For schematic scenarios, Source provides a background map image with overlaid nodes, resulting in an enhanced view of the current active scenario. The Map tab (Figure 1) provides a Google maps style representation of nodes in the current active schematic. shows nodes in a geographical setting, which can be set up using View » Maps or via the Scenario toolbar.

The cross hair will appear at the node's position 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 expands or out of the mapconstricts the total geographic space rendered. This is synonymous to using the mouse scroll wheel; and
- Node - zooms the node into or out of the mapchanges 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.
...
- Hovering on top of a node will bring up a tooltip containing location details;
- 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 is in the process of being loaded.

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.
