  All-sky thermal and kinetic Sunyaev-Zel'dovich (SZ) maps are presented for
assessing how well the PLANCK-mission can find and characterise clusters of
galaxies, especially in the presence of primary anisotropies of the cosmic
microwave background (CMB) and various galactic and ecliptic foregrounds. The
maps have been constructed from numerical simulations of structure formation in
a standard LCDM cosmology and contain all clusters out to redshifts of z = 1.46
with masses exceeding 5e13 M_solar/h. By construction, the maps properly
account for the evolution of cosmic structure, the halo-halo correlation
function, the evolving mass function, halo substructure and adiabatic gas
physics. The velocities in the kinetic map correspond to the actual density
environment at the cluster positions. We characterise the SZ-cluster sample by
measuring the distribution of angular sizes, the integrated thermal and kinetic
Comptonisations, the source counts in the three relevant PLANCK-channels, and
give the angular power-spectra of the SZ-sky. While our results are broadly
consistent with simple estimates based on scaling relations and spherically
symmetric cluster models, some significant differences are seen which may
affect the number of cluster detectable by PLANCK.
