Data aggregation

Aggregation is a way of transforming a dataset into one resulting value (sum of values, average value, and others). To enrich information about the area displayed on the map, you can aggregate data from another layer.

Aggregation is available for layers with areal objects: Proximity zones and Polygons.

Example scenario

Calculate the average rating of competitors or the amount of living population within a 5 minute proximity zone for a new organization branch.

Creating aggregation

1. Create a layer with data that you want to aggregate.

   For example, if you want to aggregate data about residents, create a layer from the Population category for the required territory.

2. Create a layer with areal objects: Proximity zones or Polygon visualization method. The layers must be within the same dashboard.

3. Go to the Dashboards tab.

4. Select the required dashboard.

5. Click icon.

6. Select the required layer with areal objects.

7. Click Aggregate data.

8. Set aggregation parameters:

   
   • New layer name: enter the name of the resulting layer.
   • Data layer: select a layer with the data you want to aggregate.
   • Attributes: specify the data type for aggregation. Dataset depends on the selected layer.
   • Aggregation method: select a method of transforming data.

   To add aggregation of other data or another method, click Add attribute.

   Note

   You can add not more than 20 attributes for one aggregation layer.

9. Click Create.

A new layer with the Polygon visualization method is created and automatically added to the dashboard. If necessary, you can specify visualization parameters for the layer.

To see the aggregated data in a tooltip, hover over any polygon or proximity zone:
