This article addresses the technical challenges of managing multiple markers at identical coordinates in Google Maps API V3. When multiple geographic points overlap exactly, the API defaults to displaying only the topmost marker, potentially leading to data loss. The paper analyzes two primary solutions: using the third-party library OverlappingMarkerSpiderfier for visual dispersion via a spider-web effect, and customizing MarkerClusterer.js to implement interactive click behaviors that reveal overlapping markers at maximum zoom levels. These approaches offer distinct advantages, such as enhanced visualization for precise locations or aggregated information display for indoor points. Through code examples and logical breakdowns, the article assists developers in selecting appropriate strategies based on specific needs, improving user experience and data readability in map applications.
