The HERMES experiment has collected a wealth of deep-inelastic scattering data using the 27.6 GeV polarized lepton beam at HERA and various pure gas targets, both unpolarized and polarized. This allowed for a series of diverse and unique measurements. Among them are measurements that provide information on the threedimensional structure of the nucleon, both in momentum space and in position space. Results of measurements of exclusive ω production on an unpolarized and transversely polarized nucleon target, sensitive to the distribution in transverse-position and longitudinalmomentum space, are discussed as well as the three-dimensional extraction of azimuthal asymmetries measured in semi-inclusive deep-inelastic scattering, sensitive to twist-2 and twist-3 distributions in three-dimensional momentum space.
