The Map tab (Figure 1) provides a Google maps style representation of nodes in the current active schematic.
...
- Map (default) - provides a Google maps style view of the current active schematic;
- Satellite - shows a satellite view of the current active schematic;
- Hybrid - provides a combination of the first two map styles; and
- Snapshot - pans zooms the entire map to show all nodes in a single screenthe map window.

Working with maps
...
- In the Map tab, choose the node you wish to add to the map (at this point, the node will appear greyed out , or disabled); and
- Click Add Marker.
If location has not been specified, the node is positioned at the centre of the map and longitude and latitude will correspond to the cross hair;(default). You can drag the node to the desired location or enter the location detail above the node list.
If location has been specified (using the Location control dialog), the node will be positioned at the specified locationthis location.

| Note: If a Gauge node has a station ID specified, it will automatically be positioned at its location after it is added to the map. |
Once a node is added to the map, it appears enabled in the nodes node list.
Removing nodes from a map
- Choose the node you wish to remove from the map; and
- Click Clear Marker.
The cross hair will appear at the node's position , but its latitude and longitude will be and it will appear greyed out (or disabled) in the node list.
Scaling
There are two types of scaling available (as shown in Figure 1):
- Zoom - zooms into or out of the map. This is synonymous to using the mouse scroll wheel; and
- Node - zooms the node into or out of the map. This is useful when there are several nodes in a small geographical area.
Additional features
- Hovering on top of a node will bring up a tooltip containing location details;

You can set geolocation coordinates and elevations for nodes and reaches using the Location Control window (using View » Location Control). While it is not essential, it is convenient to set elevations with respect to Australian Height Datum (AHD). You can enter negative numbers for components that are below sea level, such as the lower lakes of the Murray. The elevation of a component is the zero point for that component. For example, the zero point for a storage is the lowest point in the storage.

Selected marker - provides location details for the selected node.

Map datum - provides location details of the centre of the map (indicated by a red cross)
Scaling - two types available:
Zoom - zooms the maps. Synonymous to using your mouse scroll wheel.
Node - zooms the node - useful when there are several nodes in a small geographic location.
In the list of nodes, after assigning the latitude and longitude of a node, it becomes enabled.
To add a node to the map either:
Choose the node from the list and click Add Marker; or
Click the node and enter the longitudinal and latitude at the top.
This will add the node to the default location in the map. You can then click and drag the node to the desired location or enter the location details.
Once a node appears in the map, it appears enabled in the nodes list.
For a gauge node: If you choose a listed gauge, it will automatically appear in the map.
Hovering on top of a node will bring up a tooltip containing datum.
