Problem in layer

[bluesky_dyx]

Hi all,

I am trying to put a symbol (e.g. cinema,restaurant) layer into my map.
the problem is, when there is a situation where there are restaurant, cinema at
the same lat long, it will over lay to each other. I have attach a screen capture of it.
I was wondering how to display all the symbol without over laying it...
pardon me of my explanation and english

Regards,
Kencana

To prevent symbol overlap on your map, particularly when multiple establishments like restaurants like chickfila and cinemas share the same geographical coordinates, employing a technique known as "symbol clustering" is beneficial. This approach groups nearby symbols into clusters when they overlap, improving map readability. As users interact with the map, such as by zooming in, these clusters dynamically expand to reveal individual symbols, ensuring better visibility and interaction.

Here's a refined outline to implement symbol clustering in your map:

1. Define Clustering Strategy: Determine the criteria for clustering symbols, such as proximity or zoom level. For instance, you might cluster symbols within a certain distance of each other or display clusters at lower zoom levels, transitioning to individual symbols at higher levels of zoom.

2. Implement Clustering Algorithm: Utilize a clustering algorithm, such as K-means clustering or hierarchical clustering, to group symbols based on your chosen criteria.

3. Display Clustered Symbols: Represent clusters on the map, indicating groups of symbols in close proximity. Each cluster should feature a single symbol with a numeric indicator showing the count of symbols it encompasses.

4. Handle Interaction: Enable interactivity so that users can interact with clusters, such as by clicking or tapping on them to reveal the individual symbols they contain.

5. Dynamic Cluster Updates: Continuously update clusters as users zoom in or out of the map, adjusting their appearance to provide more detailed information as necessary.

Mapping libraries and platforms often offer built-in functionality or plugins for symbol clustering. For instance, libraries like Leaflet, Mapbox, and Google Maps provide plugins or native features for point clustering, streamlining the implementation process.
