Using the Qgis MarkerCluster plugin to create cluster maps

This post will demonstrate how to use the Qgis MarkerCluster plugin to create cluster maps.

1. First Install the plugin. Go to ‘Plugins’ on the main menu tab – Manage and install Plugins



2. The Plugins window will open. Click on ‘All’ and then search for the plugin.



3. In case your search comes up blank, then go to ‘Settings’ and check the box the

has the option ‘Show also experimental plugins’.

(cursor pointer position on the screenshot below)


Then go back and repeat the process at number 2.

4. Once the plugin is installed, click on the ‘Marker Cluster Plugin’ icon button

(cursor pointer position on the screenshot below).



5.  The Qgis MarkerCluster Plugin interface will open  under the Layer window. See the interface red boxed on the screenshot.



6. To form a clusters from the point features, click on ‘Setup First Cluster’ and input

a cluster distance of choice.



7. In red box (1), a Cluster shape is generated as seen on the map canvas. In red box (2),

user input a Cluster Distance (uses this distance to measure which points are close

enough to each other to group or cluster).

We use 0.008DD in the demo. If the user edits this Cluster Distance, the clustered groupings will either increase or decrease in number.

Note also that a new layer- Cluster- is added to the map layers.



8. Next we proceed to change the default style of the Cluster layer. Right Click on the

layer and scroll the list and choose ‘Properties’.



9.  Click ‘Style’ to open the Style page. 1. Change the Fill colour 2. Change the color of the border line.3. Adjust the size to make the cluster shape wider. Click Apply and OK



10. You can observe on the screenshot below that the style has been updated on the map canvas.



11. One unique feature of Cluster maps is the way they behave as the user zooms in and out of the map. The points cluster more as I zoom out of the map as seen on the screenshot below.



12. The points cluster even the more as I zoom out further (See screenshot below).



Thank you for following the demonstration.
