This page explains the Reference View of the 3D Mapping Viewer and how to use it.

The Reference View is a 2D view on which a 2D base map from the user's choice can be overlaid with 2D vector resources and footprints and field of views of 3D resources.

Via the Basemap Selection Menu it is possible to change the 2D base map of the Reference View. It is possible to Select multiple base maps if enabled via the Viewer Settings.

How the footprints and field of views are displayed on the Reference View depends on the data type of the available resources.

Mobile Mapping and Planar Photo Positions

• Blue dots: Represent the photo positions or recording locations. These are visible up to a map scale of 1/1500.
  
• Blue pie-slices: Heading and field of view of a Mobile Mapping View. The number on the pie slice corresponds to the number of the view.

Photo positions can be turned on/off from the Resources Sidebar

Oblique Footprints

• Blue quadrangle: the border of the footprint of the active photo.
• Green cross: Center of Oblique View.
• Red cross: Location of the cursor on Oblique View.

Footprints can be turned on/off from the Resources sidebar.

Vector overlays

Vector layers are by default not displayed in the Reference View. This can be changed via the Viewer Settings.

How vector overlays are displayed is dependent of the legend of the vector layer. This can be set in the Resources sidebar. Note that a vector dataset may not be visible due to scale limit limitations.

It provides the possibility to change the active base map in the workspace.

Basemaps are displayed on the Reference View and optionally in 3D Views if enabled via the Viewer Settings.
