Examine Model Elevation

(This functionality is available with the Modelling module)
(Not available in LISCAD Lite)

Examines the elevation and characteristics of an existing point or cursor position with respect to the current model.
Characteristics include an elevation interpolated from the current model, and the direction of dip, and grade of dip of the model at the point or cursor position. Please note that the dip direction is always a Plane Bearing, Azimuths are not be displayed. Note that slopes of 1:100,000 or less are considered flat, and no aspect will be displayed.

On selecting the Elevation/Examine command from the Terrain Modelling task, the Examine Model Elevation dialog box is displayed.

You may operate this dialog box in either 'Dynamic' or 'Static' modes. In dynamic mode the values displayed will be updated to reflect the current position of the mouse. In static mode a point must be selected, or a mouse position nominated by pressing the left mouse button.

You may use this dialog box to select a point to be examined for its interpolated model elevation. Snap to an existing point in the data base or alternatively click at any position within the model area to return an interpolated model elevation. Note that the data base must have previously been triangulated and a model displayed for an interpolated model elevation to be returned.

Note that the interpolated model elevation for a point is not the elevation attribute of the point, unless that point was used in the formation of the model triangles, or unless the Examine/Interpolate command has been used to make the interpolated elevation the actual elevation attribute of the point.
