![]() Viewport marker management - restricting the markers rendered on the map into only those that exist within the viewable area.Cluster centroids are generally specified algorithmically through iteration of the existing marker locations. Distance-based clustering - it is similar to grid-based clustering, except instead of creating clusters of fixed square bounds, clusters are created based on the distance between the marker and a cluster centroid.Grid-Based Clustering - it works by dividing the map into squares of a certain size (the size changes at each zoom) and then grouping the markers into each grid square.There are several approaches how to solve this problem: Straight-forward javascript approach with placing Google Maps API markers didn’t work well as the page worked extremely slow and that was unacceptable. ![]() Objects coordinates are taken from our server-side service and we should have dynamic filtering of this data on client side. This article briefly describes our experience in development interesting component for multiple markers/objects on google maps in web application.įor one of our projects we required to show more than 20,000 elements at the same time on google maps in web browsers. ![]() We continue set of articles about interesting technology areas and solutions we have implemented or encountered in our projects. ![]()
