  In order to investigate the properties of large-scale structures of galaxies
in the universe, we present an analysis of their spatial distribution at
z$<$0.033. We used the LEDA extragalactic database containing over 1 million of
galaxies covering the all-sky and the SDSS data included in the public release
DR1, yielding to a sample of around 134,000 galaxies having a measured redshift
in two survey areas representing 690 sq. degrees. The results of the study are
2D, 3D maps and magnitude number counts of galaxies, drawn from B-band samples.
