Abstract
We consider a problem of formal evaluation of spatial resolution in seismic tomography. We have shown that a traditional method of resolution estimate based on calculation of the resolution matrix appears to be misleading in a case of using the parameterization grid with different spacing. We have proposed an alternative algorithm based on reconstruction of a series of unit anomalies of fixed shapes. Furthermore, we have developed an algorithm for the direction dependent resolution estimates.
