Manage surfaces

SURFACES&VOLUME

• The list of surfaces available in the project is opened selecting Surfaces from the Volumes page.

• The table reports the list of all the surfaces present in the archive.

  

• For every surface are reported the minimum and maximum elevation, the 2D surface and the 3D surface.

Surface editing

• To edit the shape of the triangles composing a surface select the corresponding line in the list of surfaces and press the View button.

• The commands of the graphic viewer allow to edit the surface.

  

  • Settings: allows you to modify the surface visualization settings and display parameters. Opens the Surface properties page.

  • New: creates a new triangle. Select the three points that will define the triangle.

  • Swap: changes the common edge between two adjacent triangles, modifying the triangulation and the orientation of the triangle faces in that area.

  • Delete: allows you to select and remove one or more triangles from the surface.

Surface properties

• To edit the visualization parameters of a surface select the corresponding line in the list of the surfaces and press the Modify button.

  

  • Name: name assigned to the surface.

  • Style: display style used to represent the surface. Available options are:

    • Wireframe: displays the edges of the triangles that compose the surface triangulation.

    • Shaded: displays the triangular faces with shading based on the direction of light exposure, providing a more realistic representation of the terrain.

  • Color: defines how the surface is colored. Available options are:

    • Original: uses the color of the layer containing the surface triangles.

    • By Elevation: colors the surface according to elevation values. The color scale ranges from green (lower elevations), through yellow, to red (higher elevations).

    • Surface: uses a custom color specified in the Surface Color field.

  • Surface Color: custom color used to display the surface when the Surface color option is selected.

• Press Next to create contour lines.

  

  • Contour Lines: enables the display of contour lines generated from the surface.

  • Contour Step: specifies the elevation interval used to generate the contour lines.

  • Contour Color: defines the color used to display the contour lines.

Delete a surface

• To delete a surface select the corresponding line in the list of the surfaces and press the Delete button.
