Chiral Even and Odd Generalized Parton Distributions for valence quarks were obtained in a "flexible" spectator model based on the covariant scattering matrix approach. The parametrization of the GPDs was constrained by nucleon form factors, PDFs and some deeply virtual Compton scattering data. The model is extended to sea quarks and gluons. A broad range of measured and measurable electron, muon and neutrino processes, including cross sections and polarization asymmetries, are compared with existing data. Predictions are made for processes sensitive to the newly parameterized GPDs.
