
1. Use the Interpolate Priority Rasters tool to interpolate raster data onto the desired geometry.
|
- From the Toolbox, select Interpolate Priority Rasters
- Select the geometry to interpolate onto.
- Select the order of priority for the rasters that will be used for interpolation. The order determines which raster the program will look at first to interpolate data onto the geometry.
- Run the Interpolate Priority Rasters tool.
|
2. Review the data on the geometry.
|
- Turn off all rasters.
- Turn on the desired geometry.
- Adjust the Display Options .
|
|
4. Set the map elevation dataset to the newly created dataset.
|
- While in the appropriate module for the geometry, use the Data|Map elevation... command.
- Select the newly created dataset.
- Adjust the display as desired to review the change in mapped dataset.
|
Discarded workflow components
Set unassigned node values.
|
- Depending on the rasters used, it's possible that some mesh nodes didn't get assigned elevation values. To assign them values, follow these steps:
- Right-click on the mesh in the Project Explorer and use the Mesh → 2D Scatter command.
- Select all desired scatter points. ??Include more information on how to do this?
- Delete the selected scatter points and use the Triangles|Triangulate command.
- After switching to the Mesh module, select all nodes with unassigned values in the grid.
- In the Graphics Window, use the Interpolate elevation right-click command.
- Set the Scatter Set To Interpolate From to the scatter set where the unassigned scatter points have just been removed and interpolate it to this scatter set.
|
Blend Raster Resolution.
|
- Interpolating data from multiple elevation sources first requires blending the rasters involved. To do so, follow these steps:
- From the Toolbox, select Blend Raster to Edges.
- Set the Primary raster and the Secondary raster options with the rasters that are to be blended.
- Specify the distance over which the active edges of the primary raster will be blended into the secondary raster.
- Specify the name of the Output raster. This will be a separate raster created from the primary and secondary raster.
- Run the Blend Raster to Edges tool.
- Examine the newly created raster.
|
Clip rasters (optional??).
|
- Trimming rasters ensures that no part of the raster is above surveyed elevations. To do so, follow these steps:
|
- This step assumes an already-created EWN Features coverage.
1. Create feature arcs, nodes and vertices.
|
- In the Map module, create feature objects in the active coverage.
- Use the Create Feature Arc tool to create arcs in the map coverage.
- Begin creating a new arc by clicking in the Graphics Window at either arc end. If clicking on an existing feature node, vertex or arc, the new arc will snap to that object.
- Double-click or press the Enter key to terminate the arc.
- Use the Create Feature Node tool to create additional nodes alone or to split arcs.
|
2. Modify arcs.
|
- Feature arcs often need to be edited after initial creation.
3. Split arcs.
|
- An existing arc can be split by:
2. Add a node the arc.
|
- Use the Create Feature Node tool to add a node on an arc in order to split it into two arcs.
|
3. Add a new connecting arc.
|
- Use the Create Feature Arc tool to start or end a new arc on an existing arc to split the existing arc into two arcs.
|
|
4. Merge arcs.
|
- Two arcs that share an end node can be merged together.
- Select the shared node using the Select Feature Node tool.
- Right-click on the node and select the Convert to Vertex command to merge the arcs.
- If desired, the Select Feature Vertex tool can be used to select and delete the new vertex.
