  We present temperature maps of RS CVn star lambda Andromedae, reconstructed
from interferometric data acquired in 2010 and 2011 by the MIRC instrument at
the Center for High Angular Resolution Astronomy Array. To constrain the
stellar parameters required for this imaging task, we first modeled the star
using our GPU-accelerated code SIMTOI. The stellar surface was then imaged
using our open source interferometric imaging code ROTIR, in the process
further refining the estimation of stellar parameters. We report that the
measured angular diameter is 2.742 +/- 0.010 mas with a limb-darkening
coefficient of 0.231 +/- 0.024. While our images are consistent with those of
prior works, we provide updated physical parameters for lambda Andromedae
(R_star = 7.78 +/- 0.05 R_odot, M_star = 1.24 +/- 0.72 M_odot, log L/L_odot =
1.46 +/- 0.04).
