# Metrics - Network

This module allows you to compute hedge network metrics, such as the network distance to the closest forest.

The hedge network is constructed from scratch the first time you run an algorithm from this module.  
The network characteristics are then stored in two fields in the line vector layer:

- `network_id`: Unique identifier of the network. Hedges sharing the same ID belong to the same network.
- `n_threshold`: Distance threshold used to consider hedges without a physical connection as connected.

For each algorithm, you can choose to build the network using the stored values or ignore them and rebuild the network using a new spatial threshold. In this case, the corresponding fields in the line vector layer are updated accordingly.
