Topography-specific Functions

Preliminary Note

In this chapter, specific features (with examples) are described applicable when generating and editing digital terrain models in CadnaA.

In each of the following chapters the range of application and the effects of each feature are described. The presentation focuses on the software-related functions and procedures, also addressing possible user criteria when applying a feature or function. Please consider that just the mere existence of a feature or function does not mean, however, that it may be appropriate to be applied in a particular case.

The decision, which feature or function may apply in a particular case cannot be taken by the software itself, but remains in the responsibility of the user.

Topography-specific Functions

The subsequent chapters cover the following program functions:

• see Fit Objects to DTM
• see Fit DTM to Object
• see Generate Terrain Contours from Height Points
• see Generate a Grid of Height Points from Terrain Contours

Further Features for processing Terrain Data

In addition, further software features are available which can be used when importing terrain data or in order to modify existing an terrain model. In each particular case the user decides whether a specific software feature is useful and appropriate.

• see Simplify Geometry in the manual „Introduction to CadnaA“
• see Close Polygons
• see Thin out Height Points
