We have recently undertaken a Speroidal Panchromatic Investigation in Different Environmental Regions (SPIDER). The main goal of this project is that of constraining the formation and evolution scenario of massive early-type galaxies (ETGs), by studying their scaling relations (i.e.,the Fundamental Plane) from the optical to the NIR wavebands, and the dependence of these relations on galaxy environment. The sample consists of 5,000 bright (Mr < 20) ETGs, in the redshift range of 0.05 to 0.1, with optical (griz) photometry and spectroscopy from SDSS and NIR (YJHK) photometry from UKIDSS-LAS. We have measured homogeneous photometric and spectroscopic parameters for all the ETGs, and characterized their environment by means of a new comprehensible (from groups to clusters) and extended cluster catalog (SDSS-DR7 area). I will present the Fundamental Plane (FP) relation of the SPIDER sample in the grizYJHK wavebands, showing how the waveband dependence of this relation strongly constrains the variation of stellar population properties (i.e., age and metallicity) along and around the mass sequence of ETGs. These constraints have important implications for the formation and evolution scenario of massive galaxies.
