Description

dtm-create provides the facility to generate a DTM object from a series of disparate strings. The breadth of functionality offered by this command can be summarized as such:

• Choice of full object input and/or individual strings and points

• Ability to create dtm attributes from input data attributes

• Optional creation of spur strings to avoid plateaus on ridges and valleys

• Optional automatic best-fit DTM plane in addition to world and view plane options

• Automatic nesting of boundary limit strings

How to Use

1. Run the command.

2. The Make DTM wizard is displayed. Fill in the required settings and click Next to proceed to next stage of the wizard.

3. Select the points and strings to be used to create the digital terrain model. Click Next.

4. Select boundary strings (if required) from the displayed list of objects. Click Next.

5. A new DTM object is created,based on the selected strings, and honoring the specified boundary strings. Click Finish.

Notes on Using Boundary Strings

Care should be exercised when creating a DTM using view coordinates rather than world (XY) coordinates. For example, if the plan view is in use, but the view direction is set to a significantly different orientation, unexpected results can occur. For this reason, if you have configured a view direction with this type of deviation from the world plane, particular care should be taken in the definition of inner/outer limit strings.
