====== Scope tab ======

The **Scope** tab allows you to define the scope of the
**Time-Location view**.

This is where you determine **what will be visible in the view**,
from a temporal, geographical, and organisational perspective.

Three main elements make up this interface.

-----

===== 1. Spatio-temporal scope =====

This area allows you to define the **temporal and geographical limits**
of the view.

Here you configure:

  * the **start date**
  * the **finish date**
  * the **starting chainage**
  * the **ending chainage**

These parameters define the **observation window of the schedule**.

Only activities included within this temporal and
geographical range will be visible in the view.

The **Reverse Date** and **Reverse Pk** buttons allow
the orientation of the corresponding axis to be reversed.

-----

===== 2. Project scope =====

This area allows you to select **which project elements are displayed**
in the view.

It is possible to enable or disable:

  * **projects**
  * **subprojects**
  * **planning levels**

This makes it possible, for example, to create views dedicated to:

  * a specific subproject
  * a work package
  * a specific level of detail

-----

===== 3. Geographical scope =====

This section allows you to define **which geographical zones are visible**
in the view.

Zones generally correspond to project elements such as:

  * structures
  * sections
  * junctions
  * work areas

By enabling or disabling certain zones, it becomes possible
to **restrict the schedule display to a specific part of the project**.

This is particularly useful for creating views dedicated
to a specific section of the alignment.
