What is a network in Alloy?

A network is a special layer that provides a framework with which you can reference assets. For example a network can represent all the roads with an area of responsibility. You can select a network to view it on the map and use it to reference other spatial data, for example all street lighting can be referenced to a network.

With Alloy, you can switch between different networks and asset types.

You can view all available networks by selecting the button in the right panel. The networks are listed and a toggle switch indicates whether they are active and displayed on the the map.

Note

A network layer requires at least one style in order to display the network items on the layer, see Adding layer styles.

Active network and data referencing

All spatial data you can select in Alloy is referenced against the selected network. Any reports you select are run for the selected network by default. Make sure the network type you have selected matches the asset type you want to work with (e.g. Gazetteer for Street Works, or a centreline network for carriageways).

Since Alloy lets you load multiple networks, you can include different networks for different user groups.

Networks and zoom levels

When the map is zoomed out, the active network appears as solid lines that you cannot select.

As you zoom in, you can select sections from the active network. When you select an item or carriageway section, its details show in the right panel.

You can also view a graph of each component the section is made of. See Viewing items.
