Abstract：Spatial resolution of seismic data is dependent on observing positions and directions, while the conventional definition of resolution is limited to horizontal and vertical resolution only. Therefore the concept of the directional spatial resolution is put forward in the paper, and a general formula of 3D directional spatial resolution is deduced. Also, it is proved that the formula deduced in this paper is in consistent with the spatial resolution formula of 2D common offset data in constant velocity medium derived by Vermeer and the resolution expression derived on the Rayleigh resolution criteria by Ma Zaitian. This may indicate the correctness and generality of the directional spatial resolution formula proposed in the paper.
