The geometric localization technique [Pizzo and Biesecker, 2004] utilizes a series of lines-of-sight from two space-based coronagraphs to determine gross propagation characteristics of coronal mass ejections (CMEs) in three-dimensional space. The polarimetric localization technique [Moran and Davila, 2004] uses the percent polarization observed by a single coronagraph to obtain a three-dimensional reconstruction of a CME. We apply both techniques to STEREO/SECCHI/COR2 data to determine the speed and direction of propagation, as well as the size, shape, and orientation of some recent CMEs, including the event of 3 April 2010. The results obtained from this analysis can be used as inputs to the numerical MHD code, Enlil, which will track the evolution of the CME and its interaction with the solar wind.
