Hello dear sir,
    I am very appreciated with the OpenLayers 2.5.I am very like the new 
features added.
I have a problem to consult you about the methods
           map.getScale() ,
           feature.geometry.getLength()
           and feature.geometry.getArea().
    Because the coordinates I used in the map is longitude/ latitude, and I 
donnot know
 which units you carried,I wonder are they  calculated correctly.I want to know 
how the methods  programed,and what js file they are in?Thank you very much!    
                                                       Sincerely yours,         
                                                        Yang
