In the last few years Atomic Force Acoustic Microscopy has been developed to investigate the elastic response of materials at the nanoscale $^{[1],[2]}$. We have extended this technique to the real-time mapping of nanomechanical properties of material surfaces. This mapping allows us to investigate the local variation of elastic properties with nanometer resolution and to reduce the uncertainties that arise from single measurements. Quantitative measurements are acquired by first performing an accurate calibration of the elastic properties of the Atomic Force Microscope’s probes with respect to single crystal reference materials. A wide variety of surfaces with different mechanical properties have been investigated to illustrate the applicability of this technique. \\ $^{[1]}$ U. Rabe \emph{et al.}, Surf.
