Grid aggregation

Grid aggregation

edit

The Grid aggregation source uses GeoTile grid aggregation to group your documents into grids. You can calculate metrics for each gridded cell.

Symbolize grid aggregation metrics as:

Clusters
Creates a vector layer with a cluster symbol for each gridded cell. The cluster location is the weighted centroid for all geo-points in the gridded cell.
Grid rectangles
Creates a vector layer with a bounding box polygon for each gridded cell.
Heat map
Creates a heat map layer that clusters the weighted centroids for each gridded cell.

To enable grid aggregation:

  1. Click Add layer, then select the Grid aggregation source.

To enable a blended layer that dynamically shows clusters or documents:

  1. Click Add layer, then select the Documents source.
  2. Configure Index pattern and the Geospatial field. To enable clustering, the Geospatial field must be set to a field mapped as geo_point.
  3. In Scaling, select Show clusters when results exceed 10000.
