Two quick questions/requests:

1) Have you guys developed any type of example or efficient technique which you could share with us that automatically generalizes/simplifies the vector polygons and/or clustered points based on the user requested zoom level?

I am essentially looking for an efficient technique which would accomplish these generalization techniques on the server side in connection with postgis geometries and then serve the data back to the users browsers with XY coordinates based upon the users map extent. The technique I am looking should serve the data back to user as binary data stored within clipped tiles which html5/canvas extracts and renders based on css rules. Any further explanation and hopefully some examples would be highly appreciated.

2) Within the example you shared I was not able to tell if it would be possible to add hovering capabilities when your roll over individual vector polygons. I am assuming this is possible utilizing your technique but I would appreciate a quick example of how this can be done correctly.

Thanks,

Chris
