Why are pins clustered?
Chances are that when you look at larger geographical regions, there will be a large number of map pins to show, especially if you’re trying to look at pins in a large town or city. If we try to show too many map pins that are gathered around an area it could become difficult or impossible to see or select the pin you need. Another issue is that the information for each map pin needs to be downloaded from our databases, stored in your browser and then displayed. The problem is that there’s a limit to the number of map pins that can be displayed by a browser before it starts to slow down and becomes less responsive. So we examine where the pins are before they are sent to the browser for display and cluster them together. This not only reduces the number of pins sent but it also makes it easier to view them on the map. Note: At the most ‘zoomed-in’ map views we don’t cluster map pins. This is so that you can see each individual event location.
