Two-dimensional maps of the stellar and gas kinematics of the bar and starbursting circumnuclear region in the barred spiral galaxy M100 are presented. In this progress report, we present maps of the total intensity, mean velocity and velocity dispersion for the stars and the gas. The gas velocity field shows significant kinematic signatures of gas streaming along the inner part of the bar, and across the miniature spiral arms in the nuclear pseudo-ring. The stellar velocity field, presented here for the first time, also shows non-circular motions. The gas velocity dispersion is notably smaller where the star formation occurs in the nuclear zone and HII regions. We outline our further plans with the data set.
