OptionallayersAn array of elevationLayer objects defining the elevation of the ground in the web scene.
OptionalnavigationDetermines whether the camera is constrained to navigate only above, or also under the ground surface.
The type of constraint.
OptionalsurfaceDefines the color of the ground surface, displayed underneath the basemap. If no color, the default grid is shown.
OptionaltransparencyThe transparency of the ground surface. It is used for seeing through the ground, therefore this property also changes the transparency of the basemap. Draped operational layers are not affected by this property. The value has to lie between 100 (full transparency) and 0 (full opacity).
