High resolution Halpha velocity fields provide important observational constraints on the dark matter distribution in low surface brightness and dwarf galaxies. These two-dimensional data show that dark matter-dominated galaxies tend to be more consistent with cored halos than cuspy halos, at odds with theoretical expectations. Using N-body/smoothed particle hydrodynamics simulations of galaxy formation in cuspy spherical and triaxial dark matter halos, as well as cored dark matter halos, we "observe" the simulated galaxies under a variety of realistic observing conditions. We use these mock IFU velocity field observations to determine how well the underlying dark matter halo can be recovered and to test the hypothesis that cusps can be obscured by triaxial dark matter halos.
