Pin clustering has officially arrived in .NET MAUI Maps, bringing a long-awaited capability to improve how dense map data is visualized. The update introduces automatic grouping of nearby pins into cluster markers, helping developers deliver cleaner and more performant map experiences. It also opens up new ways to handle interactions and customize clustering behavior across platforms.

Here’s what you need to know:

What is pin clustering?
Nearby pins are automatically grouped into a single cluster marker when zoomed out. As you zoom in, clusters break apart to reveal individual pins—giving you a cleaner, more intuitive map experience.
Enable clustering
It takes just one property to switch it on. Instantly, nearby pins are grouped into clusters with a count badge showing how many items are inside.
Separate clustering groups
Not all pins should behave the same. Whether it’s coffee shops, parks, hotels, or attractions - you can group them independently using the ClusteringIdentifier.
Handle cluster taps
Want more control? The ClusterClicked event lets you customize interactions—access cluster pins, location, and override default zoom behavior.
Platform notes
Android uses a built-in grid-based algorithm—no extra dependencies needed. iOS & Mac Catalyst leverage native MapKit clustering for smooth animations.
