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 Properties.
  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 on Contours in the Display Options dialog and set contour options. The "Color Fill" option is recommended for this.
  2. Look for inconsistent points (points with values much higher/lower than their neighbors or regions where no data points exist).
  3. Verify that the region being modeled is covered by the elevation/depth data and there are no holes.
