With the aim of providing the complete demography of galaxies in the local Universe, including their nuclear properties, we present SPRING, a complete census of local galaxies limited to the spring quarter of the Northern sky (10h<RA<16h; 0{deg}<Dec<65{deg}). The SPRING catalogue is a flux- and volume-limited sample (r<17.7mag, cz<10000km/s) of 30597 galaxies, including the Virgo, Coma and A1367 clusters. Images and spectra were individually examined to clear the sample from unwanted entries. To inspect possible secular and environmental dependencies of the various nuclear excitation properties (SF vs. AGN), we perform a multidimensional analysis by dividing the total sample according to (i) their position in the (NUV-i) vs. Mstar diagram, (ii) local galaxy density, (iii) stellar-mass, (iv) halo-mass of the group to which galaxies belong, and (v) neutral Hydrogen content. We present a new calibration of the optical diameter-based HI-deficiency parameter HIdef employing a reference sample of isolated galaxies extracted from SPRING. At intermediate distances between Virgo and Coma, we identify a ring-like structure of galaxies constituted by three large filaments, each with approximately 20h^-1^Mpc length, mostly composed of blue-cloud galaxies with stellar-mass Mstar~10^9.5^M_{sun} and becomes 40% for Mstar<~10^10.5^M{sun}, whereas, for Mstar~10^9.510^M{sun}_, increases in galaxies belonging to the green valley.
