The task of the field of nuclear physics called femtography is to image the interna l structure of strongly interacting particles\, from single protons and ne utrons to atomic nuclei. Protons and neutrons are composed of quarks and g luons\, but the precise spatial arrangement of the two valence up quarks a nd one valence down quark\, along with the sea quarks and gluons that cont ribute half of the momentum\, remains unknown. \; A compelling method for deriving dynamical information about the internal structure of the pro ton is through the use of generalized parton distributions (GPDs). \; Two-dimensional Fourier transforms of GPDs provide insight into matter\, c harge\, and radial distributions of the quarks and gluons inside the nucle on. \; We present an expl icit calculation of such transforms in a spectator model framework using p arametric analytic forms of GPDs\, originally constrained using deeply vir tual Compton scattering and lattice QCD data. \; We compare the valenc e quarks to the gluon distribution through\, i.a.\, average radii\, a noti on of distance inside the nucleon\, and we present a novel result for the radius of the gluon density.
