Server side clustering

[Giorgi]

Hey guys,

I need to implement server side clustering. Do you have some ideas how to do this? Or links to tutorials?

e.g. what I want say:

1. user is on some zoom level

2. based on this say server sends only two points - but these points are really clusters, so they each have counts

3. Now, on map I show these two points, with counts as marker icons (e.g. one marker says 20012 other says 342
4. Now if user zooms further, server will send another cluster of icons, and so on.

I hope you have an idea what I want. Any hints how to implement this? Or if you know tutorial, or plugin for this?

 you'll need to use an ajax call to load a GeoJSON data set .

 

1. user is on some zoom level

 Zoom level can be sent to the server with map.getZoom()

 

2. based on this say server sends only two points - but these points are really clusters, so they each have counts

This will be the tricky part, perhaps the code from markercluster can be ported

 

3. Now, on map I show these two points, with counts as marker icons (e.g. one marker says 20012 other says 342

Return the number of rows in the result set as an attribute in the JSON.

 

4. Now if user zooms further, server will send another cluster of icons, and so on.

Attach ajax call to the zoomlevelschange or zoomend event
