Overview

Draw object clustering is used to

  • Make complex situations easier to comprehend
  • Increase performance by reducing information in map

Clustering allows a very large amount of objects to be displayed, without decoding the object data.

Currently, two clustering modes are available:

  • Grid clustering, groups dense clusters of point and area objects and display these as circular or bounded areas
  • Time fade clustering/filter will only display objects that are available within a time window. Fade times can be set globally or per object.
