Cluster

The Cluster display method will be useful when there are too many points on the map. In this case, it is more convenient to work with their groups — clusters. The size and color of the cluster depend on the points counts covered by it.

When you zoom in on the map, large clusters first break up into smaller ones, and then into separate points. When you zoom out on the map, small clusters are grouped into larger ones.

Cluster

To choose a display method:

  1. Go to the Layers tab.
  2. Select the layer group.
  3. Select the necessary layer.
  4. Select the Cluster display method on the General settings tab.
  5. Set the remaining filter parameters if necessary.

The data will be visualized on the map.

For the Cluster display method, the following parameters are available:

  • Radius:

    • Cluster size: the value in px from 1 to 250, based on which a point is included in the cluster. If there is a point at the specified distance from the cluster center, it will be included in the cluster.
    • Radius range: the radius of the element in px from 1 to 100.
  • Color: the color scale of the data display.

    • Color basis: the parameter based on which the elements on the map will be colored according to the Color scale. The available values depend on the selected data category.
    • Color scale: the set of prepared color samples.
    • Invert: select to invert the selected color scale.
    • Steps: gradation of the color scale from 1 to 10.
    • Legend: symbols for color and prepared data.
    • Color aggregation type: the color aggregation method — Sum or Mean.
    • Type of scale: Linear — displays of values of the same order; Logarithmic — displays of a wide range of values, when the values may differ by several orders of magnitude.
    • Opacity: setting the opacity of the elements on the map.
  • Outline: selecting the color and width of the line in px for outline elements on the map.
