Statistics Tab (Surface Properties Dialog Box)

Use this tab to display surface statistics that are based on the current state of the surface.

Displays the general statistics for a surface.

Revision Number: Displays the revision number of the surface.
Number of Points: Displays the number of vertex points in the surface.
Minimum X Coordinate: Displays the minimum X coordinate for the surface area.
Minimum Y Coordinate: Displays the minimum Y coordinate for the surface area.
Maximum X Coordinate: Displays the maximum X coordinate for the surface area.
Maximum Y Coordinate: Displays the maximum Y coordinate for the surface area.
Minimum Level: Displays the minimum level value found in the surface.
Maximum Level: Displays the maximum level value found in the surface.
Mean Level: Displays the mean or average level of all the points on the surface.

2D Surface Area: Displays the two-dimensional area of the surface.
3D Surface Area: Displays the three-dimensional area of the surface.
Minimum Gradient/Slope: Displays the minimum gradient or slope found on the surface. Expressed in the units specified in the Edit Feature Settings - Surface Dialog Box.
Maximum Gradient/Slope: Displays the maximum gradient or slope found on the surface. Expressed in the units specified in the Edit Feature Settings - Surface Dialog Box.
Mean Gradient/Slope: The mean or average gradient or slope for the surface. Expressed in the units specified in the Edit Feature Settings - Surface Dialog Box.

Note: The following properties are displayed for Triangulation surfaces.

Number Of Triangles: Displays the number of triangles found in the surface.
Maximum Triangle Area: Displays the area of the largest triangle contained in the surface.
Minimum Triangle Area: Displays the area of the smallest triangle contained in the surface.

Note: The following properties are displayed for grid surfaces.

X Spacing: Displays the distance between the grid lines in the X direction.
Y Spacing: Displays the distance between the grid lines in the Y direction.
Orientation: Displays the orientation of the grid (in degrees). The angle is clockwise (+), or counterclockwise (-) from the North-South meridian.

Note: The following properties are displayed for volume surfaces.

Base Surface: Displays the name of the base surface from which the volume surface is generated.
Comparison Surface: Displays the name of the comparison surface from which the volume surface is generated.
Cut volume (unadjusted): Displays the total cut volume for the surface, without a cut factor applied.
Fill volume (unadjusted): The total fill volume for the surface, without a fill factor applied.
Net volume (unadjusted): The difference between the cut and fill volumes.
