the MarkerClusterer cannot help if the markers have the same position. But it is possible to improve the zoom behaviour of the v3 MarkerClusterer. It zooms to the potential space occupied by the markers, not the actual space, so we can modify it to calculate the bounds of the markers in the cluster and zoom to this.
for markers with the same position, you would have to identify unique business locations, and then change the infowindow to show all businesses at the one location. see the following map for a way of doing this: http://www.william-map.com/20100425/1/locations.htm for example, click on cluster near Dresden (37 markers), Leipzig (10 markers), Leipzig City (3 markers), and then you will have a single marker at Leipzig Centrum Ost, which has 2 businesses at this one address. The info window has little tabs to select each business. on the original map, the cluster near Dresden had 51 markers, then 21 markers for the Leipzig area, then 13 markers, then 7 markers ... with a much slower zoom to the discrete markers. ... -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
