Clicking the OK button will cause your entries to be checked. If there is a problem, you may make changes; otherwise, your command will be executed.
Clicking the Cancel button will cause any changes you have just made in this dialog to be ignored and lost.
The current lowest and highest points in the current selection of loci or polygon vertices, or in the current layer's associated DTM, and the difference (range).
Unique name of the DTM. Initially the same as the name of the layer in which the data resides. If you change the data layer name, this DTM will be automatically deleted.
Name of the layer to be created (if it doesn't already exist) for 2D output. Minimum 1, maximum 20 characters.
Name of the layer to be created (if it doesn't already exist) for 3D output. Minimum 1, maximum 20 characters.
Enter the desired contour interval. Does not need to be an integer, but must be greater than zero. You can change this without recalculating the DTM.
Enter the positive integer representing the number of contour lines per index contour. For example, to get a major contour line at every fifth contour, enter 5.
Enter the datum elevation. This is used only for calculating the volume between the irregular surface represented by the DTM, and the horizontal datum plane. May be any number.
Enter the base elevation which you would want contours to be based upon. This can be used to make odd contours, such as 1,3,5,7,etc., by entering the number 1. This is usually set to 0, but may be any number.
Enter the minimum elevation for which you would want contours to be created. Originally set to the data layer's lowest 3D locus or 3D polygon vertex. For a cut & fill DTM, this would typically be less than the maximum cut (negative if there is cut).
Enter the maximum elevation for which you would want contours to be created. Originally set to the data layer's highest 3D locus or 3D polygon vertex. For a cut & fill DTM, this would typically exceed the maximum fill depth.
A popup menu in which you can choose the "from" DTM which the cut & fill DTM which you are creating should be based upon. The "to" DTM must not extend outside of the borders of this "from" DTM.
A popup menu in which you can choose the "to" DTM which the cut & fill DTM which you are creating should be based upon. This "to" DTM must not extend outside of the borders of the "from" DTM.
Name of the "from" DTM that the cut & fill DTM is based upon. This is not editable for a cut & fill DTM which already exists.
Name of the "to" DTM that the cut and fill DTM is based upon. This is not editable for a cut and fill DTM which already exists.
Check this if you would like 2D contours to be created.
Check this if you would like 3D triangular polygons to be created; this would make a visible terrain model (multi-faceted surface) when rendered. 3D polygons are not smoothable.
Check this if you would like 2D triangular polygons to be created.
Check this if you would like 3D contours to be created. 3D contours are standard 3D polygons. They are not smoothable, but they retain the elevations which they represent.
Check this if you would like contour labels to be drawn. These labels appear only with index 2D contours (such as every fifth contour), and only where the contours end at the hull (edge) of the DTM.
Check this if you would like a closed 2D polygon to be drawn to represent the hull (boundary) of the DTM.
Choose this if you would like all 2D contours that are created to be smoothed upon creation. Extra vertices are added, then the Bezier spline method is used. You could smooth later instead, by any available method; extra vertices would then not be added.
Check this if you would like objects of similar types to be grouped upon creation, such as all 2D contour lines or all 3D triangles. Contour labels would be grouped with 2D contours.
Check this if you would like breaklines (3D polygons) to be taken into account when creating the DTM, forcing linear interpolation along each leg of each polygon.
Keep this checked, unless it is a hindrance. If checked, less RAM is used, but it will take more time to recalculate. The DTM will be recreated from scratch each time you choose to calculate it.
The help view. To learn more about an item in this dialog, position the mouse over it.
Check this if you want concave sides of curves to be smoothed out automatically when the module perceives a plateau.
