  Studies on Near Earth Asteroids (NEAs) throw light on discoveries,
identification, orbit prediction and civil alert capabilities, including
potential asteroid impact hazards. Due to various new observational programs,
the discovery rate of NEAs has drastically increased over the last few years.
In this paper we present the statistical survey and analysis of fundamental
parameters (derived from Photometric and Spectroscopic observations) of a large
sample of NEAs from various databases like IAU Minor Planet Center, European
Asteroid Research Node (E.A.R.N.), Near Earth Objects - Dynamic Site (NEODyS-
2), M4AST and SMASSMTT portals. We also discuss the characterization of NEAs on
the basis of the correlations between theparametersstudied from different
observationsand theirphysical implicationsin understanding the nature and
physical properties of these objects.
