Maps

The Map tab (Figure 1) provides a Google maps style representation of nodes in the current active schematic.

Note: This feature is currently only operational for an active Internet connection. Links and geographic projections are not displayed on the map.

Figure 1. Maps

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 - zooms the entire map to show all nodes in the map window.

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 centre of the map (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.

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 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;
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 number of nodes on the map, along with the amount of detail.

Location control

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.
