We detail an innovative new technique for measuring the 2-D velocity moments(rotation velocity, velocity dispersion and Gauss-Hermite coefficients h$_3$and h$_4$) of the stellar populations of galaxy halos using spectra from KeckDEIMOS multi-object spectroscopic observations. The data are used toreconstruct 2-D rotation velocity maps.  Here we present data for five nearby early-type galaxies to ~3 effectiveradii. We provide significant insights into the global kinematic structure ofthese galaxies, and challenge the accepted morphological classification inseveral cases. We show that between 1-3 effective radii the velocity dispersiondeclines very slowly, if at all, in all five galaxies. For the two galaxieswith velocity dispersion profiles available from planetary nebulae data we findvery good agreement with our stellar profiles. We find a variety of rotationprofiles beyond 1 effective radius, i.e rotation speed remaining constant,decreasing \emph{and} increasing with radius. These results are of particularimportance to studies which attempt to classify galaxies by their kinematicstructure within one effective radius, such as the recent definition of fast-and slow- rotator classes by the SAURON project. Our data suggests that therotator class may change when larger galacto-centric radii are probed. This hasimportant implications for dynamical modeling of early-type galaxies. The datafrom this study are available on-line.
