Run a Surface Information Report

Run a Surface Information Report to see measurements and limits, as well as the number of triangles, vertices, breaklines and drapelines for any surface (or isochore) in your project. In addition, you can choose to include information on the surface's area sorted by elevation/depth range and by slope range.

Tip: Run this report on isochores to see the area in which cut and fill are needed (shown as negative and positive values in the Area by Depth table).

Prerequisites:

surface of any type

To access the command:

Select Reports > Report Options in the Quick Access Toolbar and then double-click Surface Information Report in the list.
The Surface Information Report command pane displays.

To generate a Surface Information Report:

Select the surface (or isochore) that you want to generate a report for in the Surface list.
Note: You cannot run a Surface Information Report on a tunnel surface because it represents only interior walls of a tunnel, not topography.
To report on the surface's area by elevation range, check the Include table box in the Area by Elevation group.
- To redefine the surface's elevation ranges used to report areas by elevation, click Define Elevation Ranges. The Edit Color Mapping dialog displays (see the help topic called Edit Color Mapping for a Surface or Difference Model).
  Note: If you choose to report on a surface, the label for this group and corresponding report table will show Area by Elevation. If you report on an isochore, the label and report table will show Area by Depth.
  Note: In the report, the elevation ranges are defined by the color mapping (number of color bands) on the surface.
To report on the surface's area by slope range, check the box for Include table in the Area by Slope group.
1. To redefine the slope percentage ranges used to report areas by slope, click Define Slope Ranges.
2. Review the Defined range limits for the surface's slopes in the dialog.
3. To define an additional range, type its upper limit in the New slope limit (%) box and click Add.
4. Select any unneeded range limit in the list of slope ranges and click Delete.
5. Click OK when you are done.
Click OK. The report displays in the Report View.

Options:

Click the Report Options icon to open the Report Options command, where you can specify header, footer, and other settings for the report.
Area by elevation/depth - Select this to show the surface's planimetric area (actual area, if sloping, is not reported) separated into ranges of elevation (as specified in the Edit Color Mapping dialog). For the report's calculations, each surface triangle is divided so that the triangle edges reform at the specified elevation limits. The areas of triangles whose elevation fall within the same range are combined and reported in the table.
Area by slope - Select this to show the surface's area separated into ranges of slope (as specified in the Define Slope Ranges dialog). The area in each range is shown as both planimetric and actual area. Each surface triangle, as a plane, has a slope. The areas of triangles whose slopes fall within the same range are combined and reported in the table. If, for example, the range limits are 0, 5, 10, and 20, the report will group and report surface triangles whose slopes (in %) are from 0 - <5, then 5 - <10, 10 - <20, and 20 - ¥.
Define slope ranges - Click this to redefine the slope percentage ranges used to report areas by slope. See the lettered steps above.
