Clustering

Clustering on a map

The map-clustering groups together a set of features (most of the time routes) on a map and shows only one symbol or square for the whole set.

There are two main reasons why we do this:

• Otherwiste your map view gets cluttered/overloaded
• If we would send all the data available, your browser would flip or it would take a very long time before you get all the results in

Here is an example where we use it on the Route Search:

In this case, the area of the map shows a large number of routes, but only a few are shown on the map and on the list.

You can see more in the following way

• Click on the (+)-symbol at the top of the list (repeat)
• Zoom in on an area

The cluster is represented by a grey-square. Only one route is shown per cluster as default. In this case, it is the route with the best score.

Clustering is used on many maps such as:

• the Route Search.
