Combine Triangulated Networks¶

Use this dialog to calculate intersections between triangulated networks.

Where can I find the dialog?¶

On the toolbox, select the Combine Triangulated Networks... icon.

Using the dialog¶

The result can be:

Volume
Area
Combined surface

When you define a calculation, the procedure is the same, but the available options vary depending on the calculation method you choose.

Below is the procedure for Volume.

Procedure

Select Calculate Quantities from Triangulated Network... in the toolbox.
Select the calculation method Volume.
Optionally, select a restriction layer (triangulated network or polygon) to limit the calculation.
Select the relevant triangulated network for From layer and click Add >>. You can select layers either from the triangulated network list or by choosing Locate... and selecting one or more layers directly in the model. Check Highest or Lowest if you have multiple from-layers.
Select the relevant triangulated network for To layer and click Add >>. You can select layers either from the triangulated network list or by choosing Locate... and selecting one or more layers directly in the model. Check Highest or Lowest if you have multiple to-layers.
Select which application layer the result should be placed on.
Click OK to perform the calculation.

Tip

Try out the different options in the function. If the result is not as expected, simply delete it and try again.

Examples¶

Volume¶

Intersection volume calculated from two triangulated networks that intersect each other

After calculation, you get an exact volume triangulated network

Combined Surface¶

In this example, we have three triangulated networks with different base elevations (marked with a red polygon), and all base surfaces have side surfaces that intersect with the terrain.

After calculation, you get a new combined surface for the lowest level.

Note

Note that only the result is placed on the result application layer. The calculation setup itself is not saved.
