If you\u2019ve ever loaded a map with dozens \u2014 or hundreds \u2014 of pins, you know the result: an overlapping mess that\u2019s impossible to interact with. Starting in .NET MAUI 11 Preview 2<\/a>, the Map control supports pin clustering out of the box on Android and iOS\/Mac Catalyst.<\/p>\n

What is pin clustering?<\/h2>\n

Pin clustering automatically groups nearby pins into a single cluster marker when zoomed out. As you zoom in, clusters expand to reveal individual pins. This is a long-requested feature (#11811<\/a>) and one that every map-heavy app needs.<\/p>\n

Enable clustering<\/h2>\n

A single property is all it takes:<\/p>\n

<maps:Map IsClusteringEnabled=\"True\" \/><\/code><\/pre>\n
That\u2019s it. Nearby pins are now grouped into clusters with a count badge showing how many pins are in each group.<\/p>\n
Separate clustering groups<\/h2>\n
Not all pins are the same. You might want coffee shops to cluster independently from parks, or hotels separately from attractions. The ClusteringIdentifier<\/code> property on Pin<\/code> makes this possible:<\/p>\n
map.Pins.Add(new Pin\n{\n    Label = \"Pike Place Coffee\",\n    Location = new Location(47.6097, -122.3331),\n    ClusteringIdentifier = \"coffee\"\n});\n\nmap.Pins.Add(new Pin\n{\n    Label = \"Occidental Square\",\n    Location = new Location(47.6064, -122.3325),\n    ClusteringIdentifier = \"parks\"\n});<\/code><\/pre>\n
Pins with the same identifier cluster together. Pins with different identifiers form independent clusters even when geographically close.<\/p>\n
Handle cluster taps<\/h2>\n
When a user taps a cluster, the ClusterClicked<\/code> event fires with a ClusterClickedEventArgs<\/code> that gives you access to the pins in the cluster:<\/p>\n
map.ClusterClicked += async (sender, e) =>\n{\n    string names = string.Join(\"n\", e.Pins.Select(p => p.Label));\n    await DisplayAlert(\n        $\"Cluster ({e.Pins.Count} pins)\",\n        names,\n        \"OK\");\n\n    \/\/ Suppress default zoom-to-cluster behavior:\n    \/\/ e.Handled = true;\n};<\/code><\/pre>\n
The event args include:<\/p>\n
