Nearby, active stars with relatively rapid rotation and large starspotstructures offer the opportunity to compare interferometric, spectroscopic, andphotometric imaging techniques. In this paper, we image a spotted star withthree different methods for the first time. The giant primary star of the RSCanum Venaticorum binary $\sigma$ Geminorum ($\sigma$ Gem) was imaged for twoepochs of interferometric, high-resolution spectroscopic, and photometricobservations. The light curves from the reconstructions show good agreementwith the observed light curves, supported by the longitudinally-consistent spotfeatures on the different maps. However, there is strong disagreement in thespot latitudes across the methods.
