Model Edits (Terrain Filtering)

In this article, we will discuss and give examples on how to filter out noisy areas. Filtering out noisy areas will have an effect on the contour lines display as well as on measurements such as volume calculations. As an example let’s look at the triangular area in the figure below where part of it has large rocks and the contour lines are very noisy.

To filter out the noisy area select the Model Edit tab from the left and click on “+ Add filtered area”.

Draw a polygon by clicking its corner point and closing it with a double click. This will show the marked area and it will show you some measurements of the area. At this point you may preview the result or simply save it. Previewing it will show you the new contour lines for that area as shown on the right side below.

Saving it will list it on the left panel as shown below as shown below and you will now have the option to turn that filter on or off as needed.

The two figures below show an example of volume calculation with and without the filters for the same area.
