Will ClusterMarker & MarkerClusterer work with v3? If not whats the missing piece to cause issue? Thanks

Here is a marker manager for GMap v3, in case anyone is looking for it.

Wow, this is a great resource. Thank you very much for taking the time to compare all of these different techniques and for creating the demo page to sample them all!

Hi If someone is interested in an example of the MarkerClusterer in action, I'm using it to display my photos.

For those of you who are looking for a clustering solution for the v3 API: There’s a new one i wrote at work, called Fluster and available for download at http://blog.fusonic.net. There will be an improved version the next days which speeds up the whole process of clustering significantly.

You might also be interested in my clusterer for Flash based on a serverside PHP solution I found. More info and a demo here:

I’m working on your example clustermaker. Line 6 cluster.refresh() dosen’t work. refresh is not in the cluter2.js. Please advice. Thank you

Прикольно! Все очень понятно и грамотно, и в то же время без умствований и самолюбования, и на доступном языке. Редкий случай когда человек делится актуальной и полезной инфой. Спасибо автору!

ricco: I agree with you that they are both good clusterers, definitely two that should be considered when choosing the right clusterer for the job. Also thanks for the tip about using markerLight with the clusterers. Could come in handy!

Hello,

i tried some speed tests with markerClusterer and ClusterMarker and I noticed that with a lot of markers ( > 1000) markerCluster seems to takes the advantage ( but sometimes not -_-’ ).

But once the markers are clusterized, i think i prefer the markerClusterer: when you drag the map, the markers don’t desappear quickly while clusters are redraw.

Furthermore, if you click on a cluster, the comportement is different : markerCluster will try to show a marker at the maximum zoom that is possible ( which sometimes is cool and sometimes not), while markerClusterer will bring you step by step ( zoom level by zoom level) to the marker. as for me, i prefer this way.

conclusion : i think they are two good clusters. People have to try them both. ( although MarkerClusterer has little issues at this date : http://code.google.com/p/gmaps-utility-library-dev/issues/list )

ps: both can works pretty well with MarkerLight. If you want to combine MarkerLight and MarkerClusterer, you have to add 3 methods to the markerLight class : hide(), show() and isHidden() ( see Mike Williams’s elabels to find these methods).

If you want to use clusterMarker with markerLight, you have to do a very little hack in cluster marker concerning the set of GIcon ( that you don’t need no more). You can even hack the clusterMarker to create a GOverlay ( as markerCkusterer rather than a GMarker).

Clayton Narcis: There's no official version of MarkerManager for V3 but I know that some people have ported it but I don't know if they are publicly available.

Great write up. Was wondering is any of this marker manager being ported over to Google Map V3?

Please delete my last post.

This is a sample of server side cluster based on admin border. Just for some one interest in that topic.

Thank you SOOO much for the resources! I tried programming a class that would query my database for only the markers that where within the google maps box, and it was a MESS and had a million glitches! If I had known earlier that these sources were available, I would had never bothered querying my database like I did. Again, thanks a million.

To time actual marker display, couldn’t the image src instead of being a http url to a php script, just be a javascript: url so that you can effect a method call on the display of the marker?

Jason: Good catch! Thanks for noticing! I've corrected the example now.
