Feature relationships

Features in Siter can be linked to other features through relationships. A relationship overrides the analysis criteria Siter would apply between two facilities by default — for example, forcing a barricaded type code on a PES-ES pair or excluding a pair from analysis altogether.

Prerequisites​

  • You must have at least two features in the project to create relationships
  • You must have the Project Edit Permission or higher

Relationships vs. Spatial Analysis​

The feature dashboard exposes two tabs that both deal with how features interact:

  • The Relationships tab lists user-defined and auto-generated relationship overrides for this feature. It is empty by default. Rows here change which criteria type code Siter uses between two facilities.
  • The Spatial Analysis tab lists every nearby feature the most recent analysis found, with the calculated distance and the criteria type code in effect. It is read-only and re-populated whenever you run analysis.

Use Relationships to change how a pair is treated. Use Spatial Analysis to see what the engine actually did.

How to view relationships​

  1. Select a feature to open its dashboard

  2. Click the Relationships tab

    Relationships tab on the AGM 1 feature dashboard with the Overridden only filter toggle

  3. If no relationships have been defined for this feature, the table shows "No relationships defined"

  4. Toggle Overridden only to filter the table to rows that override the criteria default, hiding the auto-generated rows from relationship groups

How to add a relationship​

  1. Open the feature's Relationships tab
  2. Click the add icon in the dashboard header
  3. Select the feature you want to link to
  4. Define the relationship type — typically a criteria type code (e.g., B for Barricaded) or NA to exclude the pair from analysis
  5. Click Save

Relationships are bidirectional — adding a row to Feature A's Relationships tab adds the same row to Feature B.

tip

For projects with many facilities, prefer the Relationship Group Editor to author a full Group × Group × Criteria matrix and bulk-generate relationships, rather than editing one pair at a time. To review or edit every pair in the project at once, use the All relationships dashboard.
