The Densify tool adds vertices to your survey items so that they better align with the underlying topography. The Densify tool only works on the selected items and appears in the TOOLS tab.

Densify works on:

  • polylines
  • boundaries

Densify works by either setting an interval (Regular) or by using an intelligent technique based on the form of the terrain (Break Points).

The Break Points method will create vertices based on elevation differences. This threshold is controlled by the elasticity value. The lower the elasticity value is set, the tighter the object will drape to the terrain. In the example below this elasticity is set to 0.25 meters. This means that no tolerance larger then 25 centimeters is allowed when adding vertices.

The Regular method will create a vertex at a user specified distance along the selected item. In the example below this distance is set to 2.00 meters.

  • The orange line is the original polyline, 
  • The green line represent the polyline after the operation. 
  • Each dot represent a vertex

Densify with break points

Use this method to create cross sections across a road or a quarry where you have significant elevation differences. 

Densify with regular interval

Use this to create surveys along a road where you need capture points at a regular distance. The above illustration is not a good example for this method but is shown for comparison purposes.

To Terrain

To Terrain is a related but different feature. To Terrain pushes vertices to the terrain but will not create additional vertices. The above illustration is not a good use case for this method but is shown for comparison purposes.


Road surveying

The Densify tool is very efficent for road surveying. In combination with the Section Lines tool it allows to quickly create cross sections along any road. This method is demonstrated in 6 steps in the video below.
