Navigate around the map (pan)

Tip - Turn layers off to speed up navigation. The more layers you have turned on, the longer it will take for everything to load each time you zoom or pan.

Base maps (satellite view)

  • The base maps layers are located in the top right corner of the map (Figure 2).
  • The layer displayed on the map will be shown in bold.
  • Left-click mouse over a different one to change the view e.g. Google Hybrid for satellite view.
Figure 2


  • Overlay layers display information such as bore sites, elevation, salinity, geology and other sites of interest.
  • To select a layer, simply tick the box next to the overlay name (Figure 3).
  • Multiple layers can be chosen, however this may slow down your ability to navigate the map as each layer reloads.
  • Layers correspond to the query mode. See Query the map for information for further details.

Aquifer Layers

  • The Advanced aquifer tools layers come from the Victorian Aquifer Framework.
  • Click the  button to choose to display individual aquifer layers by thickness and elevation (Figure 4).
  • To expand an aquifer/aquitard folder click on the corresponding folder  (Figure 4). This will show you the different options you can tick .
  • Layers correspond to the DEPI Statewide aquifers query mode. See DEPI Statewide aquifers for details on querying. This will also show you how to generate all of the the aquifer layers from a point on the map.

Figure 4

Note: The layers in Advanced aquifer tools can be slow to load, and will still process even if you untick a layer. If the layers are still loading, you will see a pink bar  in the lower right-hand side of the map.

  • Click on the  button located in the top right tabs above the map.
  • Under 'Active Layer Options' (Figure 5) the layers you have selected to appear on the map will be listed.
  • The layers are in order from the top of the list to the bottom as they are on the map front to back.
  • To move a layer, left-click mouse over layer and drag up or down to desired position.
