A method of analyzing seismic survey data in which a transfer function for a geological model is derived by ray tracing techniques applied to theoretical data and the transfer function is applied to actual survey data in order to calculate reflection points () and/or other attributes for each shot ()/receiver () pair. The number of ray tracing calculations which have to be performed in deriving the model transfer function can thus be controlled. A sufficiently accurate transfer function can be derived using theoretical data representing substantially fewer shot ()/receiver () pairs than are used in the traditional ray tracing solution applied directly to actual survey data. Attribute values for actual source ()/receiver () pairs are estimated by interpolating the transfer function data.
