[Cartoweb-users] recentering on id

[Emmanuel Belo]

Thank you, Alex, for your input! Now that i have the right metadata, it 
recenters well around the polygon.

(new) Layer of the mapfile:

LAYER
   METADATA
     "id_attribute_string" "id"
   END
END

Ids doesn't need to be unique. If 2 polygons have the same id, it 
recenters around both.

By the way, would it be difficult to implement a "contains" querystring 
to replace the actual "is" query ?

Best regards,

Emmanuel
