Visualizing Map Data

Below is a description of how you can visualize different types of map data in 3D view.

Terrain Grid

The terrain grid is calculated from either contour maps, triangular networks, or point clouds. This terrain grid can be surface-treated with the rendering toolset. Roads and pits can also make visual interventions in this grid.

Handling Visual Noise

A common issue is visual noise from objects in the application layer. The cause depends on the data type:

  • Contour maps: Closed lines and polygons are rendered and create visual noise. These objects form surfaces that will be surface-treated
  • Triangular networks: Can also create visual noise in a similar way

Removing Visual Noise

The solution is to turn off the display of lines and polygons by using the Filter... option for the application layer.

Property Boundaries

We can visualize property boundaries in 3D using the Line Painting presentation rule. Presentation rules are set up under the Presentation... option for the application layer.

Other Applications

This presentation rule can also be useful for visualizing other types of map themes in 3D view, such as road centerlines.
