• Access to 3D Scene is via the VVG portal. The option will be greyed out until you are zoomed in to a minimum of 1:108K (as shown in bottom left corner of portal).
• Zoom into the area you would like to see in 3D and click on '3D Scene' which is located in the top right corner of the map under the Google layers (Figure 1).
• You will be redirected to the 3D Scene webpage in a new tab or window.

• These tools (Figure 2) are found in the top right hand corner:
  • Toggle Perspective - Click on this to change the perspective (two options). 
  • Toggle axis - Click on this to remove the box around the 3D Scene and its depth and coordinate markers (Eastings and Northings).
  • Reset View - click to go back to the original view that first loaded, including removing any slice you have made.
  • Top, bottom, North, South, East and West view - clicking on these shows the face of that view
  • Slice front and back view - When you use the slice tool, this give you a section view from the front (where the slice was taken) or the back (the edge).

• When the scene loads, there is an axis (Figure 3) in the top right corner that shows:
  • Blue cone - upwards direction
  • Green cone (N) - North direction
  • Red cone (E) - East direction
• This axis can be moved by clicking the mouse over it and dragging to move it to your position. 

• To create a cross section you will need to use the tools under 'Cross Section Tools' on the right hand side of the 3D scene page (Figure 4)
• Turn the slice mode on by clicking which covers the icon with a green square  when on. A red rectangle will also appear in the 3D scene (Figure 5).
• The red rectangle is where the slice cuts through (Figure 6) and clicking on that will slide the slice tool backwards and forwards. The long pipe with cones on the end and a sphere in the middle is used to change the angle of the slice.
• It is recommended to cut the slice  straight away so you can make full use of the toggle slice (you can re-cut the slice multiple times). Alternatively rotate the 3D scene to a side view to see the red pointer with cones at each end as shown in Figure 6.
• After slicing there will be a line with a cone at both ends (the layers may be covering the other end as in fig x) and a sphere in the middle.
• To slide the slice tool along the 3D area, click the red edged rectangle and drag to the desired position.
• To change the angle of the slice, click one of the two red cones or the line between them and hold mouse down to move to the angle you would like. This spins around 360º (Figure 6).
• Keep in mind, the surface layers will disappear on the side that has the cone pointing outwards. The bore group layer will remain on the layers that have been cut away if ticked. To learn how to remove bores from view go here.
• Click  again. You can re-cut the slice many times over.
• To reset the slicer to the original angle and position and undo any cut that has been made click on .

• The vertical exaggeration tool (Figure 7) increases the vertical scale to allow you to see vertical features more clearly in the landscape. 
• The tool is featured as a sliding scale on the right side of the 3D Scene page
• The default is set to 15x (vertical scale 15 times greater than the horizontal scale) and by clicking on the scale slider you can vary it between 1x and 100x.

• Double mouse click a bore at the site marker (pentagonal cone) and the marker will have a light grey cover shown over it, the bore ID will be shown and if depth information is available it will be shown as per Figure 9. The red pipeline will change to a dashed line.

• The surface and aquifer layers are found by clicking the  next to the 'Surface' folder in the top left hand corner of the 3D scene page (Figure 12).
• To remove a layer from view, click the ticked box  next to the desired layer and it will untick .
• To change other settings with the layers, click on the name of the layer you wish to change and a set of options will come up below (Figure 13).

• Clipped - untick this box to show the whole layer even when a slice is cut.
• Slice visibility - this will show the layer edge at the sliced location even when the layer is hidden.
• Overlay - This is a drop down box that shows either 'Solid colour' or 'Elevation map' for the aquifer layers and also includes 'Aerial (Landsat7)', 'Aerial Photo' and '50k geology' for the Ground surface.
• Overlay legend - This displays a legend for the selected overlay if there is one (Elevation map?).
• Contour visibility - Tick this box to show contour lines for the layer (Figure 14).

• Contour labels - Tick this box to show the height of the contours in metres. The 'Contour visibility' box must also be ticked for this to be visible.
• Contour step (m) - This is a sliding scale to change the increments in which the contour lines will be shown, varying from 1 - 100m. Again, the 'Contour visibility' box must be ticked to view the steps.
• Opacity (%) - This changes the ability to 'see through' the layers. The default is 100% which is a solid layer, you can go down to 0%, where the layer would not be visible anymore. Example shown in Figure 15, with the surface shown at 42% opacity. You can see the pipelines for the bores.

• Click on  next to the 'Surface' folder in the top left hand corner of the 3D scene view.
• This will drop down the aquifer and surface layers.
• Click on the 'Ground surface' layer to bring up the options below.
• Click on the 'Overlay' drop down box and select 'Aerial photo'.
• If the aerial photo looks patchy, it is due to the aquifer layers shown higher. Hide these, or decrease their opacity.

• Click on  next to the 'Surface' folder in the top left hand corner of the 3D scene view.
• This will show the aquifer and surface layers.
• Click on the 'Ground surface' layer to bring up the options (Figure 18).
• Click on the 'Overlay' drop down box and select 'Victoria Geology 50K/'. This will drape the geology over the surface as seen in Figure 19.
• If the geology looks patchy, it is due to the aquifer layers shown higher. Untick these, or increase their opacity.
