The VVG portal contains extensive information on nearly 300,000 bores across the state of Victoria. This dynamic map is an interactive spatial interface to the underlying information. The instructions are a rough guide on how to use the map. Please be aware that the system is regularly being refined and updated and these instructions will be updated from time to time.
Note: If you have an Apple Mac, find out how to navigate the portal here.
Quick guide to get started
There are several ways to navigate around using the map interface, your pointer device (mouse) and your keyboard.
- Double-click on the map to zoom in
- Click and drag to pan around the map
- If your mouse has a scroll-wheel, you can use this to zoom in and out.
- You can also use the 'zoom bar' in the top right hand corner of the map to zoom and pan.
The layer switcher allows you to manipulate the data which is displayed on the map. It is broken into two separate sections, Base maps and Layers (or overlays). Simply click on the various layers to toggle them on or off. Some layers take longer to load than others and some are slower to load at the full map extent. Underneath the map in the status bar you will see a loading animation which will be activated when the map is loading.
- Turn layers off to speed up navigation and zooming, the more layers you have turned on the longer you may have to wait each time you zoom or pan.
- Turning on a layer may trigger other parts of the interface to change. The Info/Legend/Tools areas will update to reflect the layers you have switched on or off.
Querying the map for information
As the amount of data layers available on VVG has increased, the querying options have become more complicated. We hope to simplify this in the near future.
To query the map just click on the point of the map you are interested in, information related to that point will return information in a small popup window. The type of information returned is dependant on the selected 'query mode'.
The 'query mode' select box is located under the layer switcher on the right-hand-side of the map. This option allows you to change between different query groupings. The default query mode is 'Bores' which will query for bores within a 300 metre radius of a single mouse click on the map. Other query modes are listed below.
- Bores: This mode will query the DEPI (GEDIS), DEPI (Water Measurement Information System) and FedUni Bores within a 300 metre radius of the selected point.
- SRW Aquifers: This mode will query the Southern Rural Water surfaces for values at that exact pixel location.
- DSE Statewide Aquifers: This mode will query the DSE aquifer surfaces for their values at that exact pixel location.
- GSV Geology: This performs a remote query to the Geological Survey of Victoria's seamless geology layer.
- FFSR Bores: Currently this bores layer need to be queried separately to the other bore layers. You must also have this layer turned on in the layer switcher for the querying to work. It is also different from the other 'bores' query mode in that you must select the point feature directly (it is not a radius based search).
