  We revisit the model for parametrization of momentum dependence of nucleon
generalized parton distributions in the light of recent MRST measurements of
parton distribution functions. Our parametrization method with minimum set of
free parameters give a sufficiently good description of data for Dirac and
Pauli electromagnetic form factors of proton and neutron at small and
intermediate values of momentum transfer. We also calculate the GPDs for up and
down quark by decomposing the electromagnetic form factors for nucleon using
the charge and isospin symmetry and also study the evolution of GPDs to a
higher scale. We further investigate the transverse charge densities for both
the unpolarized and transversely polarized nucleon and compare our results with
the Kelly's distribution.
