[OpenLayers-Users] How to Create buffer around point?

[Robert Buckley]

Hi,

 I need to implement a "simple" buffer tool. The tool should simply place a Buffer zone around the position clicked in the map when the tool is activated.

...the tool should work like this...

1. Activate tool in toolbar
2. Set Radius in map units   
3. Click in map  
4. buffer polygon based on the set radius is created and rendered in the map



My system is Geoserver 2.1.2 / Postgis 1.5

I have done this with an sld and also in postgis ...but I really need the real-time effect in the map!

any help or examples would be great,

yours,

Robert
