  Two main strategies have been implemented in mapping the local universe:
whole-sky 'shallow' surveys and 'deep' surveys over limited parts of the sky.
The two approaches complement each other in studying cosmography and
statistical properties of the Universe. We summarise some results on the power
spectrum of fluctuations and Wiener reconstruction of the density field from
the 2dF Galaxy Redshift Survey (2dFGRS) of 230,000 redshifts. We then discuss
future challenges in quantifying the web of cosmic structure in the on-going
redshift surveys.
