Template:SMS Review Elevation Data Workflow

1. Use the Dataset Info dialog.
Find the "Z", "elevation" or "depth" datasets on the geometric object (mesh, TIN, grid, raster) that is being reviewed Right-click on elevation data and select Info. Review information in the Dataset Info dialog to see that the range of values are as expected.

2. Use contour display options.

Turn off Points and Triangles, then turn on Contours in the Scatter tab of the Display Options dialog. Set contour options in the Contours tab. The "Color Fill" option is recommended for this. Look for inconsistent points (points with values much higher/lower than their neighbors or regions where no data points exist). Verify that the region being modeled is covered by the elevation/depth data and there are no holes.

3. Rotate the elevation data.
Use the Rotate tool to examine the elevation data from different angles.
