Aggregated Properties

Dimensional queries might return multiple versions of the same feature.

If we take a vehicle for example, the Time Range widget might generate a request for all vehicles positions within the specified period. Since a vehicle might have travelled, the WFS service will return multiple versions of the same feature (same identifier).

The feature aggregation will combine the response into a single feature.

• Numerical properties will be averaged.
• Shapes will be combined.
• Points become trajectories (polylines).
• Text properties become lists.
