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.
