The Map tab (Figure 1) provides a Google maps style representation of nodes in the current active schematic. For schematic scenarios, Source provides a background map image with overlaid nodes, resulting in an enhanced view of the current active scenario.

You can view different map styles using the Map toolbar (Figure 2):
- 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 the entire map to show all nodes in a single screen.

) shows nodes in a geographical setting, which can be set up using View » Maps or via the Scenario toolbar. The panel on the right allows you to manage nodes and map views. It contains the following:
- A list of nodes in the current schematic scenario;
- Tools to add and work with nodes in the map;
- Location details of a reference point (map datum), represented as a red cross; and
- A scaling feature.

Working with maps
Adding nodes to maps
Once your schematic is set up, you can add nodes to the map as follows:
- 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 map datum by 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 this 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 node list.
Removing nodes from a map
- Choose the node you wish to remove from the map; and
- Click Clear Marker.
Scaling
There are two types of scaling available (as shown in Figure 1):
- Zoom - expands or constricts the total geographic space rendered. This is synonymous to using the mouse scroll wheel; and
- Node - changes the rendered size of the node, so it can be adjusted for readability, independent of the current zoom. 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;
- To pan, right click and drag across the map;
- The panel below the map provides details at the location of the mouse pointer; and
- An approximate processing times for loading the map is also shown below the map. This value is affected by the level of zoom on the map. As the zoom level is changed, a green bar appears at the bottom, indicating that the map is in

- the process of being loaded.

You can also 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.
Once assigned,

Selected marker - provides location details for the selected node.
List of all nodes in the current scenario.
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.
