  We study the topological content of the SU(3) vacuum using the
renormalization group (RG) mapping method. RG mapping is a simple smoothing
algorithm, in which a series of APE-smearing steps are done while the
topological content of the configuration is carefully monitored. This
monitoring process makes it possible to separate true topological objects from
vacuum fluctuations and allows an extrapolation to zero smearing steps. Using
RG mapping we have measured the instanton distribution and topological
susceptibility for SU(3) gauge theory. We arrive at a value for the topological
susceptibily, ${\chi}^{1/4}$ of 203(5) MeV. The size distribution peaks at
$\rho=0.3$fm, and is in good agreement with the prediction of instanton liquid
models.
