1. Review elevation data for errors.
1. Use the Dataset Info dialog.
  1. Find the "Z", "elevation" or "depth" datasets on the geometric object (mesh, TIN, grid, raster) that is being reviewed
  2. Right-click on elevation data and select Info.
  3. Review information in the Dataset Info dialog to see that the range of values are as expected.
2. Use contour display options.
  1. Turn off Points and Triangles, then turn on Contours in the Scatter tab of the Display Options dialog.
  2. Set contour options in the Contours tab. The "Color Fill" option is recommended for this.
  3. Look for inconsistent points (points with values much higher/lower than their neighbors or regions where no data points exist).
  4. Verify that the region being modeled is covered by the elevation/depth data and there are no holes.
3. Rotate the elevation data.
  1. Use the Rotate Rotate Tool.svg tool to examine the elevation data from different angles.
2. Remove erroneous points and triangles.
After reviewing the imported data, points or triangles covering regions where there are no data points should be deleted. This could include outlier points or thin triangles.
1. Use the Scatter Options dialog.
  1. Open the Scatter Options dialog.
  2. Select or delete duplicate points.
  3. Select or delete long triangles.
  4. Select thin triangles.
  5. Use a triangulation optimization option.
2. Manually remove points.
  1. Use Select Scatter Point Select Point Tool.svg tool to select erroneous points in the scatter set.
  2. Review and edit point data in the Edit Window.
  3. Delete erroneous points.
3. Add breaklines.
  1. Select the Create Breakline SMS Create Nodestring Tool.svg tool.
  2. Click along points of a common elevation, such as at a bank toe or levee crest, to connect these points in the surface.
  3. Use the Backspace key to back up if an erroneous selection is made.
  4. Double-click or press Enter key to complete the breakline.
4. Merge elevation datasets.
  1. Select the Scatter | Merge Sets command.
  2. Use the Merge Scatter Sets dialog to select elevation data to be merged.
