<p>Note that the geometries drawn are planar geometries and the
metrics returned by the measure control are planar measures by
default. If your map is in a geographic projection or you have the
appropriate projection definitions to transform your geometries into
geographic coordinates, you can set the "geodesic" property of the control
to true to calculate geodesic measures instead of planar measures.</p>
to true to calculate geodesic measures instead of planar measures.
Also you have the possibility to set the "immediate" property to true
to get a new calculated value once the mouse has been mooved.</p>
