[OpenLayers-Users] Leverage Point

[J.Alejandro Martinez Linares]

Hi people i need your help, i got some layers, all of them are points 
types, but i need to make a leverage point i mean and influence point,  
in a same layer, in other word with an example, i need that the user can 
draw a circle in the map with an specific radius, and in that circle the 
system send that portion of area of the map and filter if the selected 
area by the circle enclose some of the points of other all layers, if 
that ocurr, then they are converted in vectors and then shown, i need 
ideas please, thanks to all.
