Aggregated Properties

Dimensional queries may return multiple versions of the same feature.

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

The feature aggregation combines the response into a single feature.

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