Use geodesic measures
For distance measurements, the distances are computed as distances between
projected longitude,latitude coordinates of the points.
Note that the area measurements, 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 `Use geodesic` property of the control
to true to calculate geodesic measures instead of planar measures.
