Geoov [1] is a prototype I developed to provide an overview of my geotagged flickr photos.

I am really frustrated with Flickr's maping service, especially the new one they rolled out a few years ago. I wanted people to see at a quick overview everywhere that I have been and geotagged photos. You can't put all of the photos on the map at the beginning because it will be too crowded and slow.

MarkerClusterer does all the heavy lifting for the clustering (why I picked Google Maps). If you click on a marker or zoom in, it replaces the marker with several smaller markers. I had to suck down all of my geotagged photos to my database (about 11,000 photos) and I print a JSON version fairly quickly from my db.

It initially only works for my photos. Next thing I am going to add is clicking on a marker opens the photo. You might have some issues in older (non JS optimized) browsers.

Flickr employees - please take a hint and change that awful pubic mapping system.

Improvements

I did a few improvements to speed it up. I made clicking on an item load the data by AJAX so the data is not always there. I also combined markers that were in the same exact position into "gangs" to cut the number of points from 11,000 to 4,000. This was a challenge because I had to get MarkerCluster to include the points and their counts.
