The central point of the modern seismic technology is the velocity model construction and obtaining the trustful depth image. There are different approaches and ways of compensation of subsurface heterogeneities. However, the problem includes not only compensation of the influence of the complex subsurface structure but also for the influence of the elevation surface. In case of complex elevation that varies greatly it is important to have a reliable technique of compensation for its influence on kinematical parameters of seismic data. The new technique of the subsurface heterogeneities compensation in seismic data is offered in this paper. The method is based on the refracted wave modelling and tomography. It allows involving into the correction the surface geometry variations.
