A04 SHEAR WAVE DEPTH VELOCITY MODEL BUILDING BY PS STEREOTOMOGRAPHY Abstract 1 PS Stereotomography was proposed for VS velocity model building from multi-component seismic datasets. No pairing of PP and PS events is a priori required leading to a very practical solution for building the VS velocity model building. After several applications on real and synthetic datasets a semi-automatic strategy has now emerged for PP-PS Stereotomography. We present here a state of the art and a perspective view for PS Stereotomography from OBC data based on synthetic and real data applications. Introduction Stereotomography is a method for estimating velocity macro
